This is an old revision of the document!
It's time for the end chapter rundown of quest rule suggestions. There are not that many this time.
Quest→Rules→Combos→Link Drowns in Walkable Water
By default, Link just bumps against water like it is any other solid surface unless he has the flippers. However, this rule turns on a drowning mechanic similar to what happens in later Zelda games. You are warped to the place where you entered the screen and lose a quarter of a heart when drowning.
Quest→Rules→Combos→Use Old-Style Warp Detection
This uses an older style of warp combo detection that was present in 1.92 and older. The developers seem to recommend this setting be turned off since it only exists for backwards compatibility.
