Here, here!
I second the suggestion of our illustrious founder.@OP: Try something NONpermanent, first. (If it needs to be on your skin, try the Wizardry logo in henna.)
Try it for a VERY long time and see if you, and a string of future GFs (or the one, final, permanent GF) still like it.
Reason being: You are inclined to change, especially once you're out of your early 20s; a tattoo will not change with you.
Oh, the tattoo WILL change. Just not in any way you would like it to. Tattoos don't age well.
Wizardry's a GREAT game, one of the all-time greatest. CODS (Wiz7) revitalized my own interest, years after playing Proving Grounds (Wiz1). But let's place some reasonable limits on our devotion.
Or at least, give yourself a SUBSTANTIAL cooling-off period before doing something that cannot be changed (at least, not without a lot of additional pain and money).
If you still feel this way three years from now, go ahead. You're a responsible adult and may do what you wish with your body.
But don't be hasty.
