Interactive calculator for planning weapon mastery progression in Throne & Liberty.

Live tool: https://stoopkid713.github.io/tl-mastery-planner/

What it does

• My Setup — toggle the 6 mastery buff sources (Amatori, Pal Synergy, Guild Blessing, Mastery Report, Golden Apple Pie, Black Anvil) and see live stats: total mastery %, token efficiency %, XP per token, multiplier vs bare.
• Weapon Planner — set weekly token burn and per-weapon current/target levels; see XP needed and weeks to complete at both your current buff stack and a full stack.
• Session Calc — input tokens to burn + starting level → levels gained, with a comparison table across 5 buff scenarios.
• Lookup Table — full L0–L200 per-level XP, cumulative XP, and XP-to-max.

Model

The XP curve is a quartic polynomial fitted to 23 measured data points from in-game screenshots across 5 anchor zones (L50–54, L80–84, L100–103, L130–134, L170–174). Max residual: ±0.077% across all measured points. The curve is weapon-type independent.

• Cost at L200: 19,253,922 XP
• Total XP to take a weapon from 0 → 200: 1,186,206,907 XP
• Base XP per base token (no buffs): 638.7 (derived from 31,935 base XP / 50 base tokens, Mutant Slaughterer dataset)

Formulas

Mastery XP   = Base_Mob_XP × (1 + Total_Mastery_Bonus%)
Tokens/kill  ≈ floor(Base_Tokens / (1 + Efficiency%))
XP per token = 638.7 × (1 + mastery%) × (1 + efficiency%)
