The VOIDRUNNER'S CODEX is coming! Explore new worlds, fight oppressive empires, fend off fearsome aliens, and wield deadly psionics with this comprehensive boxed set expansion for 5E and A5E!
There's a lot of mentions of a "brittle star" and "ophiuroid" that are changed to "land star" for example, and some of the wording has been slightly tweaked.
That looks fine, except it has the 20 ft. ground and climb speed of the aquatic regular Giant Brittle Star instead of the Speed 30 ft., climb 30 ft., swim 20 ft. of a land star.
