Updated 2026-10-07 · checked against Global launch (client 2.0.5.0)

Cogni is one of the five pet species in AION 2, with 41 pets. Every Cogni monster you can fight is a Cogni pet you can unlock by collecting its souls, and each one taken to level 3 adds its bonus to your whole account on that server.

Its Genus Insight runs on blue Cogni soul crystals.

Cogni Genus Insight

Each analysis costs 4 Cogni soul crystals (generic soul crystals work too) and 1,000 Kina, and rolls a stat into every open slot. Locking a roll you want to keep costs more with each lock: 8 crystals + 2,000 Kina → 16 crystals + 4,000 Kina → 36 crystals + 9,000 Kina → 76 crystals + 19,000 Kina → 156 crystals + 39,000 Kina → 236 crystals + 59,000 Kina → 316 crystals + 79,000 Kina → 396 crystals + 99,000 Kina.

Insight levels

Slot n opens at Insight level n, so all nine are open from level 9. Higher levels also roll better grades:
