As discovered by Defaault on reddit, there is a bug where all equipment on a character will disappear if the character is wearing Strand of Favor and is hit by the spell Form of the Helpless Beast.

The above video uses a modified version of Form of a Helpless Beast to demonstrate this, but otherwise this bug is vanilla behaviour.

From what I can tell it seems to be caused by -10% Hostile effect duration from the Ward of Favor enchantment reapplying as the spell wears off. I've test a few other items that do reduce Hostile effect duration and Arcane Containment on Cabalist's Gambeson is the only one I have found that also causes this bug. Things like Lone Wolf on Ring of the Solitary Wanderer seem to be safe for whatever reason.

I noticed this too, but I never figured the cause. I thought it was a bug intresic to Form of a Helpless Beast so I avoided this spell like plague.

After a bit more testing I'm pretty sure it's only items with itemmods that are applying the "-x% Hostile effect duration" directly as a status effect that can cause this bug. Which would explain why itemmods like Lone Wolf that apply the status effect through an ability won't trigger it.

Good to know, esp. vs Nemnok goons.

What happened to me was Ikorno delete my headgear enchants at the end of the battle... and with Rekvu's Fractured Casque that was not really funny 😄
