MP: new NoooB Game, (Running)

I think you had your reverse communion wrong, basically, spells get casted in the way your mages appear in the tactic-setup screen, with the mage on top being the first one to cast etc.
One thing to note is that, after a communion master cast a spell, all slaves can no longer cast in this turn, if you want to use a reverse communion, the master always needs to be at the very bottom of that list.
So, if you wanted to setup a situation in which one (non communioned guy) casts the general +1Astral battlefield buff (Light of the northern Star), a communion master casts Power of the Spheres, and the rest of the communion fires away with +2 Astral boosted Soulslays, you were doing it wrong because your communion master was like, the 4 mystic if counting from the top. All of the communion members below him never cast a single spell in that battle. You could even see some trying to get into mellee.

If you have 4 mystics, and those mystics appear like this in the tactics screen:
Mystic A
Mystic B
Mystic C
Mystic D
remember to let the communion master be Mystic D, so that the other 3 Mystics still can cast spells, note that "target caster" buffs your master casts effect all communion slaves, and that he still gets the communion path bonus even if his slaves already cast soemthing. So, if you have a Mystic with earth somewhere down on the tactics screen, use him to cast "Communion Master, Power of the spheres, Summon Earthpower" the reinvigoration is very worth it.

I also wondered what your Oreiads were doing, their seduce is basically an assassination attempt that once in a green moon gets you a free commander, and an Oreiad can be scripted/equipped to be capable of dealing with Agarthan Orcales scripted to cast Blade Wind.

Other stuff you could have done:
-Layered castings of "Swarm". Agarthan boulders are quite capable of hurting other Agarthans, and Swarms are awesome for provoking friendly fires.
-Thunderstrike/Storm. Any A2 caster under power of the spheres, or even A1 casters under Storm/power of the Spheres can cast it. It does not care about MR, deals additional fatigue damage and is propably better than Soulslay for comparably High MR Agarthans.
-Penetration boosters: From memory, Acro can forge a number of penetration booster naturally. Those help a lot with Soul Slay/Paralyze etc.
