There, I almost lost: on level 113, I barely made it to the exit of my zone by fighting only gargoyles (and I ran with just one hero to that exit, picking up one gargoyle along the way), and then I ran into a block of 34 gold mines guarded by water elementals.
I came out of the battle with 26 grams.
Level 113, no rests, and my zone was already cleared (they're small). What should I do in such situations?
