Usage

By holding right click the player can raise the amethyst shield. After five game ticks, or 0.25 seconds, this makes attacks in front of the player deal no damage, as they are blocked. Attacks of three damage or more deal equal durability damage. 

When the shield is held in the main or off-hand, it offers extra health. Provided the player is not starving, holding an Amethyst shield will gradually increase health up to an extra row of heart (additional 10 hearts - 20 HP). This increase is slow if the player has less than full food-saturation. (When fully fed, 0.5 hearts are gained ~1second).

When unequipping the shield, all extra hearts will be instantly lost and cannot be returned until the item is re-equipped (with the normal delay to build up those hearts which varies with food). Unequipping the shield has a visual effect similar to taking damage, but the player does not sustain damage from doing so.
