In endless mode after you beat each set of wave (the number next to the skull) it starts again with 2x the HP of the monsters.

Kills in endless mode are counted for the current Dilboom event so doing that got very easy. They also lowered the required amount to 15k.
Didn't realized that was a possibility, i can't look at that map right now.

The rewards for the even was a little weak too.
