How can Altitude and Humidity affect an Angel

[Sbfn]

Hello All

I would like to know how can humidity and altitude affect the perfomance on Angels and A.I.Rs

Thanks

altitude really shouldn't matter. That's just the air pressure around you which will be lower. Even though you live in Brazil the altitude may be lower or higher than in the US but it isn't big enough to make much of a difference at all.
