Im not good with the pictures right now. My vision is messed up......
Do you have any block all damage champs ? dymethia was who i used and screamed hard at this prick - trying to get the timing down to block the first wave of bombs. I believe (dont quote me though) a strong ally protect will absorb the first wave of detonating bombs. After that you have to kill him dead as dead ........
Something like Wurlim/Vogoth/Vizier to extend the debuffs should work out really well as a core of your team. Decrease accuracy from Wurlim should be super helpful here. Don't hate the idea of throwing in Septimus there, too. Key is to pump HP on your champs rather than defense and especially on Vogoth. If you can get resistance up on all champs, do that too.
I'm not 100% on the 5th one, but if you get the stats right I think that should do the trick.
