Necromancer update: So far still no luck on any weapon skills, of the utility skills i've tried the closest I have gotten is Signet of Spite. However upon any movement, you de-sync once again.
I have had better luck with underwater skills, #3 Skill on Trident called Foul Current correctly syncs up if used right after TP.
I will try later with Spear once I unlock the rest of the skills.
Edit: Spear has no ability's that allow a resync after TP, looks like Foul Current is our one and only way to sync up. Guess I'll have to make sure to always TP from an underwater area.
Also on the guardian side, noticed you have savage leap as one of the skills, just to make sure, that's a warrior skill.
The guardian Greatsword skill #4 Leap of Faith does indeed sync though.
