While playing the Telvanni agent fighers guild quest, i found two amulets. The graveward amulet and the amulet of shades.
One is supposed to summons a skeleton
The other one is supposed to summons a zombie, (Of course there are no zombies in morrowind so it must of been changed from bonewalker during the conversion)
Neither one of these amulets actually summons anything. Hopfully this will be fixed.

Test esp for ya
Ok, I've had a look at this and found that the spell effect (in this case, 0summonSleastSbonewalker for the Amulet of Shades) works fine as a potion, just not when applied to an amulet. However, I've tried it and it will work if we use a modified version of the script: 0AAMWFiendTantoSCRIPT.
I've uploaded a 7zip archive here containing an esp file that adds a script for both of the amulets (also included as text files). Please can you test these and see what you think?
Right, bedtime for me. It's my stag do tomorrow (we're going paintballing).
