the wanderer has traveled through the darkest places of the world and over time has gathered powers some would say is to evil and dangerous for humans.
Demonic Presence
-Aoe aura around the wanderer causes any spells/skills used by the enemy to deal damage back depending on the mana cost and causes a similar effect for allies except that it heals them instead of damaging them. Aura has 1000 Aoe. (Passive)
Level 1 - Deals/Heals .6 times damage per mana point consumed.
Level 2 - Deals/Heals .8 times damage per mana point consumed.
Level 3 - Deals/Heals 1 times damage per mana point consumed.
Level 4 - Deals/Heals 1.2 times damage per mana point consumed.
Mana Cost: N/A
Cooldown: N/A
Example: thunderbringer is being chased and casts his ult while near you that is 450 mana, this will heal thunderbringer for 540 damage. pyromancer casts nuke that does 950 damage on you which costs 640 mana, that deals 768 damage to the pyromancer. you can soul grip which costs 120 mana
Soul Grip
-Taps into an enemy's/ally's soul and shares the lifeforce in different ways depending which is targeted. If used on an enemy, a % of damage dealt to the wanderer will be sent to the enemy. If used on an ally, a % of the damage an ally takes will be sent to the wanderer. When used on an enemy, the % of damage sent is amplified by 25%. When used on an ally, the % of damage received is reduced by 25%. Lasts 10 seconds.
Level 1 - Sends/Receives 20% of damage
Level 2 - Sends/Receives 30% of damage
Level 3 - Sends/Receives 40% of damage
Level 4 - Sends/Receives 50% of damage
Mana Cost: 60/80/100/120
Cooldown: 20 seconds
Example: The wanderer uses skill and enemy, another enemy uses 300 damage nuke on wanderer, at level 4 the wanderer only recieves 150 of the damage and the enemy linked recieves 187 damage because it is amplified by 25%. the wanderer helps an ally being ganked, uses link, the ally gets a 1250 damage nuke from pyromancer, ally receives 625 damage and the wanderer receives 468 damage because it is reduced 25% before being applied. Damage is applied to the enemy(sent)/wanderer(received) even if no damage is dealt to the original target(wanderer or ally) because of backtrack or maybe a shield they had on since damage is split from the start.
Spirit Calling
-Focus on an area anywhere on the map that calls forth unholy spirits to strike from the ground after 1.5 seconds, slowing any enemies in the 400 aoe by 30% for 4 seconds and dealing damage.
Example: the wanderer is in bottom lane, at top lane an enemy hero is escaping with low health being chased but looks like he will outrun the ally, you cast the spell a little ahead so that after 1.5 seconds it lands on him, which kills the enemy off or slows it enough for the ally to catch up.
Metamorphosis
-Reading from ancient diabolic text, the wanderer can take form of a demon. as a demon, the wanderer gains unholy strength. the wanderer also loses its ranged attack and instead goes into melee for the duration. While in demon form, the wanderer can still use his spells. also, the wanderer heals himself for 2% of his max health each time he kills a creep,including neutral creeps, and gets healed for 10% of his max health for each hero killed by absorbing their souls. Lasts 20 seconds.
Seems a bit overpowered, especially the first skill which is ridiculously strong. These are some decent skill ideas, but they don't come together so well on this hero for the sake of synergy; you had a good thing going with the first two, which defined him as a sortof dangerous support hero, but the third seems a little tacked on and the ult is just a combination of doom and necrolyte's ultimate.
