SFX: Hermetic Ritual: If you have the time and materials to prepare and execute an elaborate hermetic ritual you may step up an Ability trait you are using Spells to emulate two steps for one action.
Limit: Lexical: Requires time and materials (spellbook, scrolls, etc) to change what other trait this Ability Set's Spells trait is currently being used to emulate.
Limit: Restrainable: You cannot use traits or SFX from this Ability Set if you are physically restrained and / or lack access to necessary materials. Gain one (1) Plot Point when this becomes a Complication for you.
Limit: Known Spells: This Ability Set's Spells trait requires the caster to maintain a list of other Ability traits they have learned to emulate. Starting out such a character can add one Ability trait to thier list, plus one additional Ability trait for each step of Smarts they have (d4 = 2, d6 = 3, d8 = 4, etc). Adding more Ability traits to the list is left to emergent gameplay but should be no more frequent than once per Session or so; making it the reward for a Relatively Difficult Milestone Goal is a good option.
