100% Water Temple

RBA Route Idea for 100% (Inside Water Temple)

After getting the small key after Longshot:
SW
Go into middle pillar and get GS
Mainroom lowest floor
Get Bottle on B over BGS in waterpool (ice arrow on c Right, and you dont need the fish anymore)
Get the remaining GS
SW (don't equip bgs, because when you start again you have empty B)
SS to Ledge
Enter Boss Room
Kill Morpha with hammer
Get HC
Get Down A
Do CS skip with Ocarina + FW (wait until ocarina auto cancels, run into middle of warp, press fw) and warp to fire.
