4) Draconic Vigor, Draconic Aura are both listed as "general feats" - so doesn't work by RAW - but perhaps RAI?
Draconic Vigor is already considered a draconic feat (Dragon Magic pg.17) as for Draconic Aura, personally as a DM i always house rule it to be a draconic feat...it is not something gamebreaking so some dm's i know usually accept it as a Draconic feat.
1) skirmish - well - you could go barbarian 1 for pounce. Scout for some skirmish.
I quess it would work with channeling, but not with full arcane channeling. So you lose the best part of being a duskblade.
You can get an light armor enhancement that grants mobility - personally we play with the (house?)rule, that you can qualify for a feat/prestige class with an feat granted by an item, but loose all abilities in the chain if you take off the item/it's dispelled/antimagic field - until you gain the ability again.
You might be able to make a desent duskblade9/Scout5/swiftblade7. (Edit: Desent but in no way as effective as a duskblade 13+)
(more edit:)And this only gives you +2d6 skirmish and well its 21 lvl's only getting Bounding Assault, at lvl 21. Okay - drop swiftblade...
Maybe with some highland stalker - but then you just loose more spellcasting... Skirmish I can't make it work in a duskblade build
My bad
I wasn't clear enough... I was referring more to the whole concept of "get-in -strike and get-out" than the actual ability, skirmish
I am aware it will not be as a good as a pure duskblade or Duskblade LV.13/Something Else X
But i am interested in giving it a try...
Here is a little feat line-up that i thought of:
Human Duskblade
(Lv1) 1. Dodge (Human Bonus)
(Lv1) 2. Mobility (Item bonus OR flaw bonus if DM doesn't accept , an item granted feat to enable you to qualify for others feats requiring the feat granted)
(Lv1) 3. Power Attack
(Lv3) 4. Spring Attack
(Lv6) 5. Elusive Target [Tactical] - Complete Warrior p. 110 personally i consider this to be an awesome feat (pity for the requirements though)
(Lv9) 6. Arcane Strike
(Lv12) 7. Bounding Assault
(Lv15) 8. Knowledge Devotion (Or Obtain Familiar if you take a second flaw, in which case you would learn Knowledge Devotion earlier in your career)
(Lv18) 9. Rapid Blitz
I was thinking of maybe multiclassing into a fighter for 2 levels for the bonus feats, but i am not so sure....The other option i guess is entering Swiftblade(in which case most of the feats in the above list would have to be rearranged) but I am not sure how i can qualify for it considering that the only way for me to fullfil the requirements for it would be to have a Drake helmet with haste in it...
What would your thoughts and suggestions be?
