Dark Law: Meaning of Death/Magic

"Cost" is the cost to research a spell. After researching it, it can usually be purchased for "cost" plus 100 gold; see "buy:" notes for the exceptions.

In some cases, there may be more than one formula for a spell. The result is the same whichever you choose. The only case in which this makes much difference is with Thunderbolt, where one formula is somewhat cheaper.

There are also duplicates of Cure Poison and Earth Heal in the ROM with different MP costs (12 and 2 respectively), but they don't seem to be accessible to the player. All variants of Earth Heal (possibly cure poison as well) deal moderate damage to undead when cast on them.
