Prodigy and Master seem both needlessly complicated (see number of posts about Prodigy + Level 1 spells) and also very restrictive, only affecting one spell in your already limited spellbook. That feels the opposite of a ‘prodigy’ to me.
I am considering house ruling these moves to this instead:
Prodigy – When preparing spells, the total levels of spells can’t exceed your level +2.
Master – Replaces Prodigy. When preparing spells, the total levels of spells can’t exceed your level +3.
This seems to be much simpler and cleaner, and much more versatile. It also resolves the issue of Prodigy + Magic Missile and all of the weird issues that creates. Is it a cantrip? If not, can it be memorized 100 times since it is effectively level 0? etc..
Has anyone else used a similar house rule? If so, how did that work out?
