Pick which gear pieces you want to add charms to. Each piece has charm slots — set the level you're at now and the level you want to reach. The calculator shows you all the materials you'll need.

Each gear piece (like your helmet or armor) has up to 3 charm slots. You can upgrade each slot to boost your chief's stats. You can work on them one at a time or all at once.

Charms use Guide Books, Designs, and Secret Materials. Higher charm levels need more of each — the calculator totals it all up for you.

Enter how many materials you already own. The calculator will subtract those and show you exactly what you still need to collect.

Yes! Your charm levels and inventory are saved in your browser. Everything will be right where you left it next time you visit.
