Lore: Zerg development of creatures with new forms of resilience have resulted in the Toximancer. First appearing on Sanctum, Vespus finds immediate purpose in his existence as he plunged directly into combat in the midst of an epidemic.
Toxi's ability to passively kite enemies and chase makes him an excellent ganker and carry. His Toxic Tornado allows him to be a very strong presence in teamfights.
Toxi is a ranged, autoattack carry or int caster who has a suite of slows and AoE Dots (damage over time) effects. His E makes for excellent lane harass, last hitting, and denying, while his ult has incredible damage potential, but by the nature of being a debuff, is countered by parralax or other debuff immunity skills. Max Q or E first for the early game damage. Note that his W can heal structures/towers. Run 4/1/1 talents, taking attack damage, attackspeed, lifesteal, haste, health, and max energy/regen, as his ult has a steep mana cost early on.
