Entity-specific checks
Riot confirms the old mastery system returns. This page presents the Offense, Defense and Utility trees from a 3.15.5 historical snapshot; exact launch values still need client verification.
The current historical record contains 57 nodes with tree, row, column, maximum points and prerequisite relationships.
No. The nodes are historical references, and the eight general setup pages remain reading directions rather than best launch pages.
No. The data pipeline forbids modern-system substitution; uncertain Classic fields remain pending.
