Seeking to rectify this slight, I've created a complete concept for the Hero that hopefully keeps true to his original D2 nature. Hope you enjoy.
MEHTAN, PRIEST OF RATHMA
-----------------------------------------
Introduction
Mehtan, the Necromancer is a ranged specialist who excels at pressuring lanes by creating groups of skeletons that will follow their master until they are destroyed. His varied toolkit allows him to be built to fit a variety of situations.
Strengths
- High sustained damage
- Joining a team fight with a full contingent of skeletons serves as a major contribution with no set-up time or mana cost
- Iron Maiden provides a unique form of crowd control
- Grim Armor offers great utility as it can help protect your hero from burst damage or be used to add to your own burst damage
- Can easily capture Mercenary camps once Skeleton army is built
- Skeleton summons can be used to soak Fort/Tower ammo and provide protection from skill shots such as, but not limited to, Gravity Lapse
- Reanimate Heroic can instantly turn the tide of close Team Fight
Weaknesses
- Lacks any form of "hard" crowd control
- Very mana dependent
- Low max health; vulnerable to crowd control
- Skeletons can't be created in a team fight situation unless you contribute to a Takedown or kill a lane minion
- Relies on building momentum through creation of skeletons to reach full effectiveness
- Lacks mobility aside Bolt of the Storm at Level 20
- Reanimate heroic has no value if there is no one to "revive" or if Mehtan is focus fired down first
COMBAT TRAIT
Bone Collector
Cooldown: 5 seconds
Description: Your attacks will curse enemies for 4 seconds. Enemies that die while cursed will summon a Skeleton Warrior to guard you until it is destroyed. You may only have 3 skeletons active at a time.
Skeleton Warriors have the following stats:
Health: 160 (+25/ level)
Attack Speed: 1 / second
Attack Damage: 10 (+2 / level)
ABILITIES
Bone Spear (Q) Mana: 65
Cooldown: 10 seconds
Desciption: Deals 110 (+ 25 / level) damage to enemies in a line.
Grim Armor (W) Mana: 60
Cooldown: 10 seconds
Description: Places a rotating bone shield with 230 (+30 / level) health around your hero for 6 seconds. When shield breaks or duration expires the shield explodes in a small area around the hero dealing 120 (+ 20 / level) damage.
Reactivating the ability will immediately remove the shield and deal damage.
Iron Maiden (E) Mana: 75
Cooldown: 12 seconds
Description: Places a curse upon enemies in small area that causes them to take 25% of the damage they deal in return for 2 seconds.
Ranged *abilities* are excluded from taking feedback damage; however, ranged auto-attacks will still result feedback damage.
Example 1:
Iron Maiden is cast upon a hero who deals 200 damage per auto-attack as he is clearing minion waves. Any auto-attacks he performs during the 2 second period will deal 50 damage to himself.
Example 2:
Iron Maiden is cast upon Kael'thas just as he casts Flamestrike on 4 heroes. He takes 0 damage in return (instead of the likely instantly killing him).
HEROICS
Summon Golem Mana: 75
Cooldown: 80 seconds
Description: Summons a Blood Golem to guard you for 20 seconds. Its attacks deal 100 (+ 10/lvl) damage and heal you for 50% of each attack's damage if you are nearby.
Reanimate Mana: 100
Cooldown: 100 seconds
Description: Partially revives your team's last fallen ally at the location they died for 15 seconds or until their death timer runs out.
During this time, that player gains control of a "revived" copy of their hero with the following changes:
* The revived hero has 75% of all stats as their normal hero.
* The revived hero's cooldowns have been reset so that any non-heroic ability may be immediately utilized upon revival.
* Non-heroic abilities used by the revived hero will not effect the cooldown status of the normal hero when they return.
* If the revived hero's heroic is not on cooldown it may be used but will reset their cooldown timer as normal so that it is unavailable when they return to normal gameplay.
HERO STATS
Health: 730 (+130 / lvl)
Health Regen: 1.65 (+0.35 / lvl)
