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.

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 % is converted to flat move speed against the median base speed of 350, then priced at the flat rate.

Values that vary continuously with the target's or your own state (damage rising with the target's missing health or with charge time, attack speed rising with your missing health, etc.) are taken at the midpoint of min and max, the same idea as assuming 50% missing health.

Values that depend on the champion, such as health, use the median of all champions at level 1 and level 15.

Effects that re-trigger on attacks are counted at most once every 8 seconds, since a single fight only allows so many procs.

Damage to an enemy is valued like healing yourself the same amount, priced with the health regen rate.

Bonuses that depend on the target's or your own state (extra effects on burning enemies, detonating marks, "if already ..." bonuses) and effects tied to a position or situation (near turrets, in brush, moving toward a low-health ally) assume the condition holds 50% of the time, so they count at half. Effects triggered by your own death are assumed once per 90 seconds, like takedowns. Empowerments spent by another ability (such as Karma's Mantra) count the bonus once per that ability's cooldown.

Effects on every Nth attack (every 3rd attack, etc.) assume 1 attack per second and are turned into seconds (every 3rd attack = once per 3 seconds). The 8-second floor for attack-triggered effects still applies.

A 15-minute match is assumed to have 10 fights. Shields and damage blocks that work once per fight are counted as extra health in every fight.

Crowd control that stops the enemy (stun, charm, etc.) is treated as time you aren't being hit. A fight is assumed to last 10 s, so it counts as holding seconds ÷ 10 × median max health in extra health each fight. Uses are capped like shields: the fewer of cooldown uses and fights.

One kill or assist every 90 seconds (10 in a 15-minute match) is assumed. Uncapped stacks count half of that as the mid-match average.

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.
