Apples+ adds new apples, like golden apples, each with their own effects. These are the apples I added with the associated effects:
Lapis Lazuli Apple - Night Vision, Luck
Redstone Apple - Haste
Copper Apple - Water Breathing
Iron Apple - Resistance
Diamond Apple - Speed, Absorption, Invisibility, Instant Health
Netherite Apple - Fire Resistance, Resistance, Regeneration, Absorption, Health Boost, Speed
