In low-level D&D variant E6, you max out at level 6 and only gain feats every 5,000XP thereafter. There is a feat as follows:
Skill Beyond Your Years
Prerequisite: Level 6
Pick a skill. Your max ranks rise from Level+3 to Level +5.
Is this feat of any actual use? You can't gain levels past 6 in E6, and therefore can't gain further skill points even if your max ranks goes up.
