Keleseth by MrBr0s

Level 1

Insatiable Thirst

Increase the bonus damage of Dark Transfer by 50% and the range of Essence Leech and Runic Trap by 20%. Activating Dark Transfer grants 30% Movement Speed for 4 seconds.

Dark Pact

Enemies hit by Essence Leech leave behind a black orb that lasts 3 seconds. Walking over a black orb sacrifices 6% of Keleseth's maximum Health to reduce the cooldown of Essence Leech to 1 second, destroying any other active black orbs.

This is a Blood Magic talent.

Notes:
- Health is sacrificed even when Protected, Invulnerable or Untargetable
- Health is sacrificed through Shields
- Black orbs are ignored when Health is insufficient

Blood for Blood

Enemies that damage Keleseth during Blood Nova take 30% of the damage inflicted over 3 seconds as Blood Nova's damage type. Additionally, the duration of Regeneration Globes does not decay while Blood Nova is active.

Level 4

Roiling Blood

Blood Nova grants 35 Physical Armor and Slows nearby enemies by 25%, but its healing is reduced to 60% of the damage done.

Crimson Storm

!Quest: Every time Blood Nova sacrifices a total of 15% of Keleseth's maximum Health, Runic Trap rotates a quarter of a turn around him.

!Reward: After Runic Trap rotates 20 times, reduce the amount of Health required to 10% of Keleseth's maximum Health.

This is a Blood Magic talent.

Notes:
- Quest progress is saved between Blood Nova casts

Unholy Runes

Increase the duration of Runic Trap by 3 seconds and reduce its Mana cost by 15. Additionally, the cooldown of Runic Trap recharges 200% faster while a Hero is Rooted by it.

Notes:
- Increases the duration of the runes, not the Root effect

Level 7

Vampiric Frenzy

Dealing Physical damage to Heroes marked by Dark Transfer deals 50% of its bonus damage to enemies around the target. Healing from secondary targets is reduced to 50% of the bonus damage done.

Notes:
- The damage scales with any modifiers that affect the damage of Dark Transfer

Life Funnel

Upon return, Essence Leech deals up to 60% more damage to enemies the further they are from Keleseth. This bonus is doubled against Rooted or Stunned Heroes.

Unending Resolve

Increase Keleseth's maximum Health by 10%. Increase Spell Power by 1% for every 8% of missing Health, doubled while under 50% Health.

This is a Blood Magic talent.

Level 13

Hunger Strike

Active
Cooldown: 30 seconds

For the next 4 seconds, Keleseth's healing effects sacrifice his Health instead. When the effect ends, Keleseth is healed for an amount equal to 175% of the sacrificed Health.

This is a Blood Magic talent.

Notes:
- Health is sacrificed even when Protected, Invulnerable or Untargetable

Consuming Shadows

Hitting enemy Heroes with the initial area of Essence Leech reduces their Spell Power by 20% and Physical Armor by 15 for 2.5 seconds. Hitting enemy Heroes upon return pulls them slightly and grants 20 Spell Armor for 2.5 seconds.

Knockback duration: 0.15 seconds
Knockback speed: 14

Notes:
- The Physical Armor reduction is applied before the damage is dealt

Runes of Frost

Increase the Root duration of Runic Trap by 0.25 seconds. Rune eruptions apply Dark Transfer to enemy Heroes hit and Root them if they were already marked.

Notes:
- The Root from eruptions follows the same rules as the base Root from Runic Trap

Level 16

Fury of the San'layn

Hitting a Hero marked by Dark Trasfer with Essence Leech increases Attack Speed by 8% for 6 seconds. Gaining at least 32% Attack Speed from a single cast grants 50% Attack Speed instead.

Passive: Increase all Physical damage by 10%.

Notes:
- The Attack Speed bonus is capped at 50%
- The Attack Speed bonus can stack up to 16% per enemy Hero if Essence Leech hits them twice
- The Attack Speed bonus from each Hero hit is unique and is overwritten when refreshed

Edge of Madness

Increase the Health sacrificed by Blood Nova by 1% per second for every nearby enemy Hero.

This is a Blood Magic talent.

Notes:
- The sacrifice bonus is re-calculated on every tick

Unstable Runes

Runic Trap can Root the same enemy Hero a 2nd time, but it removes Dark Transfer from them when doing so. Additionally, increase the radius of runes and eruptions by 30%.

Level 20

Coagulating Orb

Increase the damage of Orb of Corruption by 2% and its Armor by 1 for every 2% of its missing Health. Reduce the cooldown of Blood Ritual by an additional 4 seconds and cause it to also affect the return damage of Essence Leech.

Change of Fate

If the target of Twisted Fate survives the curse, increase Keleseth's damage against them by 25% for 10 seconds. If Keleseth dies during Twisted fate, his respawn timer and the cooldown of Twisted Fate are reduced by 50%.

Blood Magic

Reduce the cooldown of Dark Transfer by 4 seconds and its Health cost by 20% for every chosen Blood Magic talent. Additionally, gain the first unchosen Blood Magic talent.

Notes:
- The gained talent counts towards the effect.

Manavore

Active
Cooldown: 1 second

Activate to consume 50% of Keleseth's current Mana to heal for an amount equal to 400% of the Mana consumed.

Passive: Increase Mana Regeneration by 75%.

Crimson Storm (lvl 4):
Quest requirement reduced from 30 to 20.

1.2 (04/19/2022)

GENERAL

All Health-sacrificing effects are now unusable while Health is insufficient.
Keleseth is very bold, but not that much ;)

ABILITIES

Dark Transfer (D):
Cast time increased from 0.125 to 0.25 seconds.
Damage reduced from 40 to 20.
Health cost increased from 8% to 10% of current Health.
Adjusted functionality: The bonus damage is dealt to any non-Structure target instead of only Heroes, and is doubled against Heroes.
My initial design of Keleseth intentionally gave him no self-healing from non-Heroes to give more weight to his Health sacrifices, especially in lanes. However, I felt like this might make his Health-costing effects too hard to use when trading with enemy Heroes, so I gave him a minor source of self-sustain against non-Heroes as well.

Essence Leech (Q):
Healing increased from 30% to 35% of damage done to Heroes

Runic Trap (E):
Rune radius reduced from 2.0 to 1.75.
Rune distance increased from 2.75 to 3.25.
Eruption radius reduced from 3.0 to 2.5.
The dimensions of Runic Trap have been adjusted so that it is safer to use, but requires more precision.

TALENTS

Dark Pact (lvl 1):
Health sacrifice increased from 5% to 6%
Adjusted functionality: Spawns black orbs on enemies hit instead of only at target location.
The previous version would have been quite awkward to use, requiring both risky positionning AND a Health sacrifice. These changes allow orbs to potentially spawn a lot closer to Keleseth, making the Health sacrifice the only drawback.

Blood for Blood (lvl 1):
Reflected damage reduced from 40% to 30%.
Damage duration reduced from 4 to 3 seconds.
Additional functionality: The duration of Regeneration Globes does not decay while Blood Nova is active.

Roiling Blood (lvl 4):
Moved from Level 7.

Crimson Storm (lvl 4):
Moved from Level 7.

Unholy Runes (lvl 4):
Moved from Level 7.
Initial requirement per rotation increased from 10% to 15%.
Requirement after quest completion increased from 5% to 10%.

Vampiric Frenzy (lvl 7):
Moved from Level 4.
Now only triggers when dealing Physical damage.

Life Funnel (lvl 7):
Moved from Level 4.

Unending Resolve (lvl 7):
Moved from Level 4.

Fury of the San'layn (lvl 16):
Duration increased from 4 to 6 seconds.

Coagulating Orb (lvl 20):
Swapped places with Change of Fate.
The orb can no longer become Protected.
Additional functionality: Grants the orb 1 Armor for every 2% of its missing Health. Reduce the cooldown of Blood Ritual by an additional 4 seconds and cause it to also affect the return damage of Essence Leech.

Change of Fate (lvl 20):
Swapped places with Coagulating Orb.

Slow amount reduced from 20% to 25%.

1.1 (12/11/2021)
