Is there any way to keep the scenarios always clean?

I've noticed that no matter how much resistance I have (all 75% btw) or how high my HP and DEF are, I'll eventually get one-shotted by something off-screen without any warning.

The only solution I can think of to get around this stupid design flaw would be some option to simply make the effects of skills and dead people disappear from the ground so that the spells are much more visible and thus better avoided, in addition to the eventual performance improvement.

Is there an ingame option or mod for this? It would help a lot.

Yeah... U just run something that shatters enemies.... K bye
