So I finally have decided to venture into the horrible Prestige realm of PFRPG, and need a bit of help. Mostly in the choosing of path abilities and such to fill in the holes my prestige will leave me with. A few things to note, My DM is letting my MT levels stack with my levels in cleric and wizard for determining domain, school, and caster level, and is also letting me go to Lvl 14 Mystic Theurge.
Currently My Lvl 1 Stats are looking (25 Point Buy, Aasimar [Replaced Spell-Like Ability with +2 Int)
9 - Str
10 - Dex
12 - Con
19 - Int
19 - Wis
10 - Cha
Now the current plan is first 3 Levels Cleric because I don't want to die in the first dungeon, and then the problem comes when I drop the point in Int and cross over at 4, but apparently the campaign goes nuts at that level. Mostly I'm trying to survive to start making items to buff like crazy. For Mythic I'm looking at going Archmage, going Dual Path Hierophant. Advice?
Considering your DM is handling you with kid gloves I would try to get the Improved Caster Level Feat at first level, or taking Practiced Spellcaster twice. My advice is to lead with one class then follow up with the other till 6th level. Feats that provide a static bonus like toughness, Improved Initiative, or Warrior Priest are more your friend than most feats, but item creation is a good racket.
Having a familiar is generally a feat hole but since your gm is insisting on spoiling you you might be able to have one anyway, otherwise I recommend a bonded object, either a dagger or a ring.
My advice is stay in the rear and cover your party with buffs, it makes the Martials feel like rockstars and I think its pretty fun to do usually. Palm a fun looking circumstantial spell and have fun with cantrips because what you have more than anything else is variety, not power or direct utility.
Wow... that's a pretty sweet hook up you got there. It's almost a gestalt character, sheesh. MTs usually have a role as a buff bot, but if you're going to be able to keep your caster level for both classes current, you'll be able to reliably cast offensive spells. One thing I'd recommend is to pick either arcane or divine to focus on, for purposes of save DCs, and focus on buffing that stat. Another thing I'd recommend is seeing if your GM will let you join a spellcasting guild (from Inner Sea Magic). For 200gp every few months you eventually get +1 to caster level in one class and +3 in another (and unlike other caster level buffs you also get access to spells and spells known with this). This campaign is crazy on evil outsiders right? I might suggest for your wizard school going Evocation (admixture school) to get around the various elemental immunities of evil outsiders. You're definitely going to want Spell Penetration and Greater Spell Penetration too. If your GM will let you, consider crafting feats, too. At least Wondrous Item. Going cleric 3 first is a solid plan, having some armor to help for the first few levels can be a big deal. Definitely try to pick up the Travel domain... since your MT levels are going to stack for domain powers, that's pretty freaking cool. Once you hit level 4 you trade in your armor for mage armor (or ASF chance) and you're well on your way.
Why are you giving up the spell like ability? Their are several varieties of Aasimar that have a 2nd level SLA. This allows you to go 3/1 cleric wizard then go into theurge thanks to the latest FAQ or even better instead of wizard take 1 level in empyrail sor. so you're casting stat is the same for both. It gets you into the class 2 levels earlier. Tielfling does the same thing
But this will leave me with less arcane spellcasting variety. And I was thinking of going a little more variety than straight optimization (although it hurts my insides). Also then my arcane spellcasting will always be 2 levels behind that of my divine. Thank you though :). As for the inner sea magic, Idk if i can keep getting away with things... Anyone with ideas for mythic?
It sounds like you are getting a pretty "optimized" version of the MT as it is. All you're giving up is channel progression, familiar progression, and wizard bonus feats. One thing you could consider is the Spell Focus (in place of Scribe Scroll if your GM will let you, since PFS allows that anyways he shouldn't have a problem with it) - Augment Summoning - Superior Summoning - Sacred Summoning - Summon Good Monster feat chain, if you like to summon critters and have a suitable alignment. I couldn't comment on the mythic stuff, I don't have the book (yet - it's supposed to arrive while I'm at dragon con this weekend) but once I have a chance to look it over I'll see what more I can add to this discussion.
