This is for people who do not like the 5th edition rules for magic items that alter your ability scores. If you feel like items that set your strength to a specific level penalizes characters who choose to invest in their strength via ability score increases, this is an alternative for you.

While you are wearing and attuned to this magical belt, your Strength Score increases by 4, as well as your Strength Maximum. You may only benefit from one such enchantment at any given time.

Notes: Bonus: Strength Score, Bonus: Ability Score Maximum, wearing it for an hour
