Intelligence Improved (5e Variant Rule)
From D&D Wiki
Intelligence is typically used as a “dump stat”. It simply determines a handful of skills, of which only 2 are semi-regularly used, and the spellcasting of a single class. Well no more! Intelligence now effects the following:
- You may be attuned to a number of magical items equal to your Intelligence modifier (minimum 0).
- When you earn experience, you earn an additional amount equal to your Intelligence modifier x 2 (minimum -8).
