Really a subset of the previous point, but it happens so often… Don’t try to play a ranger like a warrior – rely on the bow! Similarly for mages, don’t do a Gandalf. He may be able to draw a sword and rush headlong in to a pack or orcs, but mages in Angband are considerably more fragile. Priests are better equipped to engage in melee combat – with their healing abilities compensating for their somewhat fragile nature.
