The enchanted golden apple provides Absorption IV for 2 minutes (providing points of absorption health), Regeneration II ( every 25 ticks,  × 0.4 per second) for 20 seconds (long enough to heal  points of damage), Fire Resistance I for 5 minutes and Resistance I (20% reduced damage from all sources except the void) for 5 minutes.

Golden apples can be eaten even when the player's hunger bar is full.
