Everyday Spell[]
In some fiction, you have spellcasters of sufficiently high power or skill casually using magic for everyday whims; for example, warming or stirring a cup of coffee. GURPS standard rules optionally allow this if the spell is known at a skill level of 15+ (GURPS Magic p.8-9). This has two unforeseen (and usually unwanted) effects: allowing IQ 14 Magery 3 casters to do this using spells with which you haven't gone into great depth, and rendering this ability out of range of your typical IQ 12 Magery 1 hedge wizards. However, if you link the Fatigue and Ritual reduction to Effective Skill rather than Base Skill, these Hedge wizards can pull it off with a Task Difficulty Modifier for "non-stressful everyday usage" (+4). Furthermore, Wizards who attempt really tricky uses of their spells will have to put more effort into them.
