The Herta: Character promotion materials & levels
The Herta has these reference forms: The Herta (Ice · Erudition). Choose a form, then current and target promotion stages to see the direct material totals and unmodified level values.
Promotion costs exclude leveling XP, trace upgrades, Light Cones and relics. Stats use promotion base + growth × (level − 1) within the selected stage’s level range. Enter the selected form’s actual current progress; the planner compares one form at a time and never adds alternative-form tables together.
Using this reference
Choose the form of The Herta before selecting promotion and level. The allowed level range follows the target promotion, so changing the target may also move the displayed level. Materials cover the promotions between current and target; the stat projection describes the selected target and level.
Compare two forms at matching settings to avoid mixing promotion gains with a form difference. The listed materials and base stats do not include the rest of a build, such as equipment or additional progression systems.
