A friend developed a homebrew warlock class that uses intelligence as a modifier (Warlock INT) which I am using.

When I have tried to multiclass with this character, ALL multi-class options are crossed out, with a line of red text under each one reading "Starting class does not meet multiclass prerequisites: CHA 13 (10)". So, it seems that the prerequisites for all classes have been set to CHA:13.

I'm not able to upload a photo either, it just asked for the source and description without giving me an option to upload. 

So here's the description of the image I wanted to upload, sourced from a screenshot from my monitor. 

No, the “starting class” (warlock) has a prerequisite of Cha 13+ to multiclass. When multiclassing, the prereqs for all classes must be met. Just because the homebrewer changed the spellcasting ability from Cha to Int, that doesn’t change the multiclassing prerequisite.

Thanks for the explainer. Is there a workaround? 

PS- You cannot upload images to the forums here, only reference an image that has been uploaded to and is hosted on another site, such as http://Imgur.com. Here’s a handy vid on how to embed images into DDB forum posts:

Yes, you can turn off multiclassing prerequisites on the Home tab of the character builder for that character.

thanks! appreciate it :) I changed the stats, took the multiclass and changed them back. 

That works too.
