Grease and standing up

[EdwinM]

Quote:

Each creature standing on the greasy surface must succeed at a Reflex save or an Acrobatics check against your spell DC or fall prone. Creatures using an action to move onto the greasy surface during the spell’s duration must attempt either a Reflex save or an Acrobatics check to Balance. A creature that Steps or Crawls doesn’t have to attempt a check or save.

Does a creature standing up in grease need to make a saving throw?

a) yes - standing up is a move action and the creature is in grease

b) no - a creature standing up does not move onto the surface since it's already there

c) other

I say it doesn't need to.
But once he's standing, it goes down to the first sentence

"Each creature standing on the greasy surface must succeed at a Reflex save or an Acrobatics check against your spell DC or fall prone"

So the character fail the reflex/acrobatics DC, falls down, stand up and when standing on the greasy surface one again attemps another reflex/acrobatics check.

Doesn't the first sentence only apply to when the spell is cast? The wording of Grease's description isn't very precise at all, but that would make one hell of a 1st level spell.

The part of Each Creature standing is only valid when you cast. After that you can step or crawl without danger. This would imply you can also stand up and not move in any other way.

Otherwise you would step and still have to make a reflex save as you would still stand. It also means once you have succeeded on a reflex save you don't have to do another one - unless you try to move away faster as stepping away.

Edit: Otherwise you end up in an endless loop.
1) you are standing - make a reflex save
2) you succeed the reflex save - so you don't fall prone
3) you are standing - go back to 1)

You may be righe there.

"Creatures using an action to move onto the greasy surface"

might be not clear ( english is not my native language, so I pass on this ).

I just considered it's 4 squares ( at best, since the description says 4 contiguous 5-foot squares), and any creature would have been able to crawl out of the grease with a single action ( then stand up without consequences ) because whatever the square they are into, 5 feet crawl speed would be enough.

@Thod: I just considered to ST the first time you "stand" on the grease, since stand up is a move action. But the loop with kip up would have been fun to see.

Otherwise given a 4 square greasy surface, why would the creature step or stride onto the greasy ground? They'll be always steping/striding on the clean ground.
