MHUR TUNING OPTIMIZER

What this is

The MHUR Tuning Optimizer is a fan-made tool for My Hero Ultra Rumble that helps you figure out which costume best fits the Tuning effects you actually want, instead of manually checking dozens of costumes one at a time. Pick a character, choose the effects you're after — Max HP+, Quirk Skill Attack Power+, a specific Special Tuning, whatever — and it ranks every costume by how well it can actually fit them, slot by slot, restrictions and all.

Pages

• Optimizer — the main tool. Pick a character, choose desired effects, see best costumes for what you want.
• Build Editor — create a build by selecting the tunings for a costume and see the exact status bonuses you get total.
• My Builds — builds you've saved, stored only in this browser unless you publish them.
• Community Builds — builds anyone has published, searchable and filterable by character/tag.

How the numbers work

Tuning level values come from community-sourced data on the effects shown in-game, cross-checked against a public good-to-knows writeup. Percentage-based stats (Attack Power+, Defense+, Reload+, Speed+) stack multiplicatively when you equip more than one — two +2.5% cards compound to +5.0625%, not a flat +5%. Flat stats (jump height, Max HP+/GP+) just add up directly. The "📊 Tuning Totals" button on a build shows the actual combined total for everything currently equipped, Fixer stat doubling included.

Known limitations

• Per-slot enhancement level isn't tracked — totals assume every filled slot is already at its own max level for that slot (3 normally, 4 for Hero/Villain-restricted slots).
• Special Tuning totals aren't included in the Tuning Totals breakdown — I figured this would be redundant as most people already know what they do. However enough ask I will implement it.
• This is a fan project with no affiliation to Bandai Namco or the My Hero Ultra Rumble team — effect values are community-sourced and may drift from the live game after balance updates in which I will try my best to update them as quickly as I can.
