Magma is an Obsidian Discs midrange rated 5/5/0/2, intended for straight travel followed by a moderate fade. It fits approaches and midrange drives where a finish to the side is useful but a severe hook would get in the way.

Obsidian describes Magma as resisting turn under faster throws while remaining usable at lower throwing speeds.

The PDGA approved Magma on 19 July 2021 (21-79).

The Obsidian Discs Magma has only 3 reviews so far, so one opinion can swing the picture. That's why there's no star average yet.

Try Discs adds up reviews from six disc golf stores, so you see what players think across stores, not just at one shop. Reviews are great for spotting proven, popular discs. Take the details with a grain of salt, though: runs, plastics and skill level all change how a disc flies, so your experience may vary.
