Combat Level Calculator
Formula: XP = level²
How Combat XP Works

Each level requires XP equal to your current level squared. For example, going from level 200 to 201 costs 200² = 40,000 XP. The higher your level, the more XP each step takes.

Formula: XP = level² · Supports shards & cola boost
Cola Boost+20% XP to all shards
Shard XP Values

Lv.1 = 4,000 XP · Lv.2 = 20,000 XP · Lv.3 = 100,000 XP. With Cola (+20%): Lv.1 = 4,800 · Lv.2 = 24,000 · Lv.3 = 120,000. Trade fruits at Blacksmith for 1,000 fragments each.

Cola Buff+20% XP per MF run
How Haki XP Works

Haki uses a fixed XP table (not level²). XP is earned by running Marineford 1 (130 XP/run) or Marineford 2 (260 XP/run). Cola Buff adds +20% XP per run. Ice Shards drop 12 per full MF run.
