GawainBS: Thanks for the reply. Can you explain this part, please? "Tongi with piercing grace"
Also, why would Scimitar benefit me? It's not a dex-based weapon, is it? I'm mainly looking at the DEX based weapons. (i.e. usable with Finesse.)
I definitely want to play a Magus, without too many dips.
Now, if dipping into Monk won't net any substantial benefits, is it still worthwhile to go Sword Saint over Regular Magus?
slashing/fencing grace are feats that allow you to count any 1h that does slashing or piercing as a finesse weapon. it also allows you to add you dex mod to damage as long as you have 2nd hand empty, which magus always does.
from 1h weapons that do slash or pierce clear winners are tongi and scimitar. good tongi are nowhere to be found till the master brings you one. so there's that - it might be a bit of a suffer till then. sabers are readily available though the game and are generally geared towards magus.
a word about scions in general and sub-classes:
base class: is just bad. no AC, no Damage, no nothing.
sword saint: some ac from int, gets to do a bit more damage when he gets to 13 with prescient strike
draconic bloodline Scion: Dex: THE tank among the bunch. about 10 more AC, than pure saint. kinda lacks melee damage boosters, but hey, he still has touch spells and arcane weapon. that has to count for something. also has pretty decent AOE spells.
Str: about the same AC as saint, but actually gets power attack and 1.5xStr damage and with it a good use for arcane accuracy. The damage dealer of the bunch. his only AOE to speak of is dragon's breath(from DD), but it should be enough in most cases.
in general, scion is geared towards front-line tanking and does lack burst damage classes with sneak attacks or good boosts can do, so don't expect any wins in damage olympics.
multi-classing for saints:
monk is good. question is when. another question is if you want to go hard into spells. if we could get to 20 saint/duelist would actually be pretty good with saint13/duelist7, but this is not the case. 18 is possible, but it will pretty much offer you nothing until you reach it, so I'd pass.
what is left would be saint16/monk1/vivisectionist1(if you ever get to 18. it depends on how much mobs you'd grind on the map).
when we'd take monk would depend on the race. we have 3 options:
-Plumekith aasimar: best will save as you'd go for traditional monk then. meh ability and wings come late for the tempo.
-Musetouched aasimar: even worse saves, but it's cha, so you get to be the talker of the group. some find it important for PC. scaled fist monk. wings come late
-Halfling: +dex+cha+1size ac+1all saves+early cautious fighter. scaled fist as well.
halfling will totally want to go monk at 5 so she gets both crane style and cautious fighter at that level.
aasimars would probably go monk at 9 to get crane style and crane wing at the same time, taking dodge prior to that.
pure Class saint:
it's ok. you do get some AC from maxed int, so monk is not totally vital. you will also miss out on LG monk robes, but censor robes give 2 dodge AC, so it's not that painful. A lot fairer to the game, than it deserves, if you ask me, but if you want to play more "balanced" character, that will actually get hit - it will do.
upd. fixed some typos.
