Like the equivalent Animate Dead spell, this invocation leaves much to be desired. The summoned undead is not really better then a level 1 fighter. Even the skeleton warrior (summoned at level 10+) has poor equipment, low hit points and statistics; it is a level 3 Undead, with single attack at +2 to hit, which is unlikely to hit many creatures at level 10.
See the Animate Dead page for more details.
As of 7/29/2010 with OC and MoTB installed and the current patches. The summons are a bit improved over the description. You should have a Skeleton Warrior with 8 levels of Warlock. Haven't tested how is scales from there, however. The minion is pretty good for a level 8 Caster and you get an unlimited supply.
Also, this is not a direct attack. It, therefore, does not break the invisibility of Walk Unseen.
