How to convert ranged touch/target spells into melee touch attack spells?

Question

Duskblades of 13th level or higher gain the ability to channel a touch-range spell they know into their weapon, and make a full attack with it. However, they know very few touch-range spells!

The duskblade spell list has many cool rays though, like disintegrate, or targeted spells like slashing dispel. I would like to be able to channel these spells into my weapon, and stab many enemies with them as part of a full attack.

The method needs to be achievable for a character whose first 13 levels are in duskblade. I already know about enlightened fist's Hold Ray, but I am hoping there is an option that doesn't lock in all 20 of my levels.

I'm open to Dragon Magazine and perhaps even 3rd party sources, but Pathfinder is off the table.

Answer 1

If you are open to a 3rd party source, may I suggest making a slight alteration to the existing feat Reach Spell and convert it into a new feat named "Close Spell". Which basically is a feat that does the opposite of what you are asking for. If Dragon Magazine is legal, I couldn't imagine that a feat like this would cause any qualms with the group/DM.

Close Spell [Metamagic]

You can cast ranged touch spells by touching the spell recipient. You may cast a spell that normally has a range of "close", "medium", or "long" at touching distance. The spell effectively becomes a touch attach, so you must succeed at a touch attack to bestow the spell upon the recipient. A close spell uses up a spell slot two [should probably be one instead of two here IMO] levels higher than the spell's actual level.

Answer 2

The prestige class The Ordained Champion from Complete Champion from complete champion has an ability called chanel spell it's not quite what you're looking for but it reads

Channel Spell (Sp): At 3rd level, you can channel any spell available to you that has one creature or more as its target into your melee weapon. Doing so requires a move action and uses up a spell slot or a prepared spell of casting time no greater than one standard action. The channeled spell affects the next target you successfully attack with that weapon, though saving throws and spell resistance still apply normally. Even if the spell normally affects an area or is a ray, it still affects only the target in this case. On a successful hit, the spell is discharged from the weapon, which can then hold another spell. You can channel your spells into only one weapon at a time. A spell channeled into a weapon is lost if not used within 8 hours.
