She sits forward, speaking briskly and radiating authority. "In that case, the risk is that the cult does have high circle casters. Mostly clerics, but they have no doubt recruited from the Hall of Whispers, I'd expect some wizardry. Clerics are best with time to prepare, so we want to waste that time. The warehouse blueprint claims it has several rooms, I assume? Worst case, they have zombies and skeletons to slow us down and make noise, then they buff while we're stopped. Blessing of the Watch is our only time limit, so we want to make them waste their buff time. If they come out, they're leaving the safety of their Explosive Runes, or their Symbols if they could find the components, or their shrine-boosted Desecrates, or whatever they have set up. We want that. Shake down a room, make sure it's nice and obvious to anyone in the next that we're on our way in, then wait ten minutes, roll a few dice for an extra ten or so. If they buff up when they hear us coming, we can wait out the times. If they wait, they have to guess our dice. If they buff and come through the door when we don't enter, we get them out of their prepared terrain."
Then she fades back, slumping a bit in her chair, leaning a little awkwardly as she nods to the captain. "...or we go with the standard guard protocol, whatever that is. I have at least six spells left for the day, which can be Color Spray or Ray of Enfeeblement, or they can be a new spell I got this morning. I'd guess it's Silent Image. If I say I'm using my new spell, that means it's an illusion, expect it to be fake and look closely. I'll try for a thick fog, something which could be Obscuring Mist or Fog Cloud, so with luck the Urgathoans won't all see through it."
