Armor Check Penalty question

[Lojaan]

Hey guys, do any of you know if armor & shield check penalty is cumulative? Or do you use the highest value?

So would someone in plate mail (-2) using a heavy shield (-2) have a total check penalty of -2 or -4?


I can't find this in the PHB.

Thanks!

I am certain it is cumulative, although there is not specific text explaining this about armor check.

Refer to the text in PHB, page 275 (bottom right) - penalties add together, unless they are from the same power.
