Dancer's Axe (really wish they'd fix how much of a pain it is to "fight" the jars for gold loot drops!) was my 1st & only level 27 weapon...seems to be almost everyone's with the occasional exception of the best 27, Bosun's Blade or 1 of the worst being either of the swords. Interesting...
Andruil's Gift has been my first 27, thank the RNG Maker. Bosun's Blade is the one I most want, though.
Use an ability vs jars that doesn't trigger a cooldown when not hitting a real enemy. But yes, jars have the highest natural evasion rate of any enemy in the game, so you have to choose a skill with 100% accuracy bonus...
