The Fade proc occurs only once. After this the Merc is locked in faded animation but no longer has the Resistance buffs and will never get them again in that game. Once you see your Merc permanently faded, try removing the Treachery and his resists no longer change.
I guess it is possible that the bug is simply the Merc being locked in the Fade animation, I am not 100% sure, sorry.
When Quick Cast was added, Blizzard left one of the most glaringly stupid things about Paladins in the game… their Aura must still be on RMB to be active. This has given rise to a Quick Cast problem for the class. If you Quick Cast any skill via a KB shortcut, that skill is then left on the RMB and thus kills your Aura. Useless.
Every other class, when you Quick Cast something, it immediately puts whatever was on your RMB back there as if nothing happened.
I have several items that have a chance to proc certain skills “on striking”. These never proc with Druid’s Fury or Amazon’s Strafe, which surely count as “striking” the enemy?
Thanks for these Ghostlight,
but you need them through the appropriate channel. More info here: Reporting Diablo II: Resurrected Bugs - Blizzard Support
