YUUMI

the Magical Cat

SupportBWR48.2%

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.

The combos in the tables below, grouped by shape; not a ranking or a verdict. Each item goes to the family its stats are worth the most gold in, and a shape is how many of the 3 core items fall in each family. Effects (passives) are not counted, and items without stats are left out. Runes are grouped by keystone and the most common tree among the rest. The icons show the most common combo of each shape. A shape at 10% or more counts as a pattern; shapes under 3% get no card. Less common item families are families whose items appear in under 10% of the Chinese combos but do show up in overseas guides or streamer and pro builds. Their icons are separate item options seen in those sources, not one build. Families are listed by how many sources they appear in.

Assumptions

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.

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.
