Endurance

From Colawikki

Endurance determines by how much CCS Stamina increases with each level.

When a player levels their maximum stamina is increased by a base 15 plus an extra increment based on endurance; this is currently set at endurance/2.5.

Players should note that during a respec, CCS no longer allows a player to determine stats at each level but instead asks for desired final stat values. Because endurance is applied at each level, total stamina depends not only on total endurance but also on how it was added at each level. The respec page calculates stamina by applying a simple formula to decide how many endurance should be allocated at each level.
