How would you rule this...
My PC has a weapon of warning. It's not exactly alert, but it negates surprise for the whole party.
Bad guy NPC scry us. They are about to teleport in and surprise us.
DM: OK, your all surprised as I teleport in and everyone is shooting you.
Me: Weapon of warning remember no surprise...
DM: Fine, roll initative.
initative 24(my cleric/paliden) 23 (Tie the PC Rogue and the NPC gunmen) 17 (PC Fighter) 12 (NPC wizard) 11 (PC Ranger) 9 (NPC with us demi god) 7 (PC fighter/rogue)
so my turn first "So what do I see"
DM "Nothing they can't teleport in until 12...
Me "OK, I cast Bless"
DM "You can't nothing happened!"
Me "Yes something did the weapon of warning alerted us"
DM "Fine waste your spell"
(lots of discussion and declairs of actions)
finally on 12 DM "My wizard saw you do all this prep she isn't teleporting in she's going to wait for your spell to run out"
