I've been now having one little build idea here, but I'm not sure if it's any good.

Eldritch Swashbuckler (Warforged/Bladeforged 13 Sorcerer/4 fighter/3 Bard)

The thing I tried to strive here is simple: An eldritch knight which also benefits from Bard's Swashbuckling. The fighter levels are also there for the incoming update.

Stat contribution:

14 STR
8 DEX
14 CON
14 INT
6 WIS
16 CHA

Bladeforged can put the remaining points into STR or DEX, whichever they want. You can also eat some tomes to try to get OC into the build

Levelling should go:
1 Bard
4 Sorc
2 Bard
2 Fighter
2 Sorc
1 Fighter
7 Sorc
1 Fighter

The 2 Fighter levels at lvl 8 and 9 would be important to get for the feats (BAB +6), and also 1 level of fighter to get BAB to +8 at lvl 12

Feats:

1: SWF
3: PA
6: Quicken
8: (Fighter) Shield Mastery
9: Mithral Body
9: (Fighter) ISWF
12: Improved Critical: Piercing
15: Improved Shield Mastery
18: GSWF
20: (Fighter) Improved Shield Bash

After that, you can choose whatever you want really for epic feats. For example:

21: Cleave
24: OC
26: (ED) Perfect Single Weapon Fighting
27: Maximize
28: (ED) Perfect Two-Weapon Fighting

The enhancements could go like this:

Eldritch Knight:

1 Eldritch Strike
1 Spellsword x 3
3 Toughness III
3 Improved Magic Armor III
3 Improved Shield III
2 Martial Training
2 Light Armor Prof.
1 Arcane Barrier
2 CHA x 2
3 Shield Bashing III
2 Scroll & Wand Mastery II
3 Elemental Resistance III
1 Tenser's Transformation
2 Eldritch Shield
3 Doublestrike III
2 Eldritch Tempest

38 + 13 + 11 + 18 = 80 AP.

Of course this is all still theory crafting. And also this isn't supposed to be the highest DPS, more like a flavor build.

What are your thoughts on this build idea?
