Mythic Arcane Trickster?

[Eptaceros]

So basically, i'm playing a homebrew mythic campaign and decided to go arcane trickster. The party layout is currently myself, an oracle, wizard, zen archer monk, fighter. 25 point buy

Here's the current build (relatively):
Elf Rogue 3/Wizard 3/AT 1
STR 7
DEX 20
CON 15
WIS 12
INT 20
CHA 8

Feats:
1. Improved Initiative
2. Weapon Finesse (rogue talent)
3. Great Fortitude
5. Combat Expertise
7. Improved Feint

Mythic tier 2:
1. Dual Path, Mythic Weapon Finesse
2. Legendary Weapon (Elven curved blade - Upgradeable, Undetectable)

The only items off the top of my head are some pots, the legendary curved blade +1 (getting keen on it soon), and a ring of invisibility. I believe there's a headband of int +2, dont have the character sheet ATM though.

Anyways, I think with mythic tiers there's a lot of great options possible, but I suppose 25 point buy mythic games make almost anything viable.

I think at tier 3 I am going for mythic improved feint (swift action makes life so much easier.) and the Archmage passive armor feature (it's like 3 + your tier? So right off the bat it would be 6 free armor.) I was thinking of taking mythic combat expertise later as if I'm doing feints properly, hopefully I'll be hitting flat-footed fairly often and will be able to afford the penalty to hit.

Arcane strike with mythic seems like it will be pretty good... much later on when its +2 or 3 to damage. For now it seems a bit meh.

Anyways, if anyone has any ideas or cool suggestions, I would appreciate it, thanks!

I would suggest maybe swapping out the following:

Great Fortitude or Improved Feint > Arcane Strike
Dual Path > Mythic Arcane Strike

Reasoning: You already have undetectable, improved Feint isn't exactly necessary, with undetectable and invisibility you're going to own face (and eventually greater invisibility),

Mythic Arcane Strike would allow you to slap on some relatively useful abilities whenever you want, such as Bane or Keen (that way you don't have to spend the money to keen it up, or you can add keen until you CAN spend the money to keen it up.)

Just my two cents, other than that, amazing!

I would suggest some more balanced stats.

What mythic path are you choosing? Trickster and Archmage are both very viable paths.
