You can shoo him away and he will go wait for you at lady vengence (not sure where he goes if you shoo him in act 1).

I absolutely love his inclusion, but i was not opposed to shooing him for periods of time due to his annoyance in combat and traps.

He added something very sweet and tender to the game though. My first playthrough I didnt have petpal. My 2nd, I did, and his little side story / personality just added a really cute touch to the campaign.

Anywho if hes annoying Id just shoo him away if i were you

I actually would find the shackle thing to be a reason NOT to keep him around. Since it's gimmicky and not your strategy that did that but some random thing.. not my cup of tea. I dont mind that sir lora was chosen as a shackle target, but the fact hes out of combat and keeps healing, just seems like an easy unintended "win".

Also, if you permafrost the black ring folks itll drop shackles.

Cheers!
