Explore tools & guides

Each page is focused on a single job: codes, tier list, calculator, guides, and reference info.

More tools

Inspired by the reference hub’s “More Tools” section: small utilities to help you plan comps, costs, and progression decisions.

Resources & FAQ

Why this hub works

UTD is a game of small advantages: efficient team building, smart upgrade timing, and avoiding wasted Gems. Most players fall behind not because of skill, but because they spend resources without a plan. This site is structured to keep decisions simple: get codes, check tier list, calculate DPS, then follow a guide.

Use it like a workflow. If you are new, follow the Quick start checklist. If you are returning after an update, re-check Codes, then scan Tier List changes before spending Gems.
