Turning a Spell-like Ability from Touch to Ranged

[yaluckyboy09]

So I'm going to be playing a Warlock in an upcoming campaign and had my eyes set on the Curse of Despair Invocation, but the fact that it's got a range of Touch seems like a problem. Is there a way to make it have more range?

If you use a wand of spectral hand you could I think use it to deliver touch SLAs.

If you take obtain familiar and improved familiar for an eyeball beholderkin. It can turn any touch spell given to it into a ray. The hitch is that it's never addressed whether familiars can deliver touch invocations like they can deliver touch spells. Obviously this is rather a sub-par option due to cost.

The Disembodied Hand invocation from CMage functions as spectral hand if you think you can spare the invocation.
