YUUMI

the Magical Cat

Top Jungle

A magical cat from Bandle City, Yuumi was once the familiar of a yordle enchantress, Norra. When her master mysteriously disappeared, Yuumi became the Keeper of Norra's sentient Book of Thresholds, traveling through portals in its pages to search for her. Yearning for affection, Yuumi seeks friendly companions to partner with on her journey, protecting them with luminous shields and fierce resolve. While Book strives to keep her on task, Yuumi is often drawn to worldly comforts, such as naps and fish. In the end, however, she always returns to her quest to find her friend.

- Self-heal on hit (also to the attached ally)1,628G
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.
You and one ally
Heals and shields that also reach an ally are counted for two people: you and one ally.
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.
- Magic damage1,086G
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.

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.

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.
