Since the Mana Sword cannot be acquire by normal means unless Mana Magic is cast on Randi, the spear can be the second best weapon since it is quite common to find Tsunamis in the Mana Fortress. The chances are increased since Tsunamis multiply. The attack, along with Randi's default attack, make it a suitable weapon for him.
