The mighty charger is a boon to heavily armored and armed champions, bearing them and their ironmongery into battle without hesitation.
Chargers treat Intimidate as a class skill.
When ridden by a cavalier, chargers gain half of the bonuses and penalties granted by the cavalier’s challenge class feature.
This ability replaces share spells*. The cavalier’s mount only gains half the listed number of bonus tricks (minimum 0).
At 3rd level, a charger’s armor check penalty for wearing barding or for carrying a medium load is reduced by 1 and the maximum Dexterity bonus for its armor and load increases by 1. Reduce the armor check and medium load penalties by an additional 1 for every 6 levels after 3rd; increase the maximum Dexterity bonus for the charger’s armor by an additional 1 for every 6 levels after 3rd. In addition, the charger’s speed does not decrease when wearing medium armor or carrying a medium load.
At 9th level, a charger can move at normal speed in heavy armor or while carrying a heavy load.
At 6th level, a charger becomes immune to fatigue.
This ability replaces devotion.
At 15th level, the charger gains the ability to withstand great punishment and stress. Whenever the charger succeeds at a Fortitude or Will save that would normally result in a reduced or partial effect, the charger is unaffected.
This ability replaces improved evasion.
Wait a minute… Cavalier mounts don’t get the share spells companion ability! Does this mean my cavaliers mount can not gain this archetype?
This appears to have been “stealth-fixed” in a PFS errata.
