NO loss first island tips!

[badsector]

Hello. I managed to kill Ahriman and the necromancer in the cave without losses. But I have serious trouble with Eric. He has the poison skull magic and kills something every time he casts it even though he has only 2 intelligence. He casts it several times during the battle so there is no way to resurrect the casualties. I don't have a nature call scroll, only 2/3 soothsayers, one healing scroll and some other offensive scrolls. I'm playing a Viking class. Any ideas?
