Item Changes
These items eventually turned into birthstones.
Some healing items were changed completely or removed. These are the known removed items from an earlier design. Some of these items may have been changed into misc items for the final game, so it can be assumed that normal enemies were meant to drop healing items. The fact that many of them had similar effects (or none designed) is probably related to their removal.
Charms - Removed Curse
Small Hammer - Removed Petrify
Blue Candy - Unknown- Tree Root - Healed about 10 HP
Reptile Tongue - Healed about 10 HP- Scorpion Tail - Removed Poison
- Plant Stem - Removed Poison
Frog Legs - Heal about 30 HP
