I'm running a Pathfinder campaign with the Eberron 3.5 setting, and I'm often finding that I want my players to be able to use magic in a way that the rules don't allow.
For example, a party is in an area closely linked to Fernia (the fire plane) and it is reasonable for them to find a way to pass through, without casting plane shift, but with some cost.
How can I model a cost for any spell like effect that makes it accomplishable for the lower level party, but has a similar resource requirement.
By resource requirement I mean that it should diminish the parties resources (mystical, material, whatever) by some amount roughly equivalent to casting the spell. These effects are largely plot driven, but occasionally the players will ask the inevitable "Can I do X", and I'd like to have a way to figure out the cost to them.
The ideas I had for resources that could fulfill the cost:
- Spell levels given up
- Action Points
- Hit Points
- Material Components (essentially monetary cost)
Does anyone have any experience modeling characters producing effects beyond their normal capabilities?
It was asked how the existing spell services, scrolls, and other items don't fit my needs. Services don't make sense because I intend for this to be something the party can do. Scrolls don't make sense because these activities don't require preparation or an item in particular (Note the beginning says
in a way the rules don't allow). In system terms I'm looking for something like you might find in a video game when entering an area that says "spend X here to do Y", thematic magical options for characters in a scene.
