Carrie Fernandez unlock guide: unite the Custos glyphs

Quick answer: unite all three Custos glyphs into Trinum Custodem

Carrie Fernandez unlocks when all three Custos glyphs are maxed in the same run and united into Trinum Custodem. Cornell starts with Dextro Custos and can offer the remaining Custos weapons through his level-up choices.

Who this guide is for

• You want Carrie's exact unlock condition.
• You need to know what “fully evolve” means for the Custos glyphs.
• Your three glyphs are not uniting into Trinum Custodem.

Unlock steps

1. Unlock Cornell and start a run as him.
2. Obtain Dextro Custos, Sinestro Custos, and Centralis Custos in the same run.
3. Raise all three weapons to their maximum level of 6.
4. Open an evolution-eligible chest to unite them into Trinum Custodem.
5. Confirm that Carrie Fernandez is unlocked.

This is a three-weapon union. Maxing the glyphs across separate runs does not complete the union requirement.

If the union does not appear

• Confirm that all three Custos weapons are in the same loadout.
• Confirm that each weapon reached level 6.
• Open an evolution-eligible chest after all three are ready.
• Use Cornell's level-up choices to collect the full set.
