The Plague Doctor joins your legion as soon as you own this DLC. He arrives at level 1. He wears the best gear in your bag that he can use. No stage to reach.
Role: damage support from mid range. His damage is poison that stacks and ticks. He weakens enemies for the rest of the team.
Kit: darts that poison. A plague vial that leaves a toxic pool. A miasma that slows. A plague that jumps when an infected enemy dies. His talents add wounds that heal less and an epidemic. Another talent heals the whole team with a transfusion.
Talent tree: his own, like every other hero. Spend the points and shape him your way.
Modes: campaign, the Abyss, World Boss and PvP. Fits any formation you already run.
He opens one more formation slot if fewer than four are open. Then he joins without benching anyone.
Achievements are not affected: every achievement in Idle Legions can be earned without this DLC.
