[QUOTE="Cleon, post: 8561316, member: 57383"] As you like, Stealth +3 it is. Offhand I can't think of any damage vulnerabilities/resistances/immunities that seem appropriate and you don't have and in the current [B][URL='https://www.enworld.org/attachments/giantbrittlestar2-png.152623/']D&D Beyond Rough Draft[/URL][/B] so I'll cut that bit out of the Enworld Working Draft too. Updating the [B][URL='https://enworld.org/index.php?posts/8557938']Giant Brittle Star (Ophiuroid)[/URL][/B]. That just leaves senses. Apart from the default passive Perception 9 the Rough Draft has Blindsight 30 ft. and Tremorsense 30 ft. I guess we should consider (a) does it need both of those (i.e. would blindsight alone be OK?), (b) is the range long enough, and (c) should the blinsight have the "(blind beyond this radius)" proviso or not? Hmm, in order: [B](a) Tremorsense?[/B] This sense is mostly possessed by burrowing creatures, like a Purple Worm, although there are a few 5E monsters with it that don't have burrow speeds such as the Galeb Duhr. That said, some brittle stars burrow in the sediment and reach out their arms from the silt to capture food that's floating past so tremorsense isn't out of the question. Plus they're noted for having a keen sense of touch. Dang it, I can't decide but am leaning towards them just having Blindsight. [B](b) Range?[/B] This is trickier. Some Large "mundane" monsters have tremorsense 30 ft. like the Hunter Shark, while others like an Ochre Jelly have 60 ft. Perhaps it would help to consider how far it can feel with its arms? Which requires us knowing how long the are. Let's see, looking at some Brittle Star pictures online and scaling them up, I'd say a Brittle Star's arms average about six to eight times longer than the diameter of its disc-shaped body. So, if we say its body is 3 feet across the arms will be about 20 feet long. That suggests we should consider blindsight 60 ft., since it it had 30 ft. it could only sense things 10 feet beyond its tentacle tips. Which reminds me, since Brittle Stars have such long flexible arms they ought to have increased [B]Reach[/B] with their arm attacks. [B](c) Blind Beyond?[/B] Hmm, I'm not sure how effective their array of eyespots is at sensing creatures. I suspect it's fairly rudimentary, but it seems rather limiting to have the "(blind beyond this radius)" limitation. Perhaps we should give them some other restriction such as some kind of "rudimentary eyesight" trait. Perhaps they have Disadvantage on Wisdom (Perception) checks that rely on sight, and can only see shadowy outlines of objects and creatures? [/QUOTE]
