Drakomire

It is a ground spawn at the Solar Pillar, so it only exists once the cultist has fallen and the pillars are up. There is no summon item and no way to meet one elsewhere. A Drakanian sometimes rides in on one, which turns the pair into a single target running both movesets at once.

It stops, throws out a spread of solar flares, then waits a while before repeating. Every hit you land cuts that wait short, so grazing one with a weak weapon while you deal with something else makes it fire far more often than ignoring it would. Commit or leave it alone, but do not chip at it. A ceiling on how many flares can hang in the air keeps it from burying you outright.

Ground level puts you in front of chargers and diving Corites. Flying high brings Crawltipedes, which are worse. The compromise is a thin platform walkway a short way above the ground: you count as standing, so Crawltipedes ignore you, and the chargers pass underneath where you can shoot down at them. Selenians are what ruins it, since they pull your attention sideways while flares are already in the air.
