The first item in dungeon 7 will be changed from the Amulet (A whisp ring) to the Floor Tile (A level 2 ladder). As such, several rooms are having their floorplans changed and the number of red and yellow perma-bubbles has been reduced to compensate for the lack of protection. This affects the last three dungeons and the last HC Guantlet.
The Amulet has been moved to a hidden location on the overworld, where it can be purchased for 255 rupees (technically it can be purchased again and again like the Blue Ring; this is a shortcoming of the engine and cannot be avoided.
The Amulet feels like a 'reward' item for one of the money-or-life choices. Since I did not want to eliminate one of the other rewards, I decided to pair the Amulet with the HC on the overworld beach (it was stolen by a moblin). This makes it the only reward item the player can acquire without sacrificing a HC.
Also, the Fire Boomerang will be removed from the game and replaced with the Power Wand. The loss of stunning capability will be replaced with a massive boost of ranged firepower (4 damage before level 6) and the ability to harm Wizzrobes with this wand. In order to make the mechanic function, the Magic Book's damage boost will have to be reduced from 2 to 1 (is it really that noticeable?). With magic book, the wand will be more powerful than the Magic Sword for combat against enemies that do not block magic.
Finally, The Master Sword will be able to 'purify' negative bubbles, turning them into blue bubbles.
