Hey Mowzie, its me, 4Point! Remember me from some previous suggestions? well, i have an idea.
So, you have Items to harness Fire, via the sun, the Earth, via the Earth talisman, and the Water, via the Ice Crystal.
Now, this idea is about air, or, i should say, Lack of Air.
i welcome you to.... the Void Relic.
Harnessing the power of the void itself, it creates a vortex in front of the user by harnessing the power of the Void, and pulling in entities, banishing them into the Infinite pit of Despair (the void, DUH.) however, this miniature gateway to the shadow realm can only open for a few seconds at a time. however, a strange thing occurs when the user Sneaks whilst using this. instead of sucking things In, it spits the previously absorbed thing Out. i guess this occurs by generating a Input portal in the void instead of an Output portal.
"but wait!" you may ask, "How would you get it?". Heh. Heh. Heh.
the only thing that could harness the void is things that live In It.
this beast.... is the sacred, evil, Endarius Reaper.
A tall, slender humanoid carrying a Scythe fused with the Void Relic and lives in the Ender Islands.
Its main attacks consist of swinging its scythe about. but it has 2 incredibly powerful attacks.
Downwards Slash: a powerful downwards swing with its scythe. after this attack, its scythe gets stuck in the ground.
Void Exposure: Using the Void Relic, it sucks you in, putting you into a black realm with so much evil inside, you feel yourself begin to wither away. around 1.5 seconds after, it shoots you out into a wall.
no Weak Point is visible at first glance, as its made of the void itself, and has no eyes. Wait.... the scythe has an eye?!?! Apparently, the SCYTHE is the sentient thing here, and the Black Body is a mere puppet. however, when the scythe Strikes, the shadowy puppet's arm seems to vanish slightly, maybe holding your sword out while that happens prevents it from properly reforming...?
After completely destroying the shadowy figure, the Sentient Scythe is now more than happy to cut you into bloody pieces. The black figure completely dissapears and the Scythe begins to levitate.
Phase 2 Attacks:
The same as Phase 1, but more Hectic and Powerful.
Phase 2 Weak Spot:
Wait, why is the scythe the Sentient thing again.....?
The Scythe Spins rapidly, wide eyed, as the Relic begins to malfunction. soon, the relic begins to absorb, and the Scythe completely implodes.
See what its like when you have a LOT of time on your hands and a good imagination? i hope you like the idea, and i would be in awe if you put it in as a boss.
