Okay, Tim.  It's almost H-hour.  Let's do this.

Tim thinks for a second, closes his eyes and just breathes.
Backlash zero, check.
Tim runs his fingers along his load-bearing equipment, lovingly caressing the seams.  Gentle tugging, then hauling on them with his natural strength.  All good.
Vest, check.  
Tim carefully pulls the armored plates out of his plate carrier.  They're heavier than standard, since he can deal with the extra weight.  Custom-built and expensive, but how much would YOU pay for a working kidney?
Plates good, check.
Tim draws his wristbreaker pistol and gives it a once-over.  Pulls back the slide, checks the receiver.  No time for a full disassembly and he did that last night ALREADY, but it's on the checklist, so it gets checked.  It turns out that if you are willing to trade off recoil and ergonomics, you can launch larger chunks of lead in a pistol form factor.  And if you can choose to make yourself stronger when you're firing, recoil and ergonomics don't matter that much.
Wristbreaker good, check.
Next, his silenced pistol.  The silencing is more done out of courtesy for any espers in the dungeon.  It's pessimistically assumed that if you don't have a stealth power, you can't reliably sneak in a dungeon.  It's smaller and "only" loads rifle-grade 5.56mm rounds, though the magazines are significantly larger and heavier than standard-issue.
Pistol good, check.
Ammo pouches on his thighs.  All magazines loaded?  All in good condition?  Excellent.
Ammo, check.
With some trepidation, Tim moves onto the next item.  Two demolition charges?  Still sealed?  Detonators in a separate pouch?
Explosives, check.
Toolkit?  Wirecutters, a baby sledge, a chisel, spray paint(two colors, orange and teal, both eye-searingly fluorescent), some other odds and ends this narration is tool small to contain.
Everything where it should be, check.
First aid kit?  Tim pores over the various supplies.  He won't bother with sutures, but eyepatches and bandages and a tourniquet kit and various painkillers are available.  And two pre-loaded syringes to make someone very sleepy for extraction.
Medbag, check.
Went over the clothes before this.
Clothes, check.
Stretch?  Tim will do a quick jog around the room, then start in on the Baduajin.  Slowly, smoothly.  Not putting his whole effort into it.  

"You ready, sir?"

Okay.  It's M-minute.  Let's do this.
