Skeleton King

Skeleton King

Skeleton King was a very useful hero back then. He still is now, but not as much due to other better support heroes. Known for his Flaming Deer, he now receives a booming legendary skill to add along with them.

Skills: 

His special, "Royal Summons", in which he is most known for, heals himself and summons a Skeledeer with a certain amount of health (And a lot of health, comparable to Dark Horse's) into battle. This keeps King alive and summons a viable tank, good for pairing up with Pixie Queen as when he summons the deer, Pixie can just special and become a backline instead of having to tank. The deer does magic bashing damage. His green skill, "Hail to the King", either heals an ally or damages a foe. It targets the ally or foe with the lowest health, healing the ally for a certain amount or damaging a foe for double. It does magic necrotic damage. This skill is somewhat unreliable for healing and damaging, as if an ally needs healing, King cannot target only them and will always hit the target with the lowest health. It's a downside as there are situations where an ally who's about to die doesn't get healed and dies anyway because King targeted the foe who would've died to his basic attack. However, it still is a good healing support skill. His blue skill, "Bewilderbeast", makes his Skeledeer charge into the farthest foe when summoned, and when stopping, the deer does physical damage and stuns the enemy it hits for two seconds. Every seven seconds the deer does the stunning attack again. This stunning attack does not rely on skill level, for it will almost always stun. It's perfect for stunning backline Genies, Spikies, Wolves, and other Kings. His purple skill, "Hot to Trot", creates a fire ring around his summoned deer. The fire ring does magic fire damage to all foes around the deer. This is good for some extra damage and for an emergency Cloud/Stone Imp killer. 

Rune Sets: 

Bolt Hail is recommended, but you know about Hail. Bolt could be good for his green skill, (It doesn't affect cooldown reduction, only animation speed, but still), but I'm not sure whether it affects his deer too or not. River could be good for him, so he could get out his deer faster and to replace it faster. As for his two setter runes, either Hail, Mist, Rock, or Tree. Blood's a no no, as it'll only affect his basic. Perhaps Ocean could help with the fire ring and his green. Ocean's also a preferred set for Skeleton King, affecting the Deer's health, the amount of healing and damage done by his green, amount of damage his deer's stunning skill does, amount of damage his deer's fire ring does, and the amount of damage his legendary does.

Rune Bonuses:

Improve Healing, Armor and Magic Resistance Growth, Magic Penetration, Fire Damage, Necrotic Damage, Skill Power, Fury, Conservation, Cooldown Reduction, Attack Speed, Longer Disables.

Unnecessary, but do have a positive effect bonuses: 

Tenacity, Dodge, Max Health Growth, Basic Damage Growth, Armor Penetration, Life Steal, Bashing Damage, Crit Rating and Damage, Starting Energy, Expertise, Movement Speed, Accuracy.

Ending Note:

Skeleton King's legendary'll mess up a lot of things soon. especially temples, and ruining Spectral Drake's anti deer.

Edit: Skeleton King's legendary deals about 10,000 at the early levels. Skeleton King's legendary now makes it so that you can kill the active deer (making the legendary trigger for the hefty magic damage) and spawning a new one by reactivating the special. This makes a River set viable. His legendary is reliant on skill power.
Extra Edit: His special's self healing is now reliant on skill level and cannot be affected by improve healing. It's a small amount.
