Contagion is a legendary major card out of the Synergy pool. A Venomed enemy's death spreads its Venom to nearby enemies.

Death becomes your delivery system — one Venomed kill infects the neighbors and packs unravel on their own. The heavier your stacks, the nastier the spread. Core poison clear; less relevant against lone bosses.

You can take it once · any ability can be offered it.

It pushes your build toward Poison.
