My current group includes a cleric, a magician, and a priest. The cleric is doing a good job at the side of the fighter and the magician made the choice not to cast his 2 spells until it's a real emergency. The priest has more spells per day, but his spell list has only two spells with which he can directly participate in combat, command and magic stone. And a single attack at +1 to Hit and 2 damage doesn't seem much  better than attacking with a sling or dart.
The issue kind of solves itself at 3rd level when priest and clerics get access to darkness, hold person, weird warhammer, and wyvern warden, which are really quite good ones.
But at 1st and 2nd level a priest is a 0th level guy with a sling and healing potions. The priest in our group had a few opportunities to make use of his religious education, but we do have a significant amount of dungeon crawling.
I'd like to offer the player 2 or 3 offensive spells to give him more room to participate, as I think he's actually one of the most invested players in the group. Any ideas what spells would be suitable?
