New Enchantment "Blow Absorption"

An idea for a new armor enchantment named "Blow Absorption". (not a final name) Not sure of how it can obtained. I guess, it can be obtained anywhere (enchantment table, fishing etc.).

A new leggings enchantment. This enchantment makes you take less damage from explosions but in return it increases a range that knocks you back from a place of explosion. (Possible replacement for "Blast Protection"?) Doesn't conflict with any other enchantment.

Has 3 levels which increase knockback up to 140% (1 lvl.), up to 180% (2 lvl.), and up to 250% on the 3rd lvl.
