I've been fascinated for some time with the idea of a character who can activate a multipower at will, but can only control which power by taking extra time.
For example: Marvin the Mage found an ancient spellbook. Due to the chaotic nature of magic, the spells rearrange themselves whenever he isn't actively looking at it. This could also apply to a deck of cards, or some gizmo with knobs to set or any other kinds of combinations.
How I see this working is that Marvin can cast a spell from the book just by opening and reading it. However, the spell that he reads is randomly determined could be the 10d6 heal... could be the 5d6 RKA.... However if he spends a phase (extra time) flipping through the pages, he can find the exact spell he wants.
I want the character to have the option of randomly pulling a power, so that in an emergency he can just toss something out which will either help or hurt their situation. Perhaps 9 of the 10 spells are attacks, but the other is a heal or aid etc.
I'm just not sure how to make the control conditional. No Concious Control doesn't quite fit, nor does Side Effects or Extra time. Any ideas?
