"Nisch" gnolls are always clerics. You should almost always attack them first, and try to keep them stunned so they do not heal. An enchanter is very useful because they can mez the other mobs while you kill the nisch.
Lvl is all wrong i have hunted in Split-Paw for a long time and they con red to me at 29 so,they are not 30 and there are no gnolls in ther with Split-Paw in them!!!!!
