The heavy armor of a Beastmaster shares the same base characteristics as Zealot's armor, although it is thicker, well-shielded and provides full enviro protection (fire & gas) - Beastmasters are much more valuable and usually leave attacking to their pets, so mobility is not required. The defining (and expensive) feature of this armor is its ablativeness - if the damage is too great to withstand, it explodes outwards, revealing a pretty much unharmed and very pissed Beastmaster.
