Gameplay

 * Dominant hand option
 * An option for players to change their dominant hand on their player model
 * Dual wielding
 * Only the main hand can be used for attacking
 * Bows can be used even when something is in the other hand
 * The other hand is invisible in first person view when not holding something
 * Key to swap items between hands, which is by default
 * For example, if you have a pickaxe in your main hand and a torch in your other hand, right click places the torch
 * The off-hand slot is displayed next to the hotbar, on the off-hand side (left for right-hand players and vice versa)
 * Some attributes and enchantments will apply to the off-hand item, while others will not
 * Status effects
 * Levitation status effect
 * Received when player is hit by shulker projectiles
 * Makes player involuntarily float high into the air
 * Can be used to get to higher places


 * Listed as a negative effect due to the potential to kill from fall damage


 * Higher levels of levitation result in faster floating
 * For example, effect level 255 results in neither floating up nor down
 * Effect level 254 results in slow fall (similar to moon gravity)
 * Hitting the ground still results in the player receiving regular fall damage, if the player had fallen from a high enough elevation.
 * Glowing status effect
 * Received when players or mobs are hit by spectral arrows
 * Makes player's outline glow, seen even through non-transparent blocks
