well if you want to make it as a 3rd pet or something.. you can script it into the mirguidebook.. so when you press D, it automatically recall's the pet near you, if that doesnt work.. you can use killslave and just make a new one each time lol.
but from experience the monai pet's are a bit buggy.. and they sorta freak out.. alot, granted, you have to pull out alot of the usually monai's commands.. like the jumpto or recall, id take out clearstatus aswell. and leave out multiple strings of monai's and just keep it basics, it wont bug up as much.
and as far as i remember.. you can still use fw and such.. it wont attack you and its spells wont hurt you.
