Gish - a fighter/wizard multiclass character
Also, I feel I should point out that I freakin' hate hate HATE this word, for some reason. It sounds stupid as hell, and now I'm even pissed off at myself just for typing it. It originally was specifically a githyanki fighter/m-u combo. Unless you're playing a githyanki, you aren't a gish. It's a dorky word, and you automatically become a big stupid dork if you refer to your character thusly. What, it's too much of a strain to say "fighter/wizard?" Is saying all those syllables taking away from valuable Cheeto-eating time? Do you sound cool and fantasy-worldly to casually drop such a retarded-sounding word? Gaaah!
Seriously, I don't know why it bugs me so much. Anyone I see using it will be put on My List (tm)*. And that does include whatever jokester is about to fancy himself to be a comedian and use it several times in a post just to be "funny". YOU'RE going to the top of My List (tm), pal!
* - Inclusion on My List (tm) subjects the listee to (but not limited by) the following: kidney punches, the hairy eyeball, barely audible snickers and snide commentary, being unfairly subjected to wandering monsters in any game I may run, being unfairly subjected to PC-on-PC violence in any game I may play alongside you, vulgar comments about your sister and/or other female family members, and a handful of d4's jammed where you don't want 'em.
EDIT: Great minds think alike, Henry! You posted that while I was busy typing and stewing in my rage.
