Iria takes a calming moment, opening her wings and flourishing her chain. She then leaps straight up into the air and coasts gently gliding down.
Spoiler: Actions
In order:

(1d20+24)[41] Leap up 8ft

Ending in square D17 3 feet up
Spoiler: EDIT* with question: ~Question widthdrawn~
So- the chart in the PH appears to go +4DC per foot, using this logic I can be 10ft up though the chart only goes to 8ft [implied pattern, no obvious line I can see suggesting further is impossible- will check EHL in a moment]
So I'm a derp and missed that the chart below despite being all about reach is also mentioning the limiter for the height of a jump for a medium creature... bleh- kinda makes jumping up suck but whatever...
