SENNA

the Redeemer

Top Jungle

Cursed from childhood to be haunted by the supernatural Black Mist, Senna joined a sacred order known as the Sentinels of Light, and fiercely fought back—only to be killed, her soul imprisoned in a lantern by the cruel specter Thresh. But refusing to lose hope, within the lantern Senna learned to use the Mist, and reemerged to new life, forever changed. Now wielding darkness along with light, Senna seeks to end the Black Mist by turning it against itself—with every blast of her relic weapon, redeeming the souls lost within.

AttackDefenseMobility

- Physical damage (2 hits: 1-10% current health)597G
- Physical damage (Relic Cannon +10)49G
- Move speed (10% of the target's)171G
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.
Continuous values at midpoint
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.
1 attack per second
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.
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.
Assumed duration
Effects whose duration or seconds aren't stated use one assumed value per kind: 2 seconds for move speed and slows, 0.75 seconds for knockbacks, 1 second for fears, and 90 seconds for a reuse interval. Transformations with no stated duration (Swain's demon form lasts as long as he keeps damaging enemy champions) are assumed to last 10 seconds and counted with the ultimate-transformation rule (duration ÷ cooldown).
Champion median
Values that depend on the champion, such as health, use the median of all champions at level 1 and level 15.
- Physical damage368G
- Slow102G
- Heal (allied champion)342G
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.
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 damage1,023G
- Crowd control (root)1,774G
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.
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.

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. The Combat Power from skills also includes the stack estimate (ABSOLUTION).
