So I just got Ruin back to following me after he left during a night, but I haven't got the spell to summon him back. Which is a right pain as he's randomly vanished when I fast travelled and now I can't find the bloke.

Anyone know what the spell ID is for the spell and the console command for adding spells?

Don't worry, the spell is supposed to be gone now. Make sure you read any quest updates you have, and just be patient. :wink_smile:

nvm, continued on and Ruin spawned next to me and I got the spell back. Beaten the mod now and while it was good I got annoyed when 2 of the NPCs in the last encounter I killed counted as murders which kinda ruined my 'good guy' image. 'specially when I got arrested by a guard when I left the well. Hoping I didn't get booted from the fighters guild or anything...(Had to use a console command to get rid of the infamy)
