is better drop on move catacombs or can i stay and click t , ?? thx

It's debatable, in theory with it being an RNG game, mobs per hour would seem to be the correct answer, however harder monsters (move catacombs) yield a higher chance to drop same-higher tier items.

The answer to this question is:

What drops?

Drops are random and pretty rare.
You find EP's exploring and they have a better drop rate.

high lvl magica, i drop most white items
