How to use Dex or Cha for attack rolls?
 

I have this homebrew warlock pact that lets one cast eldritch blast through a longbow using the higher of Cha or Dex. If using Dex, it's a ranged-weapon attack and damage bonus would be Dex as well; if using Cha, it's a ranged spell attack and damage bonus would only apply if the Agonizing Blast invocation is in effect.
Copying a longbow and changing the damage to 1d10 was easy enough.. but I can't see how to get a Dex/Cha sort of modification and am still in the cut-n-paste phase of eval scripts, so have no idea where to begin on something like that..

Thanks in Advance :)

Have you tried using the 'Change Spell Attribute' adjustment under 'Class' on the Adjustments tab.

Then just Check or Uncheck the adjustment as the situation requires.

that could work. I'll give that a try and see how it works for me.

thanks!
