("Big Boy Pants")
That is the translation of the phrase, at least. These purple undergarments were found in the chamber of the Forge of Spells, having been enchanted in the distant past.
The wearer's Strength is increased by 1 (max 20), and he or she is considered one size larger (i.e. Large instead of Medium) when advantageous. For example:
- Grappling or avoiding being grappled or restrained.
- Carrying capacity.
- Resisting poison when based on size of the creature.
- Using two-handed weapons as single-handed.
- Using single-handed weapons as light weapons.
