Move: turn around to face the stairs
Simple: Ready Grenade Launcher This will put the launcher in her left hand and the blade in her right.
Simple: Aim Grenade Launcher
Free: Shout at guards, if they come into my line of sight before the next turn. If not, I'll use the action to send a message to the team.
If A- "You stand in defense of demons! Lucifer, the father of lies has claimed this place for his minions. Leave here now and you may still escape their fate!"
She doesn't have the intimidate skill, but she DOES have a grenade launcher pointed at them. They don't know it's loaded with pepper nades.
If B- <<@Team [Sister Rebecca] Hostiles moving on my position. Engage?>>
Oh, also, can we assume Becca is streaming her biomonitor info to the rest of the team? I meant to mention it before we got outta the van.
Also, a pepper nade obviously doesn't make as much noise as an actual exposive, but I betcha it's still kinda loud. Compared to the music in this place, how loud would it actually be?
Becca has no way of knowing this, so feel free to not answer.
EDIT: OH WAIT! Is it too late to change my action?
I just thought of something way more effective!
