This sounds like really an issue, because you were a diona. species that are slow by standard, the tickrate isn't really a issue.
The tentacles can be easily avoided. you just move whenever it has red eyes(or prepare to atleast)
Bone breaking is a really edge case scenario. because you have around you alot of instaheals(or well get them atleast) which is basically a admin heal fixing your bones etc
so bone breaking isn't a instant death sentence but its to add to the difficulty of lavaland with baymed, another thing you can
(which i always do when fighting megafauna) is bringing stimpaks for some extra speed they just cost 50 points. yes they cause brain damage but better then dying right?
