What are my options for a missing limb spellcaster?

[RamblinWreck]

I have a 12th level oracle of Pharasma using the Life mystery that was originally using a heavy crossbow with crossbow mastery. We are using the critical hit deck and a major NPC got the severed hand card. So now I no longer have a right hand. I am aware of the retrain rules and plan on using them, but if I choose to not use regeneration as a way to increase character development. What are my options with wielding a weapon and spellcasting?

Technically speaking you need a free hand to cast spells with somatic components. That usually gets glossed over. Fortunately you don't need a divine focus to cast spells since you are an Oracle. You could take the meta magic feat Still Spell to get rid of the somatic component.

You also might consider a clockwork prosthesis to replace the missing hand. You could also make a bargain with some outsider or spirit and acquire a possessed hand to replace the missing limb...or more accurately animate a hand to replace your missing one.

Demonic implants.

Get a new hand.

Home brew a Wizard Hook that works with divine spells.

Use Still spell to bypass the need for somatic component.

Unarmed combat doesn't require hands.

Not all divine spells require a divine focus, many don't (no DF), create a list and use those if that's an issue.

Create a unique spell with GM approval that creates a hand for you to use. Maybe extend the idea to create magical body part replacements i.e. magical prosthetics. They need not be permanent, obviously duration factors into level of spell.

Quickdraw might help with swapping between spell casting and weapon.

Get your GM to let you buy a prosthetic, use the prosthetic (or even specifically built to hold the crossbow), take your free hand off the weapon to cast spells.
