Antimagic disruption bug

[btonassse]

Hi, unless I'm really blind this is probably a bug.

I'm playing a Drem Wyrmic, currently lvl 8 and as soon as I started wearing an antimagic amulet, I got the arcane disruption warning and icon on my status bar. My char:

- Learned talents of the following talent trees: two-handed assault, sand drake aspect, fire drake aspect, storm drake aspect, combat training, call of the wild, fungus, drem.
- Three inscriptions: healing, movement and wild
- No equipment that makes me undead.
- The only arcane powered item I have is Wheel of Fate, but I was told in chat that this doesn't trigger arcane disruption. I also have The Which that Writhes, but taking it off doesn't remove the debuff.

When I put on the amulet for the first time I still had a shielding rune, but have since traded it for the movement inscription and the debuff icon remains.

So is this a bug?
