Shaping First World with Charisma Check, DC’s?

[Oli Ironbar]

I’m considering the different planar traits as a roadmap for what changes could be made to areas of the first world, if only temporarily.

What range of DC’s would you consider for all of the different planar traits covered in the create demiplane spells? (From changing mild alignment, to altering the shape of a combat area so leaving one edge puts you on the opposite side, to altering the flow of time and enhancing/deadening magic.)

Starting at DC26 .... And every 5 points up something more.

More importantly to me, what a great idea for adventure dynamics in The First World!

I that really high starting DC.

I love the idea of fighting in a forest then turning on subjective gravity in order to run along an upright tree trunk to fight an enemy 30’ in the air. I’m also hoping to make it a team effort with a few mcguffins too, either to aid or spend spells to aid.

My opinion for a high DC is based on my feeling of the difficulty in changing the landscape on which you're adventuring.

But if you create a chart or list of examples, in order to get an idea of what can and, more significantly, what *can't* be done, you could start at DC 15 and go up every two or three points from there.

And this also depends on your group's gaming style. Like, I don't think my group would get to something like this until at least 14th-15th Level. And by 16th Level, with our Ability point-buy and magical treasure history standards, one PC already has a +10 CHA mod and a second or third PC will have a +6 or +7 CHA mod. Your games may be different. Or your feelings may be different

Ooh, you can look at the Illusion spells for ideas of what to allow, how to gauge or direct. What one can do with Silent Image, Major Image, Hallucinatory Terrain -- perhaps the Shadow Conjuration spell -- and spells like Make Whole, Move Earth, Guards and Wards, Repulsion -- all kinds of stuff as a guide to see what can be done with a CHA check.

Assuming you want shaping effects to be common I would first work out which spell on the wizard spell list is closest to the effect you want then apply the formula:

DC = 15 + 3 x spell level.

I would rule that a 10 minute ritual is required to use a shaping effect unless the PC spends a mythic point to reduce the time to a standard action. I would let characters spend an additional mythic point to use mythic surge on the charisma check too. I would also let some types of luck bonuses apply to the charisma check, even if the rules wouldn’t ordinarily allow it.
