Heavy Armor (重装甲, Jūsōkō) is a modified version of the white effect Armor. Spirits/Braves/Ultimates with this effect have the following text:
- Heavy Armor: Color(/Color) - This Spirit/Ultimate is unaffected by effects of opposing Color(/Color) Spirits/Braves/Nexuses/Magics.
There are two known variants of it. First, Infinite Heavy Armor, possessed by The GlacialHero Lord-Dragon-Glazar, Ultimate-Glazar and the revival version of The ArmoredSacred Walhalance, which gives Heavy Armor to effects of any color of symbols on your opponent's field. Second, Variable Heavy Armor, possessed by The MoonlightDragonDeity Lunatech-Strikewurm, The SixthArtifactKing Blion, and The EvilStarMachineDeity Loki which gives Heavy Armor to effects of any color the spirit itself has. For example, when braved with a Purple brave, it would be equivalent to having Heavy Armor: Purple.
