Human: different, covered above
Elf: the same evasion bonus
Beast: the same 10% bonus damage for (2), but (4) and (6) give a chance to summon Pets at the beginning of combat – Beasts are essentially a summoning build here.
Cyborg: the same as Goblins (Scrappy) in other Auto Battlers – armor and regen on a random ally.
Furry: the same as Brawny/Cave Clan (HP shield instead of HP, but essentially the same)
Goblins: to add confusion, here Trolls/Glacier were renamed to Goblins. The same attack speed bonus.
Undead: the same armor reduction
Demon: the same bonus damage, but 10% damage amplification debuff as well
Oceanborn: aka Naga in the other games, the (2) unit bonus gives the same magic resistance. The (4) unit synergy, however, gives a magic immunity shield to a random ally (essentially a BKB).
Void: a replacement of Elementals/Primordials. (2) Voids decrease a random enemy’s max health to 50%.
Dragon: (2) Dragons restore 30, (3) Dragons – 100 mana at the beginning of the round.
Jelly: a one-unit synergy, a replacement of IO.
