Dungeon World / Creating new spells
« on: April 17, 2013, 05:42:16 PM »
One of my players wants to make his own spells, so we're working on some moves for that. Here's what we've worked out so far:
When you cast a spell you have not mastered, discuss the particulars of the spell with the GM, decide what level the spell will be, and roll +Int. You may only attempt to master a spell of a level you can currently cast.
On a 10+ You cast it no problem, and hold +2 Mastery.
On a 7-9 you cast it but the GM gets to modify the spell in some way: Range, Effect, Targets, etc. The spell goes a little wild. In addition you hold +1 Mastery.
When you attempt to master a spell, take a few hours to commit it to your spell book, and spend your held +Mastery. When +Mastery spent is equal to twice the level of the spell, you may add it to your spell book. You may only hold Mastery towards spells equal to your Int modifier.
So if you have +2 int you may hold mastery towards two separate spells. If you'd like to start mastery on a 3rd spell, you must release the held mastery, erase the spell and replace it with the new one.
You may also gain +1 Mastery by:
Spending time in a place of power, studying your spell.
Asking beings of great power for understanding, at a cost.
