Just a quick thought about a looser spell design move for Wizards.
When you (carve a rune into a surface | invoke the ancient powers by song | call up magic by word and gesture) roll+INT. 10+ Choose 3 from the following list. 7-9 Choose 2 and the GM chooses 1 from the second list. 6- Ouch. You may add an additional tag from the first list by also choosing an additional tag from the second list.
Forceful, Messy, Silent, Subtle, Area, Ward, Elemental (type), Necrotic, Illusion, Ongoing, +1 Forward, +1 Ongoing (to a narrow set of circumstances), -1 Ongoing to opponent (to a narrow set of circumstances). Near, Far, Piercing, Stun, Damaging (deals 2 x class damage), etc.
Loud, Attracts Attention, Exhausting, Slow, -1 Forward to spell casting, -1 Ongoing (to a narrow set of circumstances), Debility, Spent (this particular spell is used up for the day) etc.
For additional colour, choose one from the following list: Divination, Enchantment, Illusion, Summoning, Evocation, Necromancy, etc.
If relevant choose the spell type: Missile, Shield, Circle, Wall, Touch, Eye Contact, etc.
Example (for Tim Franzke )
Wall of Fire (Wall, Summoning): Ward, Elemental (fire), Ongoing. Deals class damage and produces a wall of fire.
