This is very different. Show your geekdom with a tat. The D20 and the last beholder are particularly nice. Would I do it? Absolutely not. :D
I have thought about doing something like a D&D style tat, but more along the lines of a mural/sleeve rather than just a single image. Though, I will say, I really like the d20 one.
I've been thinking about getting a Thought Eater tattoo... or maybe a Beholder or Intellect Devourer...?
