Here is the suggestion again, word for word, for referance
quote:
"Abandon your liquid terrain henceforth! No longer shall you walk upon the boiling acid!"
"Henceforth" and "No Longe"r were included to ensure that my suggestion was not just a one off deal but something that lasted for as long as possible and to ensure you wouldn't try to return to the water once you were off of it.
While you may be able to get around the second part of the suggestion with semantics and word play, the first part is very clear.
"Henceforth (From this point onward), you shall abandon (discontinue, stop) using the liquid as terrain (ground, land)."
Moving from one pillar to the next is using the liquid as terrain. Which is not allowed via the first part of the suggestion.
More over, "upon" does not necessarily mean "on". In fact a synonym of upon is "above" and a definition of upon is "in or into complete or approximate contact with, as an attacker or an important or pressing occasion:"
See, "upon" can mean "approximately on" and water walk only allows for at most two inches of distance which i'd say is a pretty approximate contact.
but if you're insistent that upon and on are the same word, let's examine the spell description for water walk, which is what i'm assuming you're using to traverse the acid.
quote:
The transmuted creatures can tread on any liquid as if it were firm ground. Mud, oil, snow, quicksand, running water, ice, and even lava can be traversed easily, since the subjects’ feet hover an inch or two above the surface. Creatures crossing molten lava still take damage from the heat because they are near it. The subjects can walk, run, charge, or otherwise move across the surface as if it were normal ground.
If the spell is cast underwater (or while the subjects are partially or wholly submerged in whatever liquid they are in), the subjects are borne toward the surface at 60 feet per round until they can stand on it.
the spell description clearly says that the effected target walks "on" the liquid. Never mind the fact that your feet hover above the liquid, the spell treats you as walking on it very plainly with the boon that you avoid the ill effects of doing so such as slipping, moving half your speed, sinking into the liquid, ect.
Now once again, i'm all for letting the GM settle this, but do keep in mind that you can't go back to using the liquid as a terrain unless i knock you down again. I'm certain that the first part is as clear as it can possibly be with no room for interpretation beyond what is expressly stated.
