S03 · Characters, classes and build systems

Current implementation: Persistent characters, eight lineages, 24 vocations, connected lattice, branches, sockets, circuits, masteries, oaths and imprints have executable paths.

Outstanding acceptance: Every earned progression path and long-run build niche still needs end-to-end viability evidence.

The four requirements below preserve the original release target. Their historic baseline is not used as a current completion score. This page does not mark the entire stream complete merely because related components are installed.

Reference

Requirement	Required deliverable	Acceptance standard
S03.01 · Implement persistent character and weapon development	Define XP sources, level milestones, proficiency, qualification, derived attributes and advancement records.	Practice counts are not presented as skill levels; all displayed progress changes a documented capability or statistic.
S03.02 · Implement eight lineages and 24 Floor 1 vocations	Create advancement trials, resource engines, role configurations, counterplay and primary/auxiliary boundaries.	Each vocation has credible offensive, defensive and supportive configurations plus evaluated hybrid and solo uses at comparable investment.
S03.03 · Implement lattice and technique branches	Author effect-backed nodes, prerequisites, active capacities, keystones, skill-specific transformations and build previews.	Every selectable node changes executable rules; every stated disadvantage is real; no decorative or undefined unlocks appear.
S03.04 · Implement runes, imprints, masteries and oaths	Define acquisition, crafting, equipping, capacity, trigger origin, conflict rules and reconfiguration.	The layers do different jobs; their combined resource and trigger behavior is tested, including death, loadout changes and copies.
