someone mentioned that tattoo foci could not be weapon foci. however, what if, for example, the tattoo amplified one's unarmed ability, i.e. dual flaming dragons from elbows to knucles? in that case would a DM consider allowing that? also, being that my current character is an unarmed pixie, would i not have enough space body wise for this? or could i just make it a full body tattoo spreading to my wings like dragon wings??
also, what are the perks and cons of weapon foci? do they just give more dice and make you look sketchy-er?
