I have the following 1000pt army for an upcomming tornament:

Marneus Calagar

4 x Lvl 2 Librarians with Terminator Armour, Force Staves and Storm Shields

5 x Thunder Hammer Storm Shield Terminators

1000pts One big Librarius Conclave

The Questions is what powers to have on the librarians (without just taking Telepathy on all of them to get invisible) I was thinking:

Telepathy
Biomancy
Librarius
Geokinesis

What do you think?
