KAYN

The Shadow Reaper

Top Jungle

A peerless practitioner of lethal shadow magic, Shieda Kayn battles to achieve his true destiny—to one day lead the Order of Shadow into a new era of Ionian supremacy. He wields the sentient darkin weapon Rhaast, undeterred by its creeping corruption of his body and mind. There are only two possible outcomes: either Kayn bends the weapon to his will... or the malevolent blade consumes him completely, paving the way for the destruction of all Runeterra.

- Damage amp (Shadow Assassin, 52-66% for 3 s)798G
Combat only: 50%
Effects that only work in combat or under a condition are counted as active half the time. The same rule applies to every rune and spell.
Read as a similar price
Effects without a price are read as the closest existing formula: vision as avoiding a gank death (half an escape tool's chance), blocking attacks or projectiles as a shield for the same time, untargetable time (invisibility, etc.) as crowd control on the enemy, range as the move speed of the approach distance saved, experience as gold (1 = 0.5 gold), and stolen or reduced enemy stats as stats (or defense) you gain.
- Physical damage1,579G
Combat only: 50%
Effects that only work in combat or under a condition are counted as active half the time. The same rule applies to every rune and spell.
At most once per 8s
Effects that re-trigger on attacks are counted at most once every 8 seconds, since a single fight only allows so many procs.
Damage valued like healing
Damage to an enemy is valued like healing yourself the same amount, priced with the health regen rate.
Skill ranks from level
A champion's ability values depend on rank, so rank is derived from level. The ultimate ranks up at levels 5 / 9 / 13. Remaining points go to abilities 1 → 2 → 3 in turn (1 / 0 / 0 at level 1, 4 / 4 / 4 at level 15). Which ability to max first is a judgement call, so every champion uses the same order. Abilities with a different number of ranks (such as Jayce's 5) follow the same rule, raising the lowest-ranked ability one point at a time; an ability learned from level 1 starts at rank 1.
- Physical damage1,250G
- 90% slow (decaying)512G
Combat only: 50%
Effects that only work in combat or under a condition are counted as active half the time. The same rule applies to every rune and spell.
Survival factor
Moving faster by some % is counted as that % more effective health, since speed lets you dodge and escape. Value = median max health × the speed gain × the health price.
Move speed % as flat
Move speed % is converted to flat move speed against the median base speed of 350, then priced at the flat rate.
Champion median
Values that depend on the champion, such as health, use the median of all champions at level 1 and level 15.

Converted to gold with the same formula as runes. These are bare values, so ratios such as AP grow with the build you make in the Build Lab. Dashes are counted in Mobility as a dash count. Tap a row to see the formula and assumptions.
