What's the thought on Spell Penetration and Greater Spell Pen vs Spell Focus and Gr Spell Focus for pure clerics specced for healing and casting?
My cleric is currently level 15 and I have Toughness, Emp Healing, Extend, Maximize, Heighten, Spell Pen, and Gr Spell Pen. I plan on taking Quicken at level 18.
But I'm wondering if I should swap out Spell Pen and Greater for Spell Focus in either Enchantment, Necro, or Evocation. I tend to use a mix of spells (Greater Command, Slay Living, Blade Barrier, Destruction, etc) so I'm not sure which Spell Focus would be best.
Also, what about taking Spell Penetration and Spell Focus instead of 2 feats in one chain?
