According to Vetron's Guide to Weapons and Armour, the magic axe has an effectiveness rating of 8, and it is noted that it can be thrown.
They first appeared in Ultima IV, where they were sold in Minoc. They were slightly less expensive than the magic bow, yet slightly more powerful. Only paladin and tinker characters could equip the magic axe.
They could be found in Ultima VI as loot.
Magic axes were quite common by Ultima VII. The best source to find two of them were the pair of skeleton guards in Horance's tower in Skara Brae. However, the axes had lost some of their potency by then.
- Throwing axes are also found on the Serpent Isle, and can be bought from Pothos in Moonshade for 600 Guilders each.
