"While playing on Elite difficulty, they are MUCH more likely to revive other menders. And by much more likely, I mean they will revive each other the instant one dies. This is extremely annoying in an arena situation, where the two menders are often blocked by Mecha Knights or other monsters that form a solid wall, making them hard to reach; when you're able to kill one mender, the other (whom is probably at full health due to you focusing one mender) will dash over the moment his pal dies and revive him."

This is where the Final Flourish's charge attack saves the day ;)
I don't think this is a complaint thread, but in case it becomes one, let's not make OOO think that we need more nerfing.

This bomb is the solution to any arena that is not poison themed. It will also work in any gremlin-heavy arena, since gremlins have no status immunities.
