Eternal Feast

The Eternal Feast enchantment in a treasure enchantment applicable to swords. When applied, the user will gain some hunger whenever they kill an entity, depending on the level. In particular, the user gains 2 hunger () per kill, per level, see the table below

Eternal Feast Level	Hunger Gained Per Kill
1	2 ()
2	4 ()
3	6 ()

If a sword is cheated to have a higher level of Eternal Feast than the expected maximum (level 3), this pattern continues. For example, a level 5 Eternal Feast will award the player 10 () hunger per entity killed.

Note that Eternal Feast does not award any saturation per kill, only hunger.
