Shyra slides down the rope quickly, then activates the springs in her shoes - one of her favourite inventions! - to jump into position to flank one of the rats with Hamza, and she stabs it as deftly as she can manage.
"How." stab
"did." parry a claw
"you." step away
"get-so-big?"
As the blow finds purchase, Hamza is briefly limned in white light that seems to ease her injuries.
Shyra grins at her and waves a kukri in salute before returning to her target.
Spoiler: OOCIf flanking is not possible without her getting an AoO, subtract 2 from her attack roll and the 1d6 SA from the damage.
But if she needed she can use Crane Step or Leaping Dragon to reposition as a swift action, so it should be possible.
Move: climb down
Swift: Leaping Dragon (roll OOC: 35), she moves 35ft.
Standard: Enduring Crane Strike
Attack (1d20+6)[18]
Damage (2d6+4)[9]* Sneak Attack (1d6)[4]
Healing for Hamza if she hits (1d6+2)[6]
* 1d6 comes from her stance
