One Arm Caster Help

[Kalan Tel]

Hello, I am playing a sorcer/cleric/mystic thurge, we are playing Wrath of the Righteous so i am mythic. I am 1 lvl sorceror, 3 lvl cleric, and 6 lvl mystic thurge right now, Mythic level 3. straight caster no weapons at all.

Now that you know my character, my dilemma is that my one arm had recent been lost, through an acidic explosion of sorts, which leaves me in a predicament. I know I can cast with just one arm free as a caster so thats not the issue. The main issue is that I possess a legendary artifact called the paupers thighbone, a sort of rod used for metamagic feats, which I must hold in my hand to use. Except I need a hand free to cast spells. Now i already have Still spell as a feat, but the thighbone allows me to use my meta magic feats without increasing the spell level. So there would be no reason to use it at that point. (until I get maximize spell and the like)

Now the question is, is there a way for me to use the rod while still maintaining my one remaining hand free to cast spells? Whether it be some way to magic hold the rod and cast it, or something of the like.

I was thinking mage hand or something of the like, telekinesis maybe, but i must concentrate on those spells and then cannot cast a spell while concentrating so that went out the window.

Now i realize I could get my arm regenerated but at the time it is not possible. (plus it plays a really interesting twist to my character and back story)

Thank you all for responses.

Could you polymorph into something with all its arms and/or something with enough arms that you end up with 2?

The Regenerate spell should be affordable at your level (1,365 gp standard price) and available in any major metropolis for the standard price. (A metropolis should have access to 8th level spellcasting services and regenerate is only a 7th level spell. Granted, I don't know the local setting of the Wrath of the Righteous adventure path.)

Well, since's there's no way in straight PF you can lose a limp like that, why not play it that you use the rod as your Somatic components, like Happy Potter?

You wave the rod in a special way.

Is your whole arm blown off, or just your hand?

Wizard Hook. It's awesome.

Make it intelligent.

In a similar vein: If I had a character who lost an arm, would you consider it to be appropriate that they have a 'magic prosthesis'

It has no more or less functionality than a normal arm?

I have an idea for a fighter-type who lost an arm and now has an armored prosthesis that attaches to the shoulder/chest and allows her the use of the arm enough that observers might not even notice until they removed it.

Use Alter Self before casting so you two arms. Just don't take the bone out until then.
