After multiple deaths over 2 hours against Wavecutter in the Blackheart dungeon and finally giving up, my group of friends and I are trying to figure out a few things about interrupting and blocking.
Does something like Shield Charge, which normally does an interrupt of a caster when it does a knockdown, still do an interrupt of a boss even though the boss is immune to knockdown? Ditto Stone Fist, from the Dragonknight Earthen Heart skill line? I'm the tank, but I'm not fast enough at interpreting graphics to pick up on the tells every time, so we are looking at ways for others to help interrupt.
Does anyone know if the Forking Bolts (purple bolts from Wavecutter, hit multiple people with very high damage, about every 10 seconds) count as Projectiles and can thus be blocked with Reflective Scales or Defensive Stance? They look sort of like projectiles, but hit everyone in the group, so may count as an AoE, hard to tell in this game.
