Unlock and upgrade
- Complete each hand-in. A trainer turning black indicates that its step registered.
- After all four, receive Burrow. It works on grass and trees; other surfaces can prevent activation.
- For Poison Burrow, collect ten Poison Gems and use the upgrade dialogue with a Zetsu trainer. The video allows any trainer; the written guide specifically points to Rose Bay.
What changes
Burrow improves recovery underground and adds short teleports. The upgrade leaves damaging poison when teleporting.
