New Boss (the Parasite)

the Parasite would have 200 hp, but you could only kill it with ranged weapons, because if you touch it, you will get a negative effect (poison, weakness, damage etc).

Good Posions would make him take 10hp of damage, but neutral and negative will give him 10hp

The Parasite would not be able to attack you directly, but he would summon Parasite Worms to attack you.

On half way through killing it the parasite will recieve 30% less damage (except for posions) and will infect mobs around it to go and attack you with %125 their original health and 75% their damage. After killing it,  a parasite's skin would remain, which you can place down, and if you throw an item on to it, it will turn into something else on the next day, for example 9 coal/charcoal turns into 1 diamond. To summon it put the shape of a 2 block tall beacon replace it with sculk moss (idk what its called) and the top make it a paraxite (droped by parasite worms that now appear on the sculk biome (disclaimer parasite has nothing to do with warden, k) also warden is to op so make it only for ancient cities.
