Tips for Academy Island
- !
This is endgame content (level 9000++). Come prepared with a fully upgraded sword, Conqueror Haki, and a strong clan. Underpowered players will struggle significantly.
- !
Academy Island has 1 boss: Anos. Check the Bosses Database for exact HP, drop tables, and spawn timers before farming.
- !
Every island has a teleporter (black-hole shape with a purple ring). Use it to fast-travel between islands without spending time sailing.
