Warden's ears/horns

The Warden tempts many to fight against him, it is a great challenge, however it does not generate any reward for the arduous battle.
That the ears / horns of him more than decoration or trophy are enhancers or additives for the Netherite armor:
If we fuse them to the Netherite helmet that grants Sonic Boom's power:
•Every time the Sonic Boom is used we lose 50% of life.
•You would have to repeatedly press a button to "charge" it
•For each use there is a "cool down" time
•The effectiveness against players that is 100%
