It appears using Slime Spit will not work with an ally between you and your foe : the talent goes on countdown but no animation occurs, and neither my ally nor my ennemy are damaged.
Isn't Slime Spit with Through the crowd supposed to count 1 hit (but no damage) on the ally, then bounce to score a second hit on the foe ?
Second to that (already mentionned in the forum) Through the crowd seems capped at 5 allies for the saves (a +50 is still nice too

Even with these two limitations the prodigy seems very promising with an Oozy !
