Level 42 Mastermind here, and To go along with Doc Abominbables quote above.
Bile Spray: I have it with 3 green SO Damages, and 1 Recharge. Yet still, it does less effect than my M30 grenade with 2 SO damages and no recharge. As much as I like the animation (and it is funny) It really has no use for a mastermind. Even in mayhem missions, I can use the grenade to clear out rubble/cars, but the bile spray takes just too long to recharge to be useful.
Also, No hard numbers, but let me use anecdotal evidence. A level 42 Character vs a level 13 (Yes, 13) Luddite Lt. should not need two hits. Nor should He need 3 hits on a level 12 Arachnos Boss, with a power thats supposed to be one of the great secrets that must be learned at the highest levels of power.
Animation: Hilarious. Power: Really disappointing.
