the corrupted you are trying to kill has 2016 of power. the champion level 10 you sent i think has arround 1457 of power

so ur champion is not strong enough to kill the corrupted

always take a look on the power of the corrupted and the choosen champion to send. if this last is not strong enough go to undead section to kill some of the to upgrade ur champion to the power of the corrupted and u will kill it.

hope this can help you

Hi, there is something I don't get: I sent a green level 10 champion (+1 in Enlighten) against a level 7 Corrupted in league tower and... 

A level 10 Champion can only kill level 5 undead and corrupted, but you attacked a level 7
You need to use level 13 Champion or higher

Also, Killing corrupted on Floor 31 is probably a complete waste of time and energy - no more rewards until floor 35 - then 40

I usually stop at floor 30
