Stalblind

Stalbind is the final boss of the Thieves' Hideout first appearing in A Link Between Worlds, and the deceased Lorulean counterpart of Blind the Thief. He can only be reachable when the Thief Girl is returned to the entrance of the dungeon.

Location and Access
Despite Stalbind's lair being located directly adjacent to the entrance of the dungeon, you can only reach it when escaping with the Thief girl. Like any other dungeon, you will need the Big Key too.

It is fought inside a dark room with a rectangular platform, surrounded by an endless pit.

Strategy
When Link enters the room where Stalbind resides, the boss will rush against him with his sword and shield. Link must merge (become a drawing) into the shield so the boss will be confused and will try to find him in the room. In that moment, Link must exit the wall and slash him with his sword. After sustaining enough damage, he will throw away the shield, and attack Link with various powerful slashes. In this phase, he is vulnerable to most weapons in Link's arsenal, but can be hard to hit because of his relentless attacks. In the final phase of the fight, Stalbind's head will detach itself from his body, and attempt to attack him as the body continues slashing. This makes him more formidable, but a few more sword hits will eventually slay the boss. After his defeat, the exit of the dungeon is opened, and the Thief Girl takes Link to where she hid Sage Osfala's painting.
