Tower Collapse
See Ganon for the boss fight at the end of Collapse.
──── Collapse Skip (from outside)
Child - Instaclip HESS void warp
The void warp requires more than 2 hearts, because you take 1 heart from voiding and 1 heart from fall damage.
Child - Lower HESS setup
The void warp requires more than 2 hearts, because you take 1 heart from voiding and 1 heart from fall damage.
This is the older method of the Child rock HESS void warp, which stands near the first iron bar door and uses a pause buffered Zelda targeting setup to get the clip angle. This setup requires the Hold Targeting setting. It is slower than the instaclip which is done from the top of tower, but it can be done as an easier strat or as a backup for failing instaclip.
Adult - Bomb void warp
Video below explains initial (coming from Ganondorf fight) and non-initial setups, and movement after the void warp. The initial setup won't work coming from other parts of collapse, such as if you wrong warp from Deku Tree then exit the collapse rocks room. The movement out of bounds (in the unloaded tower) is also different if you're coming from elsewhere.
This strat requires 3 hearts in order to not die to the void warp and fall damage. If you get hit by a rock while setting up and you're lower than 3 hearts, you have to die to get your health back.
Non-initial position
This is a quick reference video showing just the fast non-initial position for getting onto the ledge on top of the tower.
