Ok the first one came up in a game and just want to confirm that it was legit:
I am defending away from an attacking horde that takes my province. 4 on their side 3 on mine. At my battle I play 2x reprisal on my 4 force unit making it 6 force. On my first reprisal attack I play Advance warning and lower the province strength by 6. On my second I assign the same unit to the same province. I take the province.
My opponent really wants to confirm if that was totaly legal. (He really wants it to be)
I guess the real quesiton is what is the duration of the lowered province strenght for advance warning.

The default duration for any effect without another one stated is "end of turn". So, enjoy that lowered PS through both Reprisal attacks!
