I am experiencing a bug quite regularly where hammer throw stops spawning hammers.
I cast the skill, it plays the animation, it consumes the mana but no hammers spawn at all, and as a result it does no damage at all.
It happens randomly, it just starts and then it’ll fix itself after a while. It’s even happened to me while standing around in a hub talking to vendors.
Also happened to me when skilled Disintegrating Aura. Also the passive with thrown axe on sentinel tree started procing without having it set again when skilled the aura node, maybe i should report it as separate bug.
If you aren’t getting hammers thrown anywhere with the disintegrating aura node then that would be a new bug. If you’re only having issues in specific areas then that’s most likely an issue with the area you’re in.
Edit: Regarding the throwing axe, there’s a pair of unique gloves (Riverband Grasp) that also gives you a % chance to throw axes.
