If a LoF goes through Nimbus plus as well as a saturation zone, do you get -2 burst? Do they stack? The wiki says that visibility mods for low/poor visibility zones dont stack but nothing on saturation zones.
Nimbus is a Low or Poor Visibility Zone (that can't be seen through with MSV) and a Saturation Zone, all of which are visibility MODs. No they don't stack and you only get -1 Burst as can be seen in the copy-pasted rule found below. EDIT: Saturation isn't a visibility MOD, but what you're asking is "do two Saturation Zones stack?" I would say no on the simply fact that it's the same MOD. http://infinitythewiki.com/en/Special_Terrain_Rules#Visibility_Conditions IMPORTANT! Visibility MODs never stack with other Visibility MODs. If an area would be affected by two or more Visibility Zones of whatever type, apply only the most obscuring. For example, if a Low Visibility Zone (-3 MOD) coincides with a Poor Visibility Zone (-6 MOD), treat that area as a Poor Visibility Zone. If two Poor Visibility Zones coincide, apply only one single -6 MOD.
