At the least the +4 from Earth Bless stacking from multiple bracers is a bug. I'd consider getting +4 from the bracers on top of the standard +4 from wearing armor to be a bug, but that may be a minority view.
The real strength of this probably doesn't come in with massive protection on late game SCs but cheap low-fatigue high protection on early game recruitable thugs. Y
It seems to me that if you get more than one copy of the earth bless bonus, regardless of what you're wearing, it's a bug. It should be (and was almost certainly intended to be) 0-1 depending on what you're wearing.
Mmh, i think there must be a reason if they were made stackable, I'd wait for enlightenment At least theydon't seem me unbalanced or too hard to counter someway, do you (and why)?
