How the HP numbers are counted

Most bosses are one creature. For the rest we add up the parts the way the wiki does: The Twins = Retinazer + Spazmatism; Skeletron Prime = head + four limbs; Golem = head + body + both fists; Moon Lord = head + core + both hands; the Flying Dutchman = its four cannons; the Eater of Worlds = all body segments. Skeletron and the Brain of Cthulhu show the main body only (the hands and Creepers are extra). Dark Mage and Ogre show their lowest Old One's Army tier.
