So with the slime casino back I wanted to bring an idea I've had for a while forwards, and that is a change to impostocubes. Currently they are a rare monster replacement - but what if we made them more involved during casino times?
Impostocubes would have a boosted spawn chance for the duration of a slime casino return - probably black kat level. Impostocubes would also be altered to always drop a golden slime coin. During a casino event, impostocubes would have a very rare chance (think: book of dark rituals chance) to drop a slime lockbox or a slime key.
This turns the seeking of a casino into a double game - one to find slime coins (more reliably), and another to find the actual casino and gambling there. We could even get dapper combos and toupees on the slime prize wheel to mimic the impostocube rare drops!
