Welcome to Librarium Online!
what do you find to be the most useful and cost efficient power. im not sure if i should get just one or two. i have about 80pt left to beef up my librarian, but keep in mind, i want to use some of it to beef up my chaplain as well (so i cant use all of it on the Librarain).
That is not dead which may eternal lie,
for in strange aeons even death may die.
Might of Heroes is pretty versatile and if you replace Storm of the Emperors wrath, pretty cost efficient too. You can use it to beef up other individuals in the squad if say you going up against a dread and have a guy with a PF, or you can simply use it to make him a beast with up to 9 attacks.

Well as to powers:
Fury of the Ancients would be my first suggestion: table-edge range, multiple unit hits, no LOS required, works against all armies (unlike Fear), pinning tests (though this doesn't work against all armies) and rediculously cheap. My DW Libby never leaves home without it.
Might would be my second choice: works against everything (providing Libby, or his attahced/command squad are in cc of course) and is easy to use.
Fear would be my third choice: works well on a drop podding Libby with command squad but only against some armies- Nids and Chaos are largely immune. IG and Eldar and Tau are primary targets for this power, all the others can ride the storm if they are lucky.
Veil well its expensive, but does work well in ALL phases of the game so a lot can be done with it.
Storm, Vortex I don't use. The first is too limited, the second too expensive and can be liable to end up in sucking your own guys into the warp!
Hope this helps

I usually take fury and veil because veil keeps ur libby alive and fury is very cost effective and almost always makes up its points. Those 2 powers make a well balanced librarian
