After you do this then push the left-most block
like always and go down the staircase. In this basement you will get
probably the most valuable item in the game which is the red ring. With
this ring, the damage you take from enemies will be reduced to a fourth
meaning it will be really hard for you to die now! Sometimes this thing
is so effective that an enemy will hit you and you will simply not get
hurt at all. Talk about effective! That and Link will turn red for the
rest of the game if that matters to you. After leaving the basement, go
down two rooms, then left a room watching out for the Gels, then up,
then left a room.
