At Lake Hylia the path to the dungeon leads over deep water. If you still lack swimming equipment, first look for the small cave in the northwestern part of the lake area. Their location within this recognizable area will help you more reliably than a fixed distance from Hyrule Castle on the world map.
Obtain Zora’s Flippers
There is a sleeping Zora in the cave with five ghosts in front of him. First, make sure you have a supply of bombs; If you are missing any, also check the pots in the cave. Eliminate the ghosts with the explosions. Keep your distance from the bomb and only set the next explosive device once you have assessed the previous hit.
When all five ghosts have disappeared, Zora awakens. Talk to him and collect the Zora’s Flippers. You can now swim through deep water areas. Leave the cave, explore the previously inaccessible banks and head for the entrance to the Frozen Grotto. The fins also remain useful for other water hazards in Hyrule.
Plan with the ice
In the ice dungeon, you slide further across frozen surfaces instead of stopping normally on every field. Before moving, look at where an obstacle ends the slide. Work from these handholds to the next entrance. Trying to turn too quickly won’t solve the problem if it means stopping in the middle of the ice.
Movable ice blocks and appropriate equipment change these paths. For example, you can create an obstacle yourself with a Cane of Somaria that has already been found. This is an additional possibility; You don’t have to search for this exact item in the overworld before every attempt. First, examine the blocks and switches present in the room. Switches can change ice and water surfaces and thereby open up new paths.
A Fire Rod helps with ice blocks that contain an object or enemy if you already have it. Find the keys and connections in the generated combat areas and return to the locked entrances. Fill up your health in front of the boss chamber and have a suitable weapon ready with which you can attack quickly after a change of location.
Defeat Wizzroboe
Wizzroboe, Wizzroboe, disappears and reappears elsewhere. Use his visible phases for hits. Keep an eye on the markings on the ground: they indicate where ice attacks will hit. Leave a marked space before attempting to force an additional hit.
The summoned ice opponents can block paths and ice other parts of the arena. Get them out of the way if they surround you or block access to the boss. Then move back to the visible Wizzroboe. A clear way back is more valuable than the opportunity to stop very close to him.
Even in the stronger phase, the rule remains the same: avoid ground warnings, eliminate disturbing companions and attack after it reappears. After winning you will receive Oboe and Heart Container. Use your fins to return to waterholes that were previously inaccessible before moving on to the next open instrument.
