yes, i know. druids, must have druids first. the key point about duskblade is that it leverages a lot of tech that exists in ddo today. as such its a lot less dev intensive than the animation for druid (although we know they are coming).
what is a duskblade? its a melee wizard who can channel spells through their weapons. http://www.wizards.com/default.asp?x=dnd/cwc/20060905a
key synergies with current tech
the key tech we'd be leveraging is the monk ki attacks through weapons. this tech would be utilized to activate a spell as an attack.
key changes -> in the current spell table each spell you take would have 2 icons. one that represents the spell being cast without an attack and one that represents a melee attack with that spell.
for example, you have chill touch as a spell for a duskblade. you'd attack by using the melee attack spell icon which would initiate the attack. if it hits the mob it would do melee damage + spell effect (in this case 5d6 + 1 point of str damage).
Other Feats
Armored Mage (Ex): Normally, armor of any type interferes with an arcane spellcaster's gestures, which can cause spells to fail if they have a somatic component. A duskblade's limited focus and specialized training, however, allows you to avoid arcane spell failure so long as you stick to light armor and light shields. This training does not extend to meadium or heavy armors, nor to heavy shields. This ability does not apply to spells gained from a different spell casting class.
At 4th level, you learn to use medium armor with no chance of arcane spell failure.
At 7th level, you learn to use heavy shield with no chance of arcane spell failure.
these concepts are in the game, but would have to be added as specific feats
Combat Casting: At 2nd level, you gain Combat Casting as a feat.
this feat exists in game but it isn't anything like it was way back in mod 2 or 3 time frame. i guess the biggest design question is whether a spell can be interupted if it is an attack. the current tech says no it can't (see monks).
Arcane Channeling (Su): Beginning at 3rd level, you can use a standard action to cast any touch spell you know and deliver the spell through your weapon with a melee attack. Casting a spell in this manner does not provoke attacks of opportunity. The spell must have a casting time of 1 standard action or less. If the melee attack is successful, the attack deals damage normally; then the effect of the spell is resolved.
for simplicity sake, i think you give this feat at level 1 to a duskblade for duskblade spells.
At 13th level, you can cast any touch spell you konw as part of a full attack action, and the spell affects each target you hit in melee combat that round. Doing so discharges the spell at the end of the round, in the case of a touch spell that would otherwise last longer than 1 round.
this one is a little tougher, basically instead of one attack with a spell being fired it is lingering for 3-4 seconds. i'd probably extend it for 6 seconds like moment of clarity.
Spell Power (Ex): Starting at 6th level, you can more easily overcome the spell resistance of any opponent you successfully injure with a melee attack. If you have injured an opponent with a melee attack, you gain a +2 bonus on your caster level check to overcome spell resistance for the remainder of the encounter. This bonus increases to +3 at 11th level, to +4 at 16th level, and to +5 at 18th level.
concept already exists in the game
issues ->
Arcane Attunement (Sp): You can use the spell-like powers dancing lights, detect magic, flare, ghost sound, and read magic a combined total of times per day equal to 3 + your Int modifier. These spell-like powers do not count against your total of spells known or spells per day.
none of these spells exist in the game. they could probably be rolled into a magical training like feat
Quick Cast: Beginning at 5th level, you can cast one spell each day as a swift action, so long as the casting time of the spell is 1 standard action or less. You can use this ability twice per day at 10th level, three times per day at 15th level, and four times per day at 20th level.
not sure what you'd do with this one, maybe give quicken spell feat for free at level 10 or 15?
3rd level duskblade spells
there aren't many that are in DDO
