Callout amendment: Indicate tether side in P10S

[Flavescent]

In P10S, for the mechanics Dividing Wings 1 and 2, and in Pandaemoniac Web (the mechanic before Harrowing Hell), the callout should read "Point left/west tether away" or "Point right/east tether away", instead of just ""Point tether away". This is because the tethers are so narrow that it is difficult to see in combat which of the two poles players are tethered to, and going to the wrong side will kill the party.
