Which wins: Grease of Spider Climb?

[Croaker]

This came up in a gaming session last night: A wizard was hanging from the ceiling via Spider Climb, well protected by Shield and Mage Armor,and our sorcerer decided to use Grease to get her down to where we could reach her. How would this work? Would the sticky feet from Spider Climb ignore the Grease? Only on a successful save? Or would Grease always cause a fall?

On a similar note, any ideas on circumstance penalties to resist being Tripped or Bull Rushed while standing on a patch of Grease? Circumstance penalties to the opposed attack roll when resisting a Disarm attempt with a Greased weapon?

Grease wins.

I base this on the Slippers of Spider Climbing wonderous item which says:

Extremely slippery surfaces-icy, oiled, or greased surfaces-make these slippers useless.

Since the creator uses Spider Climbing to craft the item, it doesn't seem too far a stretch that the spell would have the same difficulty.

Thanks for the info. I hadn't thought to look at the magic item list for clarifications on the spells that go into making them.
