I have it on my life, but I kinda want to restart my life character to give a better name
Wait for more responses that just mine so you get a few different opinions!
Personally I don't think Goat Monk is a big reason not to start over. I have it on my life and only use it occasionally when I am messing about and being funny with my team - it IS a funny-looking spell
If you want it on your new life wizard you can always craft it later. It's certainly not been an essential part of my strategy and is a 'just-for-fun' spell if I ever put it into my deck.
You probably know this but if you decide to delete your wizard remember to pass everything she owns to your other wizards through the shared back.
Goat monk can be decent, but I see more people using Luminous weaver as it is only a 4-pip spell and puts a -25% on the target. The only reason I suggest you keep goat monk is that it's a Loremaster spell; hard to obtain, especially getting the right spell on the right character.
But if you know this already and still want to restart your life character, by all means go for it. You CAN craft it later on, though difficult to do.
