what is the best 'major magic' spell choice for knifemaster rogue?

[asthyril]

So a 6th level elven rogue choosing a 1st level wizard spell for the major magic rogue talent, which would be the best spell to choose? i know utility is usually best but if there is an offensive spell you might think of, my rogue has a 16 int so the saving throw wouldn't be horrible.

my ideas have been:
-shield for a bonus to AC
-unseen servant because it lasts so long and is like super mage hand for 6 hours, and can set off traps
-anticipate peril for an extra +5 initiative (i don't consider that one that great now)
-charm person for out of combat bluffing
-floating disc for hauling treasure, but primarily for moving other people around using my move action (if it works that way, im still not sure)
-vanish for obvious reasons
-animate rope if i am ever tied up i can easily get out
-reduce person since all my combat stats rely on dex, it's all win

i know some of these are better than others, but anyone have any ideas or spells i haven't thought of?

floating disk has all sorts of awesome uses.

True strike, Expeditious retreat, icicle dagger, Feather fall, Chill touch, liberating command, Grease. All are descent options. Sorta depends on what you expect to happen in the campaign, fighting style etc.

vanish is neat.

I like Vanish the best. It gets you out of some tight spots, and the opponent doesn't get a saving throw; it even lets you get sneak attack.

Charm person could be good if you dumped charisma, but for a lot of the others you could probably just get a wand and ask one of the casters to zap you.

I think vanish becomes pointless very quickly. At some point many enemies will see through your invisibility until then a ring of invisibility will do the trick.

I think that 6 years after the OP asked for ideas for their 6th level character is a little too late for suggestions to be helpful.
