How to unlock the SPF 1000 achievement in Lovers in a Dangerous Spacetime - Definitive Guide
Once you have his health quite low, give yourself some space, then when he fires the flare move so you form a right angle between him, the flare, and you. Shoot the ball a lot with a rapid fire weapon and all the solar flares will be enough to break his ice shield and take his health to zero.
Killing Orion is luck based as it is already but hitting him with a solar flare is not that hard if you are lucky. Bring him down as low as possible and then just keep firing at the sun instead of him. The suns flares needs to kill him. make sure to avoid the legs and icicles.
One of the main mechanics of this boss fight is Orion will encase himself in ice armor. He will also periodically spawn solar flares. In order to break the ice armor, you must shoot the solar flares at the right angle so that fireballs hit him, breaking the armor and giving you a chance to cause damage. You must make sure the final blow is from a fireball. So once he is at low health, try ricocheting fireballs to hit him and defeat him.
This is a one of the more difficult achievement since the level requires you to move a lot and hit the right angles so take your time and try to predict his movements to be at the right place in the right time.
