Assassin

Passive - a 5% chance to fully evade any incoming basic attack, taking no damage. Cheap, always-on survivability.

Triggered passive - when struck, drops a smokescreen that absorbs all incoming attacks for 3 seconds and re-hides the Rogue. In-flight projectiles puff harmlessly into the smoke; melee attackers lose their lock and walk away. 15-second cooldown. No mana cost - panic survival reflex.

Each attack applies Deadly Poison for 6s: a flat damage-over-time tick (a fixed amount, not a percent of max HP like regular Poison). Hits from different attackers stack. Costs 0 mana, and counts as a poison debuff (blocked by poison immunity, dispelable).

Invisible to the enemy while out of combat. Sneaks past frontlines, ambushes priority targets, then breaks off and re-stealths. Avoids infantry; targets ranged and casters first.
