Barrage chain is sufficient #hits to make a decent CoC setup...now try LS GMP LMP chain with the +1 chain in weapon. Probably multistrike too, and LoH. I should probably make that setup anyway. Kill nothing, but projectiles all over the screen ought to be quite amusing. That or I could go curse on hit...
To keep with the theme, obviously I'd use storm call! but practically speaking, arc/spark might be better use. For anti-reflect purposes, LL gem. Double up using two of these maces for maximum lulz.
My prediction is that Mjolner will end up in the 1-2ex range in any league which actually matters (read: not SC.) That's pretty much the going rate for an endgame unique gimmicky weapon. Isn't it interesting how certain prices always settle at certain rates? Looking at you, Dream Fragments. But in any case it'll be affordable enough by the time I reach that level. If I reach that level. Path of Rerolling FTL.
The proto-build in my phone memory (I use the skill tree planner app) is
labeled THammer. Bit of a legacy from my Fire Emblem days, love those
games. The build's short about 100 each of str/int directly from passives at 90 points. That means Astra, or more likely it means I'll hunt down a statball amulet. Statballs are hilarious in addition to being frequently useful. And why do templars always need to take a roundabout route out of their startzone?
