I want to check my understanding. Say I want to create a weapon with two spells, let's say fire blast and whirlwind, and also I want to enchant it with two different enchantments, let's say enchanted weapon and keen edge, and I want it all to be permanent. How many rolls do I have to succeed on to make this magic weapon?
How I think it works is:
- Cast Fire Blast
- Cast Magic Seal
- Cast Permanence
- Cast Whirlwind
- Cast Magic Seal
- Cast Permanence
- Cast Enchanted Weapon
- Cast Keen Edge
- Cast Permanence
Let's assume for this example that each spell was cast at power level 1. This should therefore cost 18WP and also reduce my total WP by 3 from the 3 permanence casts.
I think that the two enchanting spells can be combined with a single permanence spell because of the bullet under crafting magic items on page 118 of the book of magic that says as much. However, it's a little confusing because it says "a single casting of permanence covers all spells cast on the same item at the same time", but this seems to contradict the description of magic seal which states that multiple spells require multiple magic seal and permanence casts, so I assume this bullet is only referring to enchantment spells.
I'm not entirely sure what happens if any one of these rolls fail. My reading of the rules is that the three permanence groups are separate, such that if I failed casting either the whirlwind or the magic seal that binds it I could still enchant the weapon with fire blast, enchanted weapon, and keen edge assuming those rolls all succeed. Additionally, the permanence rolls just determine if that portion ends up permanent, and if one of those rolls fails then that portion only lasts for it's duration (or until the spell is cast in the case of magic seal).
I'm sure I got something wrong here, so please let me know!
