[Phantasm]

Third edition had half-point levels for skills, but that's about it. That was also one step below the skill level for a single point in the skill.

The nomenclature I used for it was "[0.5]": Skill Name (Specialization) (M/E*) [0.5] - skill_level.

That's about the only time we used fractional points, as even after modifiers became a thing for advantages and disads in 3e we rounded the costs.


*Using Mental/Easy as an example. We had Mental/Easy, Mental/Average, Mental/Hard, Mental/Very Hard, Physical/Easy, Physical/Average, and Physical/Hard, and IIRC there was different pricing between Mental and Physical, and also between Very Hard and everything else. All of them had ratings for half point values, even for spells. The only character I ever put a half-point in a skill had it in Driving (Automobile).
