Hero intelligence
Last Z Heroes Database and Progression Guide
The hero database organizes the roster into searchable planning information so commanders can compare faction, role, season, and progression without losing their personal stats.
Use tiers as guidance
Tier labels are strategy guidance, not an official Last Z ranking. Formation fit, skill investment, stars, equipment, troop type, and season can outweigh a general tier.
Plan a target
Set target power, level, stars, and equipment rarity to turn the database into a progression checklist instead of a static hero list.
