Yes, got my Succubus from 2nd roll, only legendary slime since however.
last week got ninja and pali in seperate 150 rolls and cpl days ltr TG and succubus on 450roll. before that nothing but elites for 1st 30 days, assin/SQ bunch of dupes. Been going for 40 days now around 70 for all heroes all 3/9 skills, but might already over 7k and raids success/resources avail really slowed, lvl up build/towers too fast. can get to 1500-2k in arena, in for $60 so far.
