Effective Communion?

[Cainehill]

So try having a plan for how to use it. Think of all those battlefield spells that normally, the only way you could cast it is with your pretender (or unique summons) because it requires 5, 6, 7 levels in a path : Armies of Gold / Lead, Bone Grinding, Mists of Deceptions, Soul Drain, Master Enslave, Undead Mastery, etc. (Note that some of these are easier to cast with CB 5.2, other spells are now harder.)

Going from being unable to cast a powerful spell to being able to cast it is a pretty effective use of Communion. Likewise, being able to cast more powerful offensive magics, at a lower fatigue cost - especially handy with spells whose damage and AoE both go up with magic power.
