What spells to use?
Charm person is the first one you need. 1st level spell.
When you can cast third levels, you want
suggestion so you can charm non-humanoids.
Fourth level spell charm monster is one I would switch out for suggestion since your DCs will be pretty high.
Suggestion: short duration,
Charm monster can be much longer or shorter depending on the save of the monster.
5th level spell dominate person is an awesome spell and you can drop charm person. Although you could keep charm person, I find dominate person will last forever.
Mass charms..... Mass suggestion, symbol of persuasion, mass charm monster- This will depend on your strategies. These will charm, or try to charm, in an area with no selective option, what is there will try to be charmed. Persuasion does charm things the other spells do not.
Mass suggestion- three monsters at most, short duration, dangerous as all pop at same time.
Symbol persusion- seemingly unlimited mobs til it goes away, can be dangerous as all pop at same time.
Mass Charm Monster- unknown for sure as of yet.
I personally only use Dominate person and charm monster (once i am able to cast that level spell). I dislike mass charming and having the two spells usually lets me cast as often as I need without a wait for cooldown (the old 1-2).
Yes, you can still take fire/cold enhancements, get superior lore items, get the best crit chances, get the best multiplier, but you may want to just get maximize and may not be able to get empower to go with it. So, yes virginia, you can still nuke santa claus.
