So instead; I boiled down Wizards without the above to create the most generic and traditional suite of powers I thought fit the Orthodox Wizard;
- Create/Control Arcane Energy
- Animate (Inanimate) Objects
- Discern the Invisible or Hidden
- Levitate/Hold Beings
Create/Control Arcane Energy is a good one; as it fits with things like magic missile, prismatic spray and wall, and fits with all other evocations and generic Wizard spells that aren't tied to elements.
Animate Objects is one that's very fitting, in my opinion. I think of Wizards as from Disney, such as Mickey Mouse in the Fantasia short, or the Sword in the Stone's Merlin, or even Beauty and the Beast's anthropomorphized objects as good examples of what I'd consider an animated object. Not just floating around, but also not totally humanized either. I see the “Animate” keyword as to mean giving human qualities, not just motion, so I see spells like Magic Mouth and Alarm (when an object is moved) also counting towards the animation, which is classic Wizard stuff.
Discern the Invisible or Hidden is a tougher discipline. It's very classic of Wizards to learn the passcodes to secret doors, like Gandalf, but may step on player skill and classes or characters that specialize in secrets and lore. Revealing the invisible at least is pretty obvious; faerie fire or glitterdust are classic examples- along with the Corona spell from dungeon crawl stone soup, though technically that's for Enchanters in that game. As an aside, one of my favorite things from Harry Potter was when Professor Snape commanded the Marauder's map to “reveal its secrets to him”, as though this is common practice to reveal invisible or hidden things, simply throwing around your Wizardly authority.
Finally Levitate/Hold beings is a classic among Wizards. While “levitate” implies a calm and gentle motion, it doesn't imply flight, which is a good start. However I also like to imagine it being able to used as a quick slam or shove, such as to throw people off a cliff or off horses, which is pretty fitting to a non-elemental Wizard's combat potential. Hold person/being is also a classic of Wizards.
There- I think this list of archetypal spells is very well fitting to a non-elemental and generic Wizard. While very specific, I think it helps give personality to the class without being an “everyman”.
