R2T22: Pim looks above to the commotion and nods with a knowing look on his face while drawing a card. He flattens against the ascending wall in order to reduce his profile as much as possible while he concentrates on a defensive strategy. First, he activates his defensive cards. However, they only begin to manifest their magical visual cues after a few seconds, so in the meanwhile, he attempts to protect himself fully from any incoming attacks. Unfortunately, while a pretty good climber on what is a ridiculously easy climb for him, Pim realizes that his attempts at defense would be for naught if actually attacked.
Spoiler: Climbing & Defense
Show
Unless you have a climb speed (you don't have spider climb cast on yourself right now), it doesn't matter what your skill-to-DC of the climb is ... you are "climbing." Which means you lose your DEX bonus to AC, and also means all dodge bonuses to AC are likewise lost. Total Defense provides a dodge bonus to AC.
During all this, Pim mentally communicates with the group ...

”I’ll help someone beefier than I to fly in just a moment, Torber, that likely means you?”

R2T19: The white-furred simian seems to notice something below and well to the side, hopping over the side and climbing down at breathtaking speed.

At a height of 30', Fronaldo is 10' above and below the next and most recent steps of the ziggurat (heights of 20' and 40'). Suddenly, a white-furred, four-armed simian appears over the next level of the ziggurat and climbs down almost like a spider (but with six limbs instead of eight). It is so fast, it got from wherever it was before down to a height total of 35' (right above Fronaldo) and still attacks him! It's great, multi-tusked maw snaps at him, biting at the little goblin's shoulder for 7. That is when Fronaldo that all of his agility is for naught when he is climbing!
Spoiler: Uncanny Dodge vs. Losing DEX to AC
Show
Most people assume that "losing DEX to AC" means that one is flat-footed, or vice-versa. This is not the case. You are not flat-footed when climbing (for which Fronaldo's Uncanny Dodge would apply). Rather, just like using Acrobatics to balance, you lose your DEX bonus to AC (which Uncanny Dodge does not protect against).

R2T18: Gelik, you understand the challenges involved with those that climb and how vulnerable they are against natural climbers. While the charau-ka are really good rock throwers, they're also punks. The big white, furry Bumble on the other hand, is on terrain that takes all of Fronaldo's combat brilliance and makes it useless ... meaning he is about to be in a bad way quickly. What do you do?
