Poison Swamp

Poison Swamp Ultimate Weapon

Poison Swamp is an Ultimate Weapon that has a percent chance on enemy death to spawn a poison swamp that deals a percent of tower damage per second, stays active for a period of time. (Accounts for crit/super crit factor and chance)

Use

Poison Swamp is a pretty weak Ultimate Weapon at first. It gets better with later upgrades that allows you to stun enemies and apply rend to them, making them weaker and easier to kill.

If an enemy touches a Poison Swamp, they are poisoned forever. They receive the damage-per-second until they die. So touching a second poison swamp doesn't increase how much damage they take.

HOWEVER, if an enemy enters an overlap between two Poison Swamps, both swamps have a chance to stun (if you have Poison Swamp Stun). This means they are twice(ish) as likely to get stunned.
Although, There's a limit to how many enemies can be on the screen at once (should be 100). Once that limit is reached, no more enemies can appear. So if you're farming, stun will delay enemies dying from orbs and lower your kill-per-minute, hence lower your coins-per-minute.

In addition, if you have Swamp Rend, then the damage that the enemy takes from Poison Swamp will increase as the enemy is rended by projectiles. Them touching another Poison Swamp will not effect this.

Really good with a Harmony Conductor Module, which adds chance for Poisoned enemies to miss (half the chance for bosses)
