Bull Rush...on ice?

[Rerednaw]

By RAW what modifiers would an attacker and defender have on ice with a Bull Rush Maneuver?

As far as I can tell, ice is difficult terrain (2 squares) though not specifically listed *as* difficult terrain and a DC 10 Acrobatics check is needed to charge on it.

I have not found anything else and could use some help.

Thanks!

I haven't found anything specific to bull rush, but the section on Slick Ice in this Paizo blog post might be somewhat helpful.

The only other thing I've found is

Quote:

Ice

Characters walking on ice must spend 2 squares of movement to enter a square covered by ice, and the DC for Acrobatics checks increases by +5. Characters in prolonged contact with ice might run the risk of taking damage from severe cold.

which doesn't really answer your question. As far as I know, there are no RAW modifiers for a bull rush while on ice. The GM, of course, is free (and encouraged) to apply situational modifiers or even situational skill checks if she feels it pertinent to dealing with the terrain.

if both the defender and attacker are on the ice, wouldn't the same modifier apply to both and therefore cancel each other out? the defender lacks traction on ice but so does the bull rusher.

Maybe, but if it applies only to CMB (or only to CMD) then they wouldn't cancel so much as make both characters equally inept at (or weak against) bull rush attempts.
