Research a brand new arcane spell with the same effects? All you need is a sympathetic DM.
Independent Research: A wizard can also research a spell independently, duplicating an existing spell or creating an entirely new one. The cost to research a new spell, and the time required, are left up to GM discretion, but it should probably take at least 1 week and cost at least 1,000 gp per level of the spell to be researched. This should also require a number of Spellcraft and Knowledge (arcana) checks.
There are three main ways to get a spell from another spell list onto yours.
Samsaran (race): The spell list you steal the spell from must be the same type (arcane or divine) as your spell list. Command is on the Witch's (arcane) spell list so you can do this.
Improved Eldritch Heritage <Arcane> (feat): This will only allow you to steal from the Sorcerer/Wizard spell list to add to your spell list. Since you are a Wizard this will not help you.
Ancient Lorekeeper (Elven Oracle Archetype): This allows you to add Sorcerer/Wizard spells to you Oracle spell list. Not helpful.
Unfortuntely, I think you are out of luck.
BUT there is hope, Riuken suggested a reasonable method. Get a Staff with the spell Command on it. Have another spell on it that is on your spell list. Then you can use Command at your caster level and with all relevant feats and ability score modifiers.
The general guidelines for researching spells is to try to maintain the general distinction between arcane and divine magic. In some cases that might be interpreted by a GM as the spell not being possible, but usually it means the spell can be researched, but it becomes a higher level spell for the "other" type of magic.
So "command" researched as a wizard spell might be a second level spell instead of first. That's how I would rule as GM.
Thanks all. I figured it was a long shot. Unfortunately it is a Society character so spell research is out. I may in fact buy a staff of rigor or take a few levels of pathfinder savant. I am not big on the latter and it sucks to wait til 6th level (when I have enough prestige) on the former though. Oh well, my enchanter will just have to do without.
Does anyone know if a ring of spell knowledge could do this?
I am a wizard 2 sorcerer 1 and though the item says it is only useful for spontaneous spell casters, does that mean it can be used by no one else?
Can I use it to add command to my spell list and then roll a spell craft to put it into my book (where all my real skill is)?
