guess ur right about the reduction to mana but u can still get plenty of mana regen items and +crit on acid rain items. plus its not 150% its 115% + 150% over 3 sec, does it stack if u cast it twice? plus it has a huge radius and range.. wont be bothered by running ranged elites
im just a huge fan of acid rain because it makes me immortal with high all resistance and LOH, mixed with rain of toads and a skorn procing 10k damage because of the high coefficient.
plus u could go slow burn for 115% + 300% over 6 seconds... does anyone know if it stacks... like if i cast it three times in a row will the damage over time overlap or just refresh
