Not sure if this has been noted before, I did a search for "Cyclone Armor" and found nothing relevant. In any event, my apologies if this has been addressed somewhere.
Frostbite does not increase the amount of damage absorbed by Cyclone Armor. Twister, Tornado and Hurricane all synergize correctly, but no matter how many points go into Frostbite, the damage absorbed remains the same. It works correctly the other direction (Cyclone Armor boosts Frost Bite's damage).
I'm using 1.21z, Single Player edition. Found the bug on my Frostbiter (see Strategy & Tactics) and then confirmed it with two separate test characters. Anyone else care to test this, or let me know if this has already been reported?
Thanks
