- +20% move speed (near turrets)1,367G
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.
Conditional bonus: 50%
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.
Champion median
Values that depend on the champion, such as health, use the median of all champions at level 1 and level 15.
- Turret shot magic damage493G
- Turret beam magic damage (max charge)210G
- Turret health (soaks attacks)183G
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.
Summons attack once per second
A summon's attacks (Tibbers, turrets, plants, clones, etc.) are assumed to hit the same target once per second unless an attack speed is given, for as long as the summon lasts (5 seconds if not stated, at most the 10-second fight length). Summons are counted once per cooldown (at most once every 8 seconds), with the usual combat-only 50%. A summon's health is counted like a shield for the attacks it soaks, assuming it's targeted 50% of the time. Clones that mimic the champion's abilities are assumed to copy each one once while they last. Buffs to a summon are applied to that summon's share.

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.
One fight per 90s
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.
Champion median
Values that depend on the champion, such as health, use the median of all champions at level 1 and level 15.
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.

One fight per 90s
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.
Fight length: 10 s
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.

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.
