Jinchuriki progression

Before consuming a soul

Stages 1 and 2

1. With the sealer ready beside you, consume the soul. The helper must cast Binding Seal during the immobilized window. Success grants Stage 1.
2. Activate the Jinchuriki mode repeatedly. The main guide observed Stage 2 after 31 activations on two accounts; it explicitly does not establish a universal minimum.

Stage 3 and the Beast Key

1. With Stage 2 active, low health or an attempted grip can trigger the uncontrolled third stage. It is chance-based.
2. Enter Stage 3 several times to weaken the seal. A Senju with Wood Suppression can apply three Wood stacks and Wood Seal to end berserk before its fatal expiry.
3. Speak to Keytora, the frog statue reached from Rosemary Pit. Once eligible, obtain the Beast Key.

Stage 4: controlled cloak

1. Go to the meditation pillar near The Expanse waterfall. Open K and choose Meditate on the pillar.
2. Speak to the beast inside the subconscious and use the key to begin its trial.
3. Defeat the inner beast and speak to it again to leave with the controlled cloak. A failed attempt costs Life Force and requires an age-up before replacing the key.
