What's wrong with this battle?

[OG_Gleep]

There are lots of ways to kill an ice devil. Ice Devils are classified as SC's, and there is a very recent thread on magic vs SC's. 20 resistance doesn't make them immune to spells.

What weapon is the athame. I don't recognize it and I couldn't find it in the magic item list.

The Naj has the ability to conifg a lot of different ways weapon wise. If the Athamme doesn't give fire protection, the dragon scale armor won't give 100% resistance to fire, so you could use any of the multiple fire weapons.

Vine Shield/Eye shield could also work.

And as Oversway mentioned there are a few +demon weapons that you could use. The flambeau does fire dmg + 3x dmg to demons. You could use 2 of them, 1 + weapon + shield or 1 + 2 weapons.

Also, why not use more of the buffs you have available?

A3 has Mistform and Mirror Image
S3 gives you access to Astral shield and Body Etheral
W2 gives you access to cold resistance

And if I'm not mistaken Naj are cold blooded...you could be going in with a stacked deck if the province your fighting in is cold. Not only does it effect you, but it buffs ice devils.

Anyhow, Ice devils are great, but theres a ton of ways to beat them.
