A "Vector" IRL is an insect or mammal that can transmit diseases :3 What does it mean in TB tho'?

No I heard it mostly on the art threads like "Oh so you want a vector? That'll be expensive" or "[R]Half-Body Vector".

That depends...What is "this"?

Does it just mean to have it HD under 5x magnification? Is it like HQ heads or better?

But how is that possible?

Surprisingly yes it does make sense thank you for your help

Lol I haven't :3
