Astral Lord Focus Reduces "Regeneration Penalty from Buffs" - Grants modification points to Astral Lord Aspect - Increases "Highest Spell level without Penalty"
Stamina Reduces "Regeneration Penalty from Buffs"
Concentration Reduces "Regeneration Penalty from Buffs"
Combat Discipline Increases damage a small amount, most effective if the "Sharp Blades" mod (1b) is chosen

Use Nether Allegiance along with Reflective Emanation and/or Rousing Command (both have mods to affect the whole party), as well as Augmenting Guidon.
Recommended mods: Sharp Blades, Spectral Shield, Elite Equipment. The more skelletons there are, the more they get in eachothers way and in the player's way. It may be better to have 2 skelletons that are spending more time hitting their targets with reinforced equipment and better armor than 4 skelletons that are either getting in eachother's way or dead because they don't have much defense.
If the player uses this buff, it is recommended to keep the level fairly high (without going over CA level without penalty) to ensure the skelletons can kill at a decent speed.

Pros

Units to do damage
Taking damage for you
Skeletons will continue to draw aggro even while 'dead'
If the skelletons "die" they do get back up again... but it takes awhile for them to resurrect.
They teleport to you if you get too far ahead

Cons

Roams around freely, usually not attacking the same unit you do
Too many skelletons can get in eachothers way, especially if you are using rallied souls at the same time.
Requires a high level for decent kill speed from skelletons.
Attracts unnecessary attention from other enemy units
Any enemy AoE or Reflect spell that causes damage to skeletons will also damage you even if invisible (using Shadow Veil)
They don't run very fast and it can take a few seconds for them to teleport to you and then find the enemy. No known way to increase their run speed.

Some research has been done [1] & [2] that shows the damage increase.

No modifications, no skills, naked, all stats between 25 and 35 (i.e. a nearly-new character).
