👥 Build Your Roster

Head to My Roster and select every unit you own. Your roster is the foundation of everything else on this site, so the more units you add, the more accurate and personalised your team builds will be!

2
⚡ Build a Team

Head to the Team Builder tab and drag units from your box into the team slots. The sidebar shows equip coverage, barriers, and arts gen stacking, while per-unit totals appear below each slot. Expand the Team Effects cards to see the full breakdown!

🔍 Filter Through the Compendiums

Use the Units and Equips compendiums to search for exactly what you're looking for. With a huge range of custom tags unique to GS Companion, you can filter by role, buff type, ailment, element and more — finding the exact kit you need with ease. You can also compare up to 4 equips side by side.
