Reassigning prodigies

[Fhtagn]

Is there an addon, or, failing that, a debug mode command that will allow me to unlearn/reassign a prodigy point?
For some reason, I seem to have selected a prodigy I never even considered taking, even though I am sure the right one was green when I closed the prodigies window. Well. Brainfart, I suppose.
I only realised one level later. Considering I am playing a doomed build made for mental tyranny and I am working on a guide for that build, not having it would be... unfortunate.

This will invalidate your save, but you can try enabling developer mode and copying the following into the Lua console (CTRL+L)

game.player:unlearnTalent(game.player.T_SPINE_OF_THE_WORLD)
game.player.unused_prodigies = 1

Thanks! For the purpose of writing that guide, I don't care too much about invalidated savegames.
