I know this question is probably answered elsewhere but on a recently playthrough (with a dwarven paladin) I was crowned N= with Aylas Holy Scarf. Then late in game I (extended) dropped some stuff on a chaotic alter after I thought I had converted it. I ended up with all cursed equipment. Strangely though the scarf remained blessed.

Is the crowning gift permanently blessed or is that a property of Aylas Holy Scarf? or can the other gods not curse it but if I dipped it in unholy water it would become cursed? I forgot to test this.

Unrelated to the question but I accidently dipped my scroll of uncursing in a potion of strength instead of holy water and ruined both. Leaving my equipment cursed and short a strength point. Sad times.
