Chemist

Alchemist · 10 Kugan skills · 5 active, 5 passive

Chemical is alchemy with the safety labels scraped off.

Its specialists do not ask whether a reaction is stable. They ask whether it reaches the enemy before exploding, burning, poisoning, dissolving or turning the air itself into a problem. Every bottle is a theory; every battlefield is a laboratory with poor ventilation.

The Chemical path pushes offensive alchemy. Pharmacy improves explosive and acid damage, Demonstration, Acid Terror and Acid Demonstration become the core attacks, and item recovery helps sustain the cost of bottles. Toxic, Acid and Fire Clouds create temporary hostile zones, Chemical Effect arms allies with reactive reagents, and Chemical Bomb sends suicidal constructs forward to detonate on contact.

Chemical is messy, practical and brutally direct. It controls space by making that space unsafe to occupy.

To fight Chemical is to stand inside someone else's experiment.

The conclusion is usually loud.

Tank★★☆☆☆VIT helps slightly, but the specialization is offensive and positional rather than defensive.
Tactical★★★★☆Cloud placement, reagent choice, bottle economy and bomb timing make Chemical highly position-sensitive.
Healer☆☆☆☆☆Chemical offers no healing role.
Buffer★★★☆☆Chemical Effect can give allies reactive status effects, but support is secondary to damage and control.
Debuffer★★★★★Poison, acid, fire, burning, stone, freeze, blind and weapon-break effects give Chemical excellent disruption.
DPS Melee Physical★☆☆☆☆The path is not designed around personal melee attacks.
DPS Ranged Physical★★★☆☆Acid Terror, Demonstration and bombs provide strong thrown or deployed physical-style pressure.
DPS Magical★★★☆☆Cloud and summon power scales with INT, giving Chemical a notable magical-stat damage component.
Special★★★★★Deployed clouds, reactive reagents and suicide bombs create a very specific hazard-control identity.
Resources★★★☆☆Chemical Demo can refund bottles, but the path still cares heavily about alchemical item costs and cooldowns.
Mobility★★☆☆☆Chemical controls zones rather than moving quickly through them.

The user can choose from 5 types of reagents.

He and his party members (within 5x5) then benefit from an effect that applies a status or effects that depends on the chosen reagent when attacked.

Reagents are:

Saltpetre: Can cause Burning (10 seconds) to the attacker.

Basilicus: Stone Curse (5 seconds) to the attacker.

Cryonics: Freeze (5 seconds) to the attacker.

Glistering: Blind (10 seconds) to the attacker.

Brinks: Can autocast Weapon Breaker level 10 on the attacker (20% chance to break its weapon when occurring).
