Some companions live lives of faithful devotion and steady vigilance, standing watch through long hours and always ready to leap into action to protect their master.
A bodyguard and its master both gain Alertness as a bonus feat whenever they are adjacent.
This ability replaces share spells*.
At 3rd level, a bodyguard can always act in a surprise round (though it remains flat-footed until it acts). As long as its master is adjacent, a bodyguard remains conscious (though it becomes staggered) when its hit points fall below 0. While below 0 hit points, the bodyguard loses 1 hit point per round but gains a +2 morale bonus on attack rolls, saving throws, and skill checks, dying only if its hit points reach a negative total equal to its Constitution score plus its master’s class level.
This ability replaces evasion.
This ability replaces Multiattack.
At 15th level, a bodyguard with fewer than 0 hit points gains a +4 morale bonus on attack rolls, saving throws, and skill checks; immunity to fear effects; and temporary hit points equal to its master’s class level (maximum 20). It dies only if its hit points reach a negative total equal to twice its Constitution score + its master’s class level.
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?
Companion archetypes (especially the Charger archetype) were intended to be available to cavalier’s mounts.
A cavalier’s mount should therefore be treated as having the share spells feature for the purpose of qualifying for animal archetypes.
