Activates: May be cast up to 3 times if you have more than 3 Creatures of the specific faction in play after Round 4.
Talent Effect: Increases your Creatures' HP and Max HP by 50-150 (40 + 10 x Rank). (Formula seems off since heroes does not have 11 levels, 50+90 = 140).
This only applies to the creatures of the same faction as the hero is, i.e. Mortii Shield gives Mortii creatures HP, Faen Shield gives Faen's HP, etc.
