[the homestuck man himself]

I'm on the boat of liking this idea, the more customization is given to the player, the better.

To adress the problems of confusion, if push ever comes to shove, you could in theory do what some games do when it comes to skill customization:

For normal skills:

Custom Skill Name (Actual Skill Name)

For skills that do not appear in the chat/invocations:

CUSTOM INVOCATION/SKILL NAME

(Actual Invocation/Skill Name)

This could be added to the other confusion inducing mechanics to a degree.

Skills like banquet and other racial skills be exempt from this. Invocation dialogue could be customizable too, but that would MAYBE trample on the toes of some lore if they are ripped straight from the texts we read from, but I'm unsure.
