1 stamina gives 0.45 stamina untalented (erroneously reported as 0.3 stamina in the Hunter's stamina tooltip), or 0.63 stamina with 2/2 Wild Hunt. Hunter pets do not gain any health from their base stamina, and gain 10.5 health for each additional point of stamina (10 health per additional stamina before the inherent pet health bonus, which was standardized to 5% in Patch 3.1.0).
