This meme uses the "Anime Girl Hiding From Terminator" template, in mexico filter, where the text 'I, who can't even write 100 spells for my TTRPG' is layered over the anime girl, and 'Rolemaster casually having 2000 spells in 162 spell lists and 15 magic classes' in the Terminator, which is referring to the quantity of spells in the Rolemaster RPG's Spell Law book, one of the fundamental books alongside Character Law & Campaign Law, and Arms Law & Claw Law. And yes, before you say it, I know they're called professions, not classes.
your entire profile is nitpicking people's grammar
I just looked over the last ~50 or so comments of mine and I see, at best, one other comment that might be construed as nitpicking someone’s grammar (it’s not, but seeing as how you’re really fuckin’ dumb, I’ll give you the benefit of the doubt). I don’t know how your tiny little pea brain decided that meant my account was dedicated to that, but then again I do have to remember the bit about you being very fucking dumb and apparently proud of that fact, so here we are.
