Guides & Information

Author Rating: C Roles: Melee, Fodder, DPS Synergies: Every unit

• Living Meat-shield that can be spawned by other Grell units

• Dies automatically after (roughly) 40 seconds

• Pathetic individual stats, strength in horde numbers and chip damage

• Don't underestimate the value an extra ten 4 damage attacks can do

• Can use Frenzy too for some reason

• Can be charged into enemies to distract & bait AoE attacks

• Ineffective against armored targets (4 Damage per attack)

• Can body-block other Arkanids; Walks through regular units

• Shown here for convenience; All combat units can utilize Frenzy

Author Rating: B-

Roles: Melee, Fodder, DPS, Hexite Dump

Synergies: Every Unit

• Swarmy melee unit, spawns in groups of three

• Cheap and with decent stats

• Surprisingly cost-effective

• Very vulnerable to crowd control and AoE effects

• Ineffective against armored targets (6 Damage per attack)

• Is small enough to NOT body-block other Grell melee units

Author Rating: A Best Use: Any Stinger Build

• Exactly what a swarmy unit needs to reach the front-line

Author Rating: C+ Best Use: Stinger Defense

• Attack Speed Buff only applies on Biomass

• Buff brings Stingers to 12 DPS

• Cloak is auto-removed when attacking

• Useful for defense and if you're good with your Biomass spread

Author Rating: D Best Use: N/A

• Sounds cool, is not

• The rest of your army will lag behind and the Stingers will die alone

• 5 Seconds is barely enough time to reach the enemy in many cases

• Can cause issues on large maps where Stingers will path into uncleared enemy bases

• Can synergize okay with Behemoth-focused builds

Author Rating: A Best Use: Any Stinger Build

• Basically one extra Stinger attacking the target ; Slow is irrelevant as enemies do not flee

• Effect does not stack

• Damage affected by enemy armor

Author Rating: C

Roles: Melee, Fodder, Tank, Hexite Dump

Synergies: Stinger, Lasher, Weaver, Harbinger, Behemoth

• Relatively durable melee unit; Competes with Vynthra's two most Reliable Units

• Affordable and with okay single-target damage

• Deprecated by the fact it shares a tech-level with the Mandragora

• Spawns one Arkanid for every 20 damage taken

• Enemy units do NOT reliably switch targets to kill the Arkanids

• Arkanid-spawning is worthless when attacked by targets with AoE

• With double Infusion, T2 Incubator units also spawn Arkanids on every kill, further reducing the Keeper's utility

• Mandragoras can still attack from behind a 1× Infused Keeper; Not Reliable however

• Reavers can barely attack from beyond a 0× Infused Keeper

• This is not a recommended strategy however, as the extra range reduces body-blocking issues and permits them to chomp further into the enemy forces; Stingers work better for this task.

Author Rating: B+

Best Use: Any Keeper Build

• Good upgrade, not game-changing

• Increases the HP given by Infusion

Author Rating: D

Best Use: N/A

• Regeneration applies only out of combat

• Cumulative with the boost from Infusion & other sources

• Does not address the unit's big issues

• Life-steal per attack from later levels deprecates the utility of this upgrade

Author Rating: B

Best Use: Any Keeper Build

• Only affects Arkanids spawned by the Keeper

• Okay upgrade, not game-changing

Author Rating: B+

Roles: Ranged, +Anti-Medium, DPS

Synergies: Stinger, Keeper, Mandragora, Harbinger, Weaver, Reaver

• Basic Ranged Unit ; Solid Performance

• Good Range; Cost-Effective

• Relatively Fragile

• Bulky size for a basic DPS unit; Causes body-blocking

• Can target Air

(No notes.)

Author Rating: A

Best Use: Any Lasher Build

• Very useful, exactly what the Lasher needs

Author Rating: D

Best Use: N/A

• Making your ranged unit faster than your melee tanks is a recipe for disaster

• It does not address the unit's actual weaknesses

• This is a perfect example of a PvP upgrade copied into Coop

Author Rating: B+

Best Use: Any Lasher Build

• Reliable, bound to be useful sometime during any mission

Author Rating: D

Best Use: N/A

• Cloak is removed when the unit attacks

• Not useful in coop ; Useless without a hold-fire button

Author Rating: A

Roles: Melee, Crowd Control, DPS, +Tank

Synergies: Every Unit, except Keepers

• Powerful Melee Brawler

• Excellent against ground units

• In terms of Infusion, still seems to count as a T2 unit

• Affordable and durable ; good Armor

• Deals splash damage ; Good DPS output

• Has a range of 3 but is still considered melee

• Has some issues with body-blocking at 2x Infusion

• Utility varies on the enemy composition

• Will use closest-possible if the target is out of range

• Using Tunnel at the back of an attack wave can leave Mandragoras out of range of healers

Author Rating: A

Best Use: Any Mandragora Build

• Reliable and powerful

• Remember AoE damage counts for Life-Steal

Author Rating: B-

Best Use: Mandragora-Reaver, Mandragora-Keeper Builds

• A less reliable choice

• Mostly useful if you use Mandragoras alongside dedicated Tanks like Reavers

• Less useful when facing Xol

Author Rating: S

Best Use: Any Mandragora Build

• God-tier synergy with the Frenzy ability, which now gives Mandragoras 90% Attack Speed

• Great synergy with the Life-Steal Level upgrade

Author Rating: C+

Roles: Ranged, Anti-Heavy, Burst, Caster

Synergies: Stinger, Lasher, Keeper, Mandragora, Weaver, Reaver

• Shockingly Affordable yet inefficient second-line support

• The Trick is to have a Front-line, and then 4-5 of Harbingers behind it

• Size and cost of roughly 2 Stingers ; DPS of only one

• Suffers from severe body-blocking when 2x Infused

• Body-blocking hurts casting ability and also hurts all other units in your army composition

• Thus, the one unit in Vynthra's roster that should only be infused once

• Heavily reliant on gimmicky ability damage

• +100% Damage against Heavy

• Cannot attack air

• Its casting range is insufficient when severe body-blocking is taken into account

• The very small AoE demands a stationary target

• Each Infusion increases the AoE by 50%, but that is not justification to infuse Harbingers twice

• Focus on enemy tanks, static defenses, and Heroes

Author Rating: D

Best Use: N/A

• Hardly an useful upgrade unless you want them to tank

• Vynthra has far more efficient dedicated tank units

Author Rating: B+

Best Use: Any Harbinger Build

• This is a 42.1% increase.

• Makes them faster than all Grell Units except Stingers & Weavers

• Useful for getting into position for using Eruption

• It is an indirect solution to the problem

Author Rating: B+

Best Use: Any Harbinger Build

• Must-have upgrade when utilizing Harbingers

• Still too small to be of much use

Author Rating: D

Best Use: N/A

• Utility pales in comparison to its counterpart

• 25 less HP to use is meaningless

Author Rating: C

Roles: Artillery, Crowd Control, Burst

Synergies: Stinger, Mandragora, Harbinger, Weaver, Reaver

• Siege Unit, great for mobile defense

• Neat but not needed

• Competes with the best static defense in Coop

• Did I mention you can Air-Drop static defense and a wall that heals it?

• Expensive, as far as Vynthra units go

• Relatively slow

• Great Range (27), meh damage, deals splash

• Projectiles do not track, will miss moving targets

• Assume actual firing rate is 2sec slower, accounting for projectile travel delay

• Has a minimum range of 3.75

• Spreads Biomass around across its minimum range area

• Benefits very little from Infusion; Best to focus on numbers instead

• Requires a Synapse Canopy

• Deals +75% against Buildings

(No notes.)

Author Rating: C

Best Use: Thresher Siege Builds

• Subpar damage ; Unreliable

• Basically one little Stinger's worth of damage

Author Rating: A

Best Use: Any Thresher Build

• Exactly the kind of upgrade a Thresher needs for Coop

• Not useful for static/prolonged defense

Author Rating: A+

Roles: Melee, Tank, Burst, +Crowd Control, Caster

Synergies: Every Unit, except Keepers

• Very powerful and reliable melee tank

• 2k+ HP at 2x Infusion

• Great DPS output

• Quite large, which means it will reliable be targeted by the enemy

• Ravage/Charge ability ensures it can be at the front-line every fight

• Spawns 4 Arkanids upon death

• Has a range of 1.75 but is still considered melee

• Cannot target Air

• Will use closest-possible if the target is out of range

• Knockback and Damage effects apply to all enemies on the path

• Units do not need to be fully within the reticle to be hit

Author Rating: S

Best Use: Any Reaver Build

• Amazing upgrade, ensures the Reaver can get to the Front-line no matter where it is in your formation

• Can be used to smash through waves and eliminate weaker units

Author Rating: B

Best Use: Reaver Mandragora Build

• Utility generally pales in comparison to its counterpart

• Useful alongside Tunnel Mandragoras

• Can be helpful when facing tougher opponents

Author Rating: A-

Roles: Ranged, Anti-Air, Burst, Healer, Caster

Synergies: Every Unit

• Good healing ability; Multiple Weavers can heal the same target

• Good range, not-quite-fragile

• Decent DPS, but out-classed by Lashers against Ground

• Excellent support against large numbers of enemies due to their ability

• Damage competes with healing weapon ; Cannot have both simultaneously

• Weavers can quickly switch weapons mid-combat; Healing, shooting once, healing again

• Infusion increases heal range

• Fast, has a tendency to run ahead of army; Micro to ensure they remain at the back

• As such, requires a mobile front-line unit like Reavers with Ravage, Stingers, etc

• Caution: Weavers are often pushed into the enemy by allied melee units

• Can also lag behind to heal allied units, if A-clicked towards a position

• +100% Damage to Air

• The projectile must travel to its target, creating a one-to-four-second delay before impact

• Cast it ahead of enemies rather than in the middle to reduce that delay

• Remember giving other commands to the unit (like A-moving) cancels the ability casting

• Thus, the proper way to use this ability is to Attack, Frenzy and then Cast the ability

• It moves

• The poison refreshes until the pool expires or enemies leave it

• Arkanid spawning stacks with other sources

• Can hit air

Author Rating: B-

Best Use: Any Swarmy Weaver Build

• Generally less useful than its counterpart

• Weavers are efficient-enough healers, don't rely on other units just to get this upgrade

Author Rating: A

Best Use: Any Weaver Build

• Reliable and worthwhile upgrade, covers 2/3 of the unit's Roles

Author Rating: A

Roles: Ranged, +Artillery, Anti-Heavy, Burst, Crowd Control, Caster, Flying, +Transport

Synergies: Every Unit

• Designated Anti-Heavy unit

• Slower projectile attack, low DPS for its cost and size

• Expensive, by Vynthra standards

• Greatly empowered by Infusion

• Size increase from Infusion makes it harder to control ground units under a Behemoth

• In spite of being a flying unit, its attacks are still blocked by enemy buildings

• Less recommended when facing enemy Grell, its Flame attacks can be confused for those of enemy Behemoths

• +200% Damage to Heavy

• Cannot target Air

• Slow projectile, unreliable; Misses very often

• Genuinely not worth the effort to make it work

Author Rating: C-

Best Use: N/A

• Only useful if you plan to transport units in a Behemoth

Author Rating: A

Best Use: Any Behemoth Build

• Always useful; Helps alleviate issues of sight-blocking due to Behemoth size

• Permits besieging objectives from a safe distance

Author Rating: B-

Best Use: N/A

• Very niche

• Carrying capacity is not increased with Infusion

• However Infused units cost more to be carried by the Behemoth

• Fast loading and unloading

• Loaded units cannot attack, but they are healed while inside

• Loaded Arkanids & other temporary units can still expire

• Keep in mind the Behemoth, without the Speed upgrade, is still slower than most of your Roster

• Frenzy upgrade largely deprecates the need to use Behemoth Transportation
