JAYCE

the Defender of Tomorrow

Top Jungle

Jayce Talis is a brilliant inventor who, along with his friend Viktor, made the first great discoveries in the field of hextech. Celebrated across Piltover, he tries to live up to his reputation as "the Man of Progress," but often struggles with the expectations placed upon him. Because of this, Jayce has begun to see the ways in which his invention has furthered the division between Piltover and Zaun—and armed with his hextech hammer, he stands ready to defend tomorrow.

AttackDefenseMobility

- Move speed (on transform)183G
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.
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.
Champion median
Values that depend on the champion, such as health, use the median of all champions at level 1 and level 15.
- Physical damage (To the Skies!, Mercury Hammer form)666G
- Physical damage (Shock Blast, Mercury Cannon form)1,237G
- Slow (To the Skies!, Mercury Hammer form)470G
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.
Forms split 50/50
Champions who switch forms (Jayce, Nidalee, Gnar's Mini and Mega) are assumed to spend half the match in each form, so both forms' abilities count at 50%. Hwei picks one of 3 spells per cast, so each of the 3 counts at 1/3. Champions who pick one form for good (Kayn) count only the higher-valued form.
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.
- Magic damage (Mercury Hammer form, over 4s)868G
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.

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.
