When you have nothing to do . Ever . <| sep |> Nevertheless are all NPCs are built with 15 pb . The Encounters are designed for 4 PCs with 15 pb . The entire adventure path ROTR is based on the wrong 15 pb . So if you give the heroes the correct 20 pb you break the balance ! Because it was written with the assumption of 15 pb . You get my Point ? PFS which is something newer than ROTR and other old AP uses the 20 pb . You should take 20 pb as a base for new products and 15 pb for the old ones . <| sep |> The base is the same but the device itself is different <| sep |> I run both . It ' s 6 cards that literally always help . I run a dragostapelia in case I have no other way of ditching chain . But rat is irreplacable . 2 lunalights from 1 card is too good
