Advice for building a debuff-focused magus going Evangelist PrC

[keerawa]

I'm interested in creating a magus who is a devotee of Sarenrae and focuses on debuffs rather than nova damage. She'll be taking the Evangelist prestige class at level 6.

I've read Frodo's Kensai guide, and am very interested in his 'Frostbite' build.

I'd like to use the 'Blade of Mercy' trait to do non-lethal damage, and then take the Enforcer feat to allow for free Intimidate checks to make enemies shaken. At higher level I'd be using a cruel scimitar to make them sickened as well, and Rimed Frostbites to make them fatigued and entangled.

Here are a few points I'd like advice on:

1) I've heard that Magical Lineage is spectacular for magi, and I can see why, but it seems like I'll be making a lot of concentration checks for defensive casting. Would Focused Mind be a good choice, instead?

2) I'm leaning towards kensai. The benefits are tasty, but I'm wondering, for people who have played both, whether it or a 'vanilla' magus would be a better choice for this build.

3) I'm considering dipping a level of Dawnflower Dervish, at first level. That would give me a free Dervish Dancer feat at level one, without the Weapon Finesse prerequisite. I'd also gain a bit of spell-casting ability and some more class abilities. The battle dance would be a nice bonus for a few rounds a day.

The disadvantage is that this will frop me two levels behind the BAB and spell progression curves of a full kensai.

The build would look something like this:

Str: 10
Dex: 17
Con: 12
Wis: 10
Int: 16
Wis: 8
Cha: 12

Level 1: Dawnflower Dervish Bard
Levels 2-5: Magus (possibly kensai)
Level 6: Evangelist
Levels 7-12: Evangelist with Magus

Traits
Blade of Mercy (Faith)
Focused Mind (Magic) or Magical Lineage (Magic)
Anatomist(Combat)
Bruising Intellect (Social) or Maestro of the Society (Social)

Feats:
1: Dervish Dancer (bonus), Enforcer, Additional Traits (human)
2: WF:scimitar (bonus)
3: Deific Obedience
5: Rime
7: Toughness, Intensify(bonus)
9: Extra Arcana
11: Lunge

Any suggestions?

You don't need blade of mercy if you're going to specialize in frostbite
Magical leniage is significantly more important than focused mind

Very much past tense (didn't need) Lord Foul. keerawa's thread has been raised from three and a half years of peaceful rest in the grave.

I somehow missed that as I was posting while half asleep heh
