5th:True Seeing(?), Schism(?)
6th:Overland Flight
7th:Pers. Mind Blank(?)
8th:True Metabolism(??)
About the power choices:
[SPOILER]Crystal shard/Swarm of Crystals sub for the knife barrages. Force Screen is pretty much Sakuya's blocking animation from SWR.
Def. Precogn. & Time hop are filler, though the hop is at least time-related.
Phys. Acc. is an obvious one.
Dimension Door is for SWR 22C. Also good for transporting heavy object above unsuspecting victims during time stop, if only for the meme.
True Seeing & Personal Mindblank are sorta mandatory at high lvls, right?
Schism is handy, if hard to justify for her.
Overland Flight, duh.
True Metabolism is sorta filler, mostly to have a use for 14 rounds of time stopping. Can be partially justified with accelerated natural healing, though the regeneration effect doesn't go well with that excuse.

There are dissapointingly few powers that deal with time to grab, so i had to make do with these.
Didn't include items and went with a 25 pt-buy. Potentially playable 1-20 i'd say, at least in low-op games. Can stop time for 14 rounds on lvl 20 (3pp(Phys.Acc.) + 6pp(Aug. Temp.Acc.) + 6X2pp (Augment dur.) + 2pp(Extend power)) using wild surge. More than 7 rounds aren't really needed, though.
On those six rounds, a sequence of:
7.) Schism/Focus/Physical Acc.
6.)diddly-squat(main), focus(schism)
5.) Aug.(+15d4) Delayed Swarm of Crystals/Focus/A.D.S.o.C.(main), Aug.(+9d
4) Delayed Swarm of Crystals(schism)
4.) Focus(main)/A.D.S.o.C.(main)/Focus(main), Focus(Schism)
3.) repeat of 5.
2.) repeat of 4.
1.) repeat of 5.
0.) open fire .
(3+1+3+1+3) => 8x18d4 + 3x14d4 = 465 slashing damage, no save/AC/SR. Good enough to take down most things in the MM. Bit of a one-trick pony sadly.
Also, the feats are a bit ... uninspired. All the necessary stuff is there but it could use some work. I mean, skill focus ? Also has room for flaws for adding a feat combo, maybe something based on Robilar's gambit, the skirmish damage & AoO from moving? Picking up Hustle
w. Exp. Knowledge would allow two extra Swarms for a bit more damage, though pp/d starts to become an issue.
One option would be using Delayed Telekinetic Thrust + Quickdraw during stopped time, drawing daggers as free actions and dropping them in-air to suspend them, with a Delayed Tel. Thrust to launch them when time resumes. Though what happens to items you let go of during time-stop effects is a bit of a mystery. Also, the Tel. thrust method is ridiculously weak to DR of any sort.
