ToME: the Tales of Maj'Eyal

In my character view for Valeria the ogre, my Size is listed as Gargantuan. However, I'm actually Size +4 (Ogre+belt+boots+ICCTW), and my Hit Penalty debuff for ogrewielding reflects that (-5% to each power).

The Size should be Colossal, if you're using D&D rankings.

"Gargantuan" is the last named size category. The size is tracked beyond it but the name doesn't change.
