Cogni pets

Cogni is 41 pets. Each one you own adds the genus's Owned Effect — HP +30, Critical Hit +2, Might +1 at Pet Insight 3; all 41 at the top add HP +1,230, Critical Hit +82, Might +41. All its pets at the top raise Cogni Insight to level 7; 2,090 analyses with nothing locked take it on to 10. Its slot 4 can roll Status Effect Chance, Damage Boost, Critical Damage Boost, Endurance Penetration, Regeneration Penetration, Cogni Damage Boost and PvE Damage Boost. 417 of the game's 521 bosses are Cogni, so its Cogni lines count against them.

All 41 pets at the top Pet Insight level give 41,000 EXP (1,000 each) — Cogni Insight 7, the highlighted row. From there: 2,090 analyses with nothing locked reach level 10, for 8,360 Cogni Soul Crystal (Bound) (or universal ones) and 2,090,000 Kinah. Each analysis gives 100 EXP (the window says "per slot"; players' reported spend fits once per analysis).

Level 10 pays the title Cogni to the Bone: equipped PvE Damage Tolerance +3.1%, Regeneration +1.6%; owned Front Attack +3.
