How to use the Poison Tower
Poison is built around critical strikes. It costs more than Arrow, Fire or Ice, so build it once your economy is running rather than as an opener.
Virulent Strain makes poisoned enemies take more damage, and Corrosive Burns turns crits into true damage. The Solvent Ultimate strips resistances, so every tower near it benefits too.

Solvent
Every hit applies poison stacks. Each stack dissolves a fifth of every resistance the enemy has; at five stacks it resists nothing from any of your towers.
Ultimates come from cursing a Rank 5 tower on the Rift Wheel (1,000 gold). How cursing works.
