They find a sneering merchant who offers, as though reluctantly, Belts of Physical Might and Belts of Physical Superiority. Pilar buys a +2/+2/+2 Belt of Physical Superiority just to feel even lighter and more graceful on her feet, and a +4STR/+4DEX Belt of Physical Might for when she wants to be even stronger and more graceful for a lesser time of endurance.
And a +6 Belt of Giant's Strength just in case she wants to show that off; and a +6 Belt of Mighty Constitution so that she can be tortured for longer; and a +6 Belt of Incredible Dexterity if only to complete the set.
Why shouldn't she? Ione has money and has threatened that if Pilar doesn't spend it Ione will probably just spend it on Good.
Pilar buys a Hat of Disguise. When she finds better at another shop, she buys a Greater Hat of Disguise; with hardly a twinge of horror for the money spent earlier, it's a sunk cost anyways.
