All the questions!
Jumping Kitty:
Given Rani's size and her ability to jump, if Marik direct her to hop on the Creeper's corpse and then use the momentum to jump on the other side of the room, would that be easy enough for her or would that require a check? If so, would that be Acrobatics, Athetics, Animal Handling?
If she's leaping across give me Atheltics
Gallons of Blood:
Also, is the cause of death of the creeper obvious if he's bleeding so much? I figure it's not foot bleeding?
The source is the creeper's back which it is currently lying on.
Blood spray like in an anime:
Perhaps a medicine check to see whether Filimena can tell cause of death from a distance? Dunno if you wanna set a higher DC or if I should just roll with disadvantage, so rolled 2 dice anyway, 11 and 12. Guessing not enough in any case.
Filimena is PRETTY sure it has something to do with the blood coming out from the creeper's back
Tiny Dancer:
Would Filimena’s halfling nimbleness help in this case? If she can move through spaces occupied by creatures larger than herself conceivably she could move through the shards of grass and eramic, assuming their footprint is the same as that of a creature larger than herself =P
I'll allow Acrobatics w/ Advantage.
