Arryn stonewall and fire armor

Is arryn stonewall the only hero who can cast fire armor.

Oh, Warcry is a skill that Arryn Stonewall and Hattori Hanzō can use, although they have different effects depending on the hero you use.

No, I’m talking about fire armor, where there is a red helmet glowing over the caster. Do know what I mean?

Do you mean Warcry or Flame Armor?

That is Warcry, Trevor. The red helmet is the symbol of a unit affected by Warcry. In Arryn’s case, it increases the attack mass of those affected by two.
