(Unfair) Domain Zealot or Elemental Barrage?

[gmwaddington]

I'm nearing Threshold, and I'm wondering what to take for my Rank 10 Mythic Ability. I'm trying to decide between Domain Zealot and Elemental Barrage (which I'm not very familiar with). I can cast Geniekind, and deal sonic damage with the Scimitar of Wind.

My character is a Halfling Trickster Divine Hound Hunter.

Stats (unbuffed)
Str 8
Dex 34
Con 21
Int 21
Wis 16
Cha 10

Available Weapons:
Finnean: +5 Brilliant Energy Scimitar
Dawnflower's Kiss: +6 Holy Scimitar (hopefully the bonus from arcana 1 will stick)
Scimitar of Wind: +2 (boosted to +5) Keen Thundering Scimitar

Trickster Mythic Tricks:
Arcana 1
Nature 1
Religion 2 (Community, Luck domains)
Perception 2
Trickery 1
World 2
Use Magic Device 3 (wizard spellbook)

Mythic Abilities:
Ever Ready
Enduring Spells
Enduring Spells (Greater)
Last Stand
Mythic Beast
Inspirational Leader

I can cast Transformation to increase my BAB to 20, however that prevents casting any more spells. I generally memorize 5 Quickened True Strikes.

Party:
I am playing on Unfair. I have been using a party of 5, but will probably need 6.

Arueshalae
Seelah
Mercenary Halfling Sylvan Sorcerer (buffing with Greater Enduring Spells, Greater Abundant Casting, Mythic Dog)
Daeran
Sosiel

Everyone has a pet (triceratops figurine for Arueshalae), so there will be 3 dogs, 1 horse, 1 wolf and 1 triceratops.

Note: I'm going for the Ascension Ending.

I'm looking for feedback from those with experience with Elemental Barrage about whether that's worth it.

You don't need zealot for community and luck.
EB is good with geniekind.
If you don't have bane of spirit ring, it's one of a few things that can deal decent damage to the final boss.
So you can pick it.

But personally I like having magic nullification ability on everyone (or at least most party members) for the final fight.
'cause ♥♥♥♥ her polar midnights and hellfire rays.

I usually have 24 hour Ice Body and Fiery Body spells on my MC and the Sorcerer merc, FWIW.

[Mindeveler]

IB and FB are nice but they won't block unholy damage from HFR or dexterity drain from polar ray or sacred damage from sunburst etc.
The final battle is much easier when the boss can no longer use the majority of spells.

I would do domain zealot for the luck power as swift action, if Aosiel dint already have it. I think it is more important to hit and make ur saves as the extra damage

Sosiel does already have Domain Zealot. My choices for him are Impossible Domain: Nobility or Last Stand. My MC could also take Impossible Domain: Nobility.
