Description
Will automatically change you size depending on health, as well as entities.
Not toggleable.
Adds 5 items.
Shrinker: Shrinks you a small amount
Grower: Grows you a small amount if you have xp. Removes 1 level per use.
Lock: Right clicking an entity will replace their main hand item with this, and will stop their size from changing when their health changes.
Stealer: Steals half of an entity's size, and multiplies yours.
Giver: Same as stealer, but vica versa.
Recipes:
Shrinker and grower are arrow shapes of redstone blocks and emerald blocks, respectively.
Lock is a upsidedown t shape of gold bars, with a iron bar at the top.
Stealer is glass in a circle, with no centre or corners.
Giver is the same, just with stained glass.
I would reccomend NEI.
Enchantments.
Sizelocked: Helmet enchant, acts same as lock, but without taking up mainhand.
Misc.
Holding a grower or shrinker in main or off-hand will act the same as a lock.
Holding lock in offhand will not stop damage shrinking.
Made in MCreator.
Requires pehkui.
If you are looking for something similar to this, I made a lifesteal mod, but it will change your size depending on health.
