      Not that powerful on it's own, when used in combat, but excellent for pre-buffing yourself prior to combat, since it lasts 5 turns.

        The tooltip does not reflect the complete effects of the skill. its basically fortify and mend metal in one (minus the extra effects of fortify) and thus justifies the AP cost. Belongs to the polymorph tree which is a great supplemental tree for any character. Probably one of the most underrated skills in the game.

          Playing as a Warfare + Necro + Poly character using two-handed weapons and wearing mostly Int. armour (using him as a dedicated mage killer), found this skill really useful for survivability against opponents dealing physical damage, especially early on. Probably worth using on any warrior/fighter character who isn't using shields.

            How is it that this skill scales with Geomancer but not with Polymorph? You know given it’s a Polymorph skill? No?

              Note that Heart of Steel scales with neither INT nor STR. It only scales with Geo.
              Pyro 10 Geo 10 Mage could use this skill to pump up physical armor.
              Warfare 10 Geo 10 Warrior could use this skill to combine with Bone Cage, Overpower, Reactive Armor etc.

              At level21(Geo5) mage can have 1k physical armor ~ 3k physical armor with a shield.
              Basic Physical Armor : 1,000 ~ 3,000
              Heart of Steel : 1807 + 598 × 4 turns = 4,199
              Fortify : 2408
              Tooltip doesn't tell you this, but Heart of Steel increases physical armor by 1807, making total increase 4,199. If you have Geo10 character, it'll be a bit more powerful. Both Fortify and Heart of Steel can be a good tool skill.

              Not that it is important to be level21. It's just I was at level 21 when I tested this. It'll be the same at any level.

                This is the most useless skill in the game. 2 AP, 5 CD and mediocre amount of physical armor.
                On the other hand you could to Fortify which is instant armor plus unable to be teleport/nether swapped, plus removes some conditions. 1 AP, 4 CD.
                And if you wanted to, for 1 AP, you could do Mend as well and that is also an AoE for allies.
                Heart of Steel is a useless skill.
