Hi, noob here, I have a friend telling me to always get spell penetration first and foremost because it's a larger benefit to the same thing, but they are worded so differently. It makes me think Spell Focus makes it tougher for enemies to make those saving throw drawbacks like 'damage is cut in half on a succesful reflex save' it would make the reflex save tougher on the mob, vs Spell Penetration making landing the spell in the first place easier on me.

Could someone explain the trade off to me a little better?
