I find it strange that the crest of almire is strong vs fire, and the armor is weak vs fire.
So is almire strong or weak vs fire? This is very inconsistent, and in fact, the opposite of a motif.
It would be like putting sword damage reduced on snarby armor :/
A possible explanation is that the Crest of Almire was designed to resist fire 'because' the armor is weak as to counteract the armor's weakness.
