Infinite Damage, Meet Mudrock

Fortified Pass, Pyrolysis Map 1, Max Risk Defender Only
This map is pretty hard for Defenders because it comes with -70% HP down and all the enemies have really large attack. In particular the stealth leaders deal over 10k physical damage, which with -70% HP requires almost 30k HP to survive, which is impossible. Horn S1 doesn't work here because she won't fire without active targets, which means I had to reveal the leaders by blocking somehow.
Thankfully there's a lot of damage shields in Defenderknights like Nian, Mudrock, and Blitz's stun can also keep them visible. Probably the first map where I think the sentinel Defender mod effect would be huge, but we don't have them on EN yet.
