I'll keep my eye on how things go with more Redemption monsters and if it does end up becoming an issue then we'll figure out how to adjust things.

As for the order of effects with things like earthquake and blast, I am working on an update to the battle system to make sure that all damage is applied first and then any deaths will be resolved afterwards. So that way it doesn't matter in what order the damage is applied, which is how it's supposed to be.
