Capped Skill Bonus (3.5e Variant Rule)

Capped skill Bonus
Skills were alway a problematic part of D&D, from Incantatrix spellcraft abuse to the diplomancer, abusing skills can effectively created massive power creep and bring many balance issue, such as completely breaking skills like bluff and diplomacy.

This variant cap skill bonus at HD + 13. A 1st level character skill cap would be +14 (ranks, ability bonus and items included). Racial bonus ignore this rule.

If you exceed your maximum skill bonus, instead of increasing the result of your roll you gain the ability to reroll a particular skill once (immediate action) once per day per skill bonus above your capped bonus. By example, a 13th level character with a +28 bonus (max +26) would only add +26 to his skill check, but gain the ability to reroll a skill check (involving this particular skill) twice per day (you can never reroll the same check twice).
