Character Concept: Blood Knight
Blood is the lifeforce of practically every living thing. Not plants, but who cares about that. Blood merely allows most to continue on with their empty lives, but for a select few, it can be empowering when partaken. Come with me as we consume the blood of others for our own personal gain and make all regret not building a single anti-healing item. Bring forth a melee physical fighter that harvests the juicy body liquid that is blood. Numbers can always change.
Passive- Attacks spawn blood worms every so often that fight with you for 10 aa's. Upon the 10th, they burst and heal you. If they are killed, the enemy gains a percent of the healing based on the hits the worm did up to 50%. Worms are immune to aoe damage. Ex. 4 hits for 40%. 1 for 10%.
Ability 1- Deal aoe damage and become empowered with your worms based on the missing hp of enemies to deal bonus damage on your next aa.
Ability 2- Bloody swords go forth (2) and leave behind a blood trail. The swords impale the first enemy hit, impaling them to deal damage and cause them to leave behind a blood trail for 5s. On the blood trail, you gain movespeed. If both swords hit 1 target then you become Blood Surged and gain double movespeed.
Ability 3- Swing your sword in a complete circle to damage enemies and cause Blood Letting on them which deal DoT that deals more damage to healthier enemies. For each enemy hit, your bloodworms gain X% attack speed.
Ult- Passive- Gain 10/20/30% life steal and spell vamp. Active- In a cone, draw out enemy destroyer blood, causing them to take 10% of their max hp over 5s. You gain the hp that you sap as bonus hp for 10s. If you have less hp than what you stole after 10s, you will die.
The Blood Knight, with his bloodworms at his side, can out sustain the best of them when he can actually get onto a target. He has no cc as a result and his only form of mobility is landing his W. He can be kited and you need to build anti-heal or bring an anti-heal destroyer (maybe I'll show that one off one day). There's not much to say here as it should be plain as day how you play as and against them.
Anyway. If you like it, cool. If you don't, hey. At least it ain't in the game.
