If Sylas kills an enemy champion with his W the healing is increased to 1.5-2 times the intended amount.
This is especially troublesome in combination with the bug described earlier on here - [[GAMEPLAY] Sylas - Able to cast empowered W without mana if under the threshold](https://boards.na.leagueoflegends.com/en/c/bug-report/3NfGyAqh-gameplay-sylas-able-to-cast-empowered-w-without-mana-if-under-threshold)
1. Get Sylas under 40% health
2. The indicator for W will show animation for the empowered cast
3. Kill the enemy champion with your empowered W [Damage and Heal empowered in the example]
4. The healing is increased to 1.5-2 times the intended amount [with multipliers of Revitalize and Conqueror bonus in the example]
The bug only happens if your killing blow is with Sylas W.
The calculation down below is for the example video:
Provided in this Reddit post - [New Conqueror and Sylas W gives the dumbest heals](https://old.reddit.com/r/leagueoflegends/comments/ataqqs/new_conqueror_and_sylas_w_gives_the_dumbest_heals/)
Important notice: This video has Conqueror before the hotfix.
Values are: 1.8-9 AD / 3-15 AP based on level, in this case, 5.82 AP per stack for level 5
Sylas level 5 with 18 AP [+29.1 AP bonus Conqueror 5 stacks] Rank 3 W | UNDER 40% HP
Level 5 Sylas
Abilities: Rank 3 W, Rank 1 Q and E
Runes [Irrelevant for the bug] in this case are: Conqueror, Triumph, Legend: Tenacity, Last stand and Shield bash, Revitalize.
Rune bonuses: 18 AP + 5 Armor
Items: Sheen + Corrupting potion
Sejuani level 4 with no bonus magical resistance -> 34.9 MR
This means Sejuani will have 100/134.9 = 0.741289443291327% damage multiplier or plainly said ~26% magic damage reduction
Empowered heal value:
220 [Base value of heal for the rank 3 W when under 40% HP threshold]
+ 34.1 [15.5% -> ((100% + 5%) *10%) - Revitalize bonus for the value of 220 when under 40% HP threshold defined by Revitalize rune]
+ 32.97 [0.7% bonus AP scaling for the rank 3 W. Total AP: 47.1 (Conqueror 29.1 + 18 on rune bonuses)]
+ 5.11035 [15.5% Revitalize bonus for the value of 32.97]
Base damage value:
180 [Base value of damage for the rank 3 W when the enemy is under 40% HP threshold]
+ 38.8575 [0.825% bonus AP scaling for the rank 3 W when enemy is under 40% HP. Total AP: 47.1]
This above is damage before magic resistance.
Conqueror will take this for the base damage/heal calculation giving a value of: 21.88575 damage/heal
Now we have two different damage calculations that are based on a single condition.
- If the enemy champion is going to die from the base damage alone [without true damage being added] then the game calculates whole damage as "normal" while keeping statistics for the converted true damage
- If the enemy champion is not going to die from the base damage alone, then the true damage will be calculated as usual and shown correctly after applying
Damage value after resistance if you are above kill threshold:
(218.8575 - 21.88575[Conqueror damage]) * 0.741%[34.9 MR Sejuani] = 145.95606675
Shown as damage of 146[145.956] + 22[21.88575] -> Total of 168
Damage value after resistance if you are under kill threshold:
218.8575 * 0.741%[34.9 MR Seju] = 162.1734075
Shown as damage of 162 amplified magical damage [The case in the example video]
Revitalize bonus healing for Conqueror damage/heal value of 21.88575
The game actually splits these values for the damage/heal calculation and stats display value [Revitalize stats are bugged since god knows when]
3.39229125 [15.5% Revitalize bonus for the value of 21.88575]
Total heal value:
292.18035 [Empowered heal value]
+ 21.88575 [Conqueror damage/heal]
+ 3.39229125 [15.5% Revitalize bonus for the value of 21.88575]
The Total Bugged heal value of 450 happens because Sylas, while under 40% hp, is killing the enemy champion with his empowered W rank 3.
In this situation, we have a case of healing being increased to 1.5 times the intended amount so we will add to the "Empowered heal value" our "Bugged base heal value"
Bugged base heal value will have Revitalize applied to it with 5% bonus [Since the game now knows we are above 40% HP]
Bugged base heal value:
110 [Base value of heal for the rank 3 W when above 40% HP threshold]
+ 5.5 [5% Revitalize bonus for the value of 110 when above 40% HP threshold defined by Revitalize rune]
+ 16.485 [0.35% bonus AP scaling for the rank 3 W. Total AP: 47.1]
+ 0.82425 [5% Revitalize bonus for the value of 16.485]
Total Bugged heal value:
317.45839125 + 132.80925 = 450.26764125
Shown as health gain of 450 [The case in the example video]
