Four new boss suggestions

Here's a few boss ideas I've been thinking about.

●Dragonfly

The dragonfly would be a flying boss, it could perform airborn attacks for a certain amount of time, then land and stay grounded(😁) for a certain amount of time. In the air it could attack with bites, swoops, dive bombs, and perhaps it could pick up pebbles and drop them on players, when on land it could bite, ram, perform a tail swing, and use it's wings to create a gust of wind that blows players back. Drops dragonfly chunks, dragonfly head, and dragonfly wings. You could craft a set of ranger armor out of it, as well as a great bow.

●Crab

The crab would be a powerful boss with a lot of defense. One of it's claws could be larger then the other, and that claw could do more damage, but attack slower. Fought in a swampy area with pools of water around, deep enough for the crab to be submerged, but not so deep that players can swim above the crab, out of it's reach. Can attack with claw pinches, body slams, raming, hurling pebble, and slaming it's claws down to creat shockwaves that shoots forwards. Under water, it's shockwaves could be larger. Could also be able to block. Drops crab claw, crab shell, and crab legs. Can craft a suit of fighter armor out of it, as well as a heavy shield and a spear.

●Centipede

A large boss fought in a underground cavern. It's length gives it a impressive reach with it's attacks, which are bites, tail whips, body slams, burrowing into the ground and erupting upwards somewhere else, spitting sour acid, which inflicts tang buildup, it could summon some much smaller centipedlings to help it. At some point, it could burrowing into the ground, stick it's head out of the cave's ceiling, and spit large amounts of sour acid down on the players. Drops centipede mandible, centipede chunks, and centipede gland. You can craft a set of rogue armor out of it, and a pair of sickles.

●O.G.R.R Mant

The O.G.R.R Mant has a elemental effect, like all O.G.R.R creatures, it has three combat phases, and every time it switches to a different phase, it changes elements, having fresh in one, sour in another, and spicy in the last. Attacks include punches, slams, close-range elemental blasts, elemental bombs, summon mini mants, could also counter, and it could inflict a buildup effect to all players near it.(what effect depends on what element it currently has) Drops mant head mant claw, mant chunks, and buff'in glands. Can craft a set of mage armor out of it, and a two-handed club.

These are my ideas for bosses, please let me know what you think, if something should be changed, something added, or if you have more boss ideas.
