Passive: Sacred Fire
Targets hit by Fire Crash receive a Mark of the Flame, which strengthens the next ability Ignis uses to attack those targets. The mark lasts for three seconds, and when it is eaten by an ability, Ignis is restored to full health for 100 HP (+5 each level) and resets the cooldown for Fire Crash.
Skill 1: Fire Crash
Ignis fires the Sacred Flame as an orb, causing 300/340/380/420/460/500 (+0.4 AP) magic damage to the first enemy it hits as well as those in its immediate vicinity in a cone behind it. Ignis’ movement speed is also increased by 40% for 1 second. If the designated targets are struck, Ignis obtains a shield for three seconds that deflects 300/400/500/600/700/800 (+0.65 AP) damage.
Skill 2: Rain of Fire
Ignis calls forth a Rain of Fire, which lasts for three seconds and deals foes nearby 135/170/205/240/275/310 (+0.45 AP) magic damage every second while also slowing them down by 30% for two seconds. Marked targets suffer a 0.75 second stun.
Skill 3: Holy Embers
Ignis summons a formation of Sacred Fire that, after one second, deals 700/900/1100 (+0.9 AP) magic damage to enemy heroes nearby. 800/1000/1200 (+1 AP) True Damage is dealt to marked targets.
