Using d2 1.13 and latest (Nov 27th 2014) Ultimative XVc
Sunstrike: Tends to not hit target. I have to aim off-center of target to hit it when I fire 2, 4, 6, etc arrows.
Lionheart: Recasting this spell does not refresh the duration.
Disenchanting: Doesn't work on some dropped items. Seems to be linked to socketing, as some items were previously socketed and used but sometimes this doesn't matter and it DE's them anyway. All items in question are fully repaired.
