Issue:
XAN rune does not reliably activate and provide the guaranteed Overpower & Critical strike.
Context:
Necromancer Using YUL rune to fuel offerings to activate XAN rune for Overpower Critical hits to Soulrift while wearing Unmaker Helm.
What should happen:
With YulXan equipped, I use Bone spirit to provide 50 offerings 16 times to fully charge (800) Xan rune, then activate Soulrift. Subsequent shadow damage dealt from wearing Unmaker while using Bone Spirit is Overpowered and Critical hits for duration of Soulrift.
What actually happens:
As described above, BUT when Soulrift is activated on a fully charged Xan rune all subsequent shadow damage dealt via Bone Spirit/Unmaker is unmodified by overpower. It is critical hit damage, but character has high Crit Hit chance so it maybe from that source and not the rune.
Additional details:
(1) This rune combination and gear setup WAS working correctly and reliably using only Bone Spirit as the offering generator every time prior to this. No changes that I am aware of were made to character prior to the rune not working correctly. The shift from rune working to not working happened while logged in and playing the game. Note: results are the same whether I am activating a Xan charged Soulrift while a soulrift is currently active or not.
(2) After many, many, many attempts in the dummy training room using every recombination of gear, runes, aspects, activation timing and even active follower, I found a way to make it work. With Yul rune giving 50 offerings per use of a skill with cooldown, charge the Xan rune 15 times with Bone Spirit (my builds damage initiator) and then use Corpse Tendrils (has cooldown) for the 16th skill and final 50 offering. Initiating Soulrift at this point activates the Xan rune correctly and all shadow damage dealt for duration of Soulrift is now Overpowered and Critical hits per description.
Conclusion:
While the work around of using a separate skill to correctly activate Xan rune does work 100% of the time now, I don’t believe this is how it was intended. Especially since previous to this, it was working off using Bone Spirit for all charges and only stopped working that way for no apparent (to me at least) reason.
Edit: Clarify wording.
Edit: P.S. Recommend rune charge indicator on buff bar change color to indicate fully charged and ready to proc on next offering. This would be extremely helpful when trying to time casting a specific skill/action with the proc availability in the heat of battle, especially if offerings are relatively small.
