Blade Breath now works fine, but the Impale DoT barfs up a lua error every turn it ticks:
I started doing insane damage and wondering where it came from and then I realized that the +phys damage provided by Blade Aspect's wound mechanic was being added permanently by the bugged Impale:
(after a few breaths without noticing until I began to wonder why I was bumping for 1400)
The bugged physical damage makes the character largely pointless to continue, but the Impale bug is indeed fixed. I'll see about getting around to starting fresh sometime, but initial 1-30 impressions are that Sand/Blade builds are quite strong with fantastic AoE and single target.
Installed newest version, broke my Fire/Storm mindstar yeek. Note on the lightning tree: Jitter and Rapid Strikes have pretty strong anti-synergy, sadly, since you need to keep hitting your target, but Jitter will very likely move you out of melee range.
Perhaps, while Rapid Strikes is up, Jitter could always move you to a tile next to your Rapid Strikes target.
The tree also seems to be the weakest for the purpose of equi regen: With fire, you have Burning Rage and lots of DoT, ice has retaliation, and unless a mindstar user, you'll do physical all the time for sand.
EDIT: Okay, so I made another Yeek to play around with Lightning Aspect some more, this time in the arena. 2-hander, ended up using more Sand and Blade. Crazy amounts of physical damage. Also a bug: Sand Vortex can hit targets twice.
