Thorn Chakram

It does not snap straight back the way most boomerangs do. It flies out, ricochets off whatever it meets, and only turns around once it has slowed down. The moment it starts decelerating it changes character: unlimited piercing, and it passes through solid blocks. So the damage is not in the throw, it is in the long slow tail at the far end of the arc, where the chakram drifts through a group hitting everything repeatedly and can even reach something standing behind a wall.

Aim so the end of the flight lands on the enemy rather than the start of it. Melee speed bonuses stretch the reach because they raise the throw velocity, and liquids shorten it for the same reason, so it gets noticeably worse in flooded caves. The poison it applies about half the time compounds well over those slow multi hit passes, since each pass can reapply it.

It comes home fast, but it will not chase you forever. Get too far away from it and it vanishes, and it expires on its own after about a minute if it never finds its way back. That only bites if you throw it and immediately hook across the map.

Godly and Demonic are equally good here and both beat everything else. Take whichever one reforging gives you first and stop paying.

A real chakram is a sharpened metal ring thrown by warriors in India. It did not come back to the thrower and it certainly did not bounce. For a long stretch of the mobile version, this was also the sprite that spun on screen while the game saved.
