tips on defeating the shadow dragon Options

[Patrick_hindman]

hey guys i just need some tips in fighting the shadow dragon, here is how i've battled him so far...
Well i tried melee at first, but the dragon seems to have an infinite amount of protection from magical weapons on him, so i tried to kill him with magic which i managed to get him down to near death but couldn't manage enough magic damage to finish him off before he heals himself. So i would like to know if the dragon does have infinite amount of protection from magical weapons.

Perhaps it is due to the "spell shield bug" which appears sometimes, so you cannot breach him succesfully. I didn't encounter this bug ever in my game tough. He has no more than 5 or 6 (5 I believe) pfmws for sure. Remember that you don't need "breach" to kill his spell shield. A simple "secret word" will do, and after that he should be vulnerable to breach.
Try replaying the battle (reloading). If it was due to spell shield bug, it should work normaly.
