Criptograma Charts are the coded symbol sheets that open Criptograma Chests. Every chest needs two of its own, so you hunt down 30 charts in all to empty the 15 chests on Yara.
Every chart is near the Criptograma Chest it belongs to. Start at the chest, which you can spot by its wind chimes, then look for Guerrilla Sigils painted on walls and rocks around it. Follow those markings and they lead you to the charts.
A chest stays locked until you hold both of its charts. With the pair in hand, go back to the chest and open it. There are 30 charts for 15 chests: four chests each in Madrugada, Valle De Oro and El Este, two in Esperanza and one on Isla Santuario.
The charts themselves are the key, not the prize. Opening the chest gives you unique gear and fills in both charts on your collection list.
EsperanzaEsperanza is Yara's capital and largest city, and the heart of Castillo's regime. It is under martial law, most open streets are restricted areas, and the story only really sends you there near the end.
