I would love to learn more about the archetypes and animal companions, if possible!
You can find a good amount of info about the archetypes on Reddit if you don't mind that format.
For the animal companions, there are six, I believe. Two in three different regions.Druma has the Bacallia (an alpaca-like animal that has glittering fur, a mount that can ignore either extreme heat or cold, dazzles with its support benefit, and has a 1 action Spit advanced maneuver that deals acid damage) and the Keulia (a horned lizard that wears gems, coins, and metal as "shell", has a support benefit like the bear but bludgeoning damage, and has a two action advanced maneuver to Leap and Bite with extra piercing damage). Both are non-finesse companions but the Bacallia's Spit would be dex based, I believe.
The Five King Mountains has the Cragstone Bear (a cave bear that grows plates of rock over its fur with imprecise tremorsense, a support benefit that gives a circumstance bonus to AC to you while adjacent, and a two action advanced maneuver to roll in a straight line and make one Strike that knocks prone on a crit) and the Giant Rock Tuatara (a bigger version of the familiar Shardra has with a support benefit that inflicts clumsy, and a 1 action advanced maneuver that sheds its tail to escape from a grab or retrain as if it had critically succeeded, but then can't use its tail for ten minutes or until it receives magical healing). Both are strength based. (There's also a grindle-drake specific familiar)
Galt has two undead companions, the Gray Bladeling (a construct that can be void healed, with weaker than usual animal companion stats but many immunities from being both undead and a construct, a support benefit that bleeds or frightens if already bleeding, and a two action advanced maneuver to Strike a living creature and stun/confuse it on a Will save) and the Severed Head...
Rad thanks!
