@Tec, wow! That makes up for some of Achak's performance at the yak club, I'd say. Glasses can be added to the load-out no problem. So, let's take these in order.
Sneaking: That's hella sneaky. If it ends up being combined with a Spirit's Concealment power, then that's just nasty. Nobody jumps out at him on the way over.
Perception: we'll drop dice from the end, so all 8 hits count for hearing/vision/scent. For hearing, this really shouldn't be possible, but since 4 hits can hear subvocal speech, I'd think that 8 would allow Achak to hear snippets from around the building and through the rain to the parking lot where the three goons are currently stationed. I'll post that below. For vision, the ladder looks sturdy, and nothing really appears amiss. Achak is fairly certain that he can squeeze by the camera's potential feed. For scent, there's probably too much competing stimulus to get a bead on anything useful. What he is certain of, is that nothing was so invisible that he couldn't see it but might have the potential to smell it nearby.
Magic Sense: a question arises: would Magic Sense pierce walls? I'm thinking no, but let me know if you feel otherwise. Achak senses the magic of a man by the front of the building, as well as Foci on him.
I'll need a jumping test to get to the ladder. Or, one can give the other a boost.
ETA: forgot to list the convo bits Achak is able to hear.
Voice One: ". . . is not pleased that she had to come down at all."
Voice Two: "Ms. Pachis shouldn't have to wait much longer. We've--"
Voice One: "That backups weren't ready . . . hours."
A brief pause.
Voice Three: "So, is it true?"
Voice One: "Yes. Whole team. Why the frag else would you be here?"
Voice Three: "We were just wondering,"
Voice Two: "Yeah, if, umm,"
Voice One: "Not necessary, I'm sure. 'Sides, you hoops can handle it, eh? Now quit . . . out there."
Another pause.
Voice Three: Whip's got . . . right up . . . hoop."
Voice Two: "Shut up."
