Armor

Encumbrance
All armor has strength requirements to equip it. For each piece of armor an adventurer has equipped, it's strength requirement is divided by their total strength. The result is multiplied by 25% and added to the Encumbrance rating for the player. For example, a player with 20 Strength who equips only a single 10 strength requirement piece of leather would add a total of 0.125 to their encumbrance rating.

For each step or swing taken by the player, their current encumbrance total results in a chance to lose stamina. This chance is equal to the encumbrance value. a .125 encumbrance would have a 12.5% chance to lose a point of stamina per step. Or roughly speaking once every 8 steps. Any total greater than 1.0 guarantees at least 1 stamina lost, in addition to any remainder proceeding to the above stated calculation.

The result of this system is that strength continues to be significant well past the point that you qualify for the minimum stat requirement of the armor. Additionally, the Fighter ability "Armor Proficiency" halves the contribution to encumbrance from 25% to 12.5%.
