Uh...Masterful Kill stuffs almost any attack in the game. It's not just a damage mitigation tool, it's THE damage mitigation tool.
Additionally, Back Kick/Escape Onslaught have a whole ton of i-frames. It's what I use to kill Ogres in the quarry at a ridiculously low level.
More BBI stories, I killed the second boss solo (now at like L76) and now I'm in Rotwood Depository where they're REALLY trying to kill me. XD I found two chests with more Everfall weapons (still no Dragon's Pain, goddamnit...) down where the Eliminator and undead mages are. These seem to have Dragon's Quickening, Dragon's Risen, Dark Buckler, and Frigid Finger.
Again, if anyone finds a chest with Dragon's Pain in it on BBI, let me know. Even Dragonforged, my Bardiche Daggers are showing their age at this point and the Chilling Razors I got from Lv.1 Bitterblack Weapon aren't much better. I really, REALLY don't want to have to go all the way through the main game for an upgrade on them when pretty much every other weapon type has popped up.
