Rolemaster
A traditional fantasy-genre game¸ originally designed as a modular addition to other games (""Arms Law""¸ ""Spell Law""¸ ""Character Law""¸ ""Claw Law""¸ and ""Campaign Law""). The system uses skill plus an open-ended percentile roll resolved on a table¸ with tables for each weapon and skill. Character creation was originally random-roll attributes and limited point-buy skills¸ modified by choice of class. A given class had its own cost for each skill type (i.e. weapon skill costs 10 for a magician but 3 for a warrior). Later they added a separate attribute point-buy system. - A description from https://darkshire.net/jhkim/rpg/encyclopedia/ with kind permission of John H. Kim"
