Spiritual mages commonly drop various battlestaves that are floored in the Grand Exchange by their alchemy prices (9,300 coins each). They also have various other drops that are worth modest amounts of coins. Battlestaves and rune items do not come noted, so it is recommended to bring magic notepaper or High Level Alchemy runes to keep inventory space clear. The best location to fight spiritual mages is the first room of Saradomin's encampment. This requires level 70 Agility. If not available, then the spiritual mages just outside of K'ril Tsutsaroth's room are a good second choice.
