Tier 4 or 5 Tome: Tome of Giants

[clever tree]

Control Loss Immunity and Fearless for a entire race is never going to happen, and having the unit size shrink to one model is actually a benefit not a downside

I think considering the size of giants that might be a problem as well, giants have their own unique models after all, but not sure might be fine in terms of modularity since we do have ancient of the earth

[placid steeple]

I like giants. I’m cool with something like this.

[sick sage]

the Control Loss Immunity Treat or Fearless Treat, could also become an Enchantment in the "Tome of Giants" but yeah it would be too much

[sick sage]

for the INITIAL BONUS (+1 Nature Affinity +1 Materium Affinity) or (+2 Materium Affinity) and I had imagine the faction would be able to construct a building that will allow to recruit pure Giants, like the "Wyvern Eyrie" from the "Tome of Dragons", and the "Hero Ascended Skills" could be a Buff to Giant type units in combat

Control loss immunity should be scrapped entirely for this transformation. It doesn't make sense here at all, and a different major transformation uses it as its selling point. Fearless would be OP. Even the undead only get cold-blooded.
