Historical versus modern

Ability names are stable between historical 3.15.5 and modern 16.14.1, but that does not prove equal values or mechanics; launch verification is still pending.

Kog'Maw, the Mouth of the Abyss, is documented here from Riot's 3.15.5 historical snapshot. The ADC / Mid labels are an editorial navigation taxonomy, not launch-patch usage statistics.

Three-layer build system

Kog'Maw build evidence

Only layers with qualifying evidence are shown. Creator-tested and launch-verified layers are absent until their evidence gates pass.
