Arcane Shield

Mage skill · Arcane line · tier 2

Beta 0.7.2

Four shields of purple runes spin around each hero.

It is only used in combat once it is placed on the hero's active bar, and its 12 s cooldown is before cooldown reduction.

Values by rank

Arcane Shield scales with Absorption. Its value at each rank is 1.2 + 0.8 × rank:

Rank	1	2	3	4	5	6	7	8	9	10
Value	2	2.8	3.6	4.4	5.2	6	6.8	7.6	8.4	9.2

The value is the game's internal number for this skill.

in combat = round(value × skill power × 5 × max(0.35, hero damage ÷ 600))
hero damage = Attack + all elemental damage
skill power = 1 + 1% per point in the other Arcane skills + 2% per rank of each skill that boosts it

The damage factor has a minimum of 0.35 and no maximum. A hero with 600 damage and no line mastery or synergies gets the listed value × 5; how it becomes damage or healing per hit depends on the skill's type and timing.
