Ian Issa is one of the temple exploration ruins in The Legend of Zelda: Tears of the Kingdom. Many players are unclear about this location. This site brings the location strategy of Ian Issa in The Legend of Zelda: Tears of the Kingdom.
1. After entering the temple, go north and pick up [Rusty Two-Handed Sword]. Use the L key to select and use the leftover build to attach the large rock to the sword.
2. Use the rock-mounted sword to smash the brittle rocks blocking the way, then continue forward.
3. Note that the fragile rocks as shown in the picture below can be destroyed in this temple. If you destroy one of them, you can get the treasure chest placed above it.
4. Enter the next room and pick up the flame fruit and [Old Wooden Bow]. With the bow set up, press the cross key and the right joystick to select the flame fruit and mount the flame fruit on the arrow.
5. Look above the east wall and shoot the flammable vines with an arrow attached to the flame fruit. The treasure chest will fall and pick up the small key.
6. Take the stairs to the north of the area where the rock pillar is and use the small key to open the green door. Then climb up the ladder and continue forward to encounter an enemy golem. You can quickly defeat the golem by hitting it with a rock-attached weapon. Destroy the rock wall to the north and continue moving forward. Investigate the green crest on the altar to obtain the "Light of Blessing."
