San Tojalon is one of the long-dead warriors the player must defeat to collect the heart piece for the Legends' Quest. He attacks with melee and can only be killed once, twice if players chose the "short" route in the quest. Also, killing San Tojalon causes the rest to stop being hostile.
There are several San Tojalons in the Kharazi Dungeon. If players want to conserve food for the fight with the demon later, they should use Protect from Melee since the demon will drain the player's Prayer at the beginning of the battle anyway.
