Stamina

Stamina measures the ability to sustain physical effort. Stamina is required for attacking, blocking, kicking, jumping, sprinting, and swimming and is represented by the yellow bar.

Each point in strength provides .6 stamina.
Each point in constitution provides 1.2 stamina.

"Stamina management" is the art of not running out of stamina too quickly in a fight, and is regarded as one of the top skills players must learn.

The Stamina Drain Modifier is the rate what which stamina is depleted. Each piece of equipped armor has a Stamina Drain modifier that impacts overall stamina drain. Heavy armor drains stamina much faster than light or medium armor.
