Out of curiosity, I generated alternate spell progression tables for D&D BECMI magic-users and clerics. There were two reasons for looking into this. The first is that 1st level characters start with only one spell (or none at all in the case of the cleric), which a lot of players stumble upon. The other reason is that by-the-book first level parties are incredibly weak, and especially in the case of the magic-user, they don't contribute all that much to a game session, other than role-playing or pitching ideas. It's all rather limiting. Spellcasters should be in the business of casting spells.
Entirely optional, this approach is a radical departure from standard game mechanics. No one is obligated to follow it--I'm mentioning this for the cohort of folks who "disapprove" of new ideas to an old game or any sort of attempt to change their habits. What I post here is only for those with an open mind.
There are plenty of house rules on boosting the numbers of spells 1st level adventurers can cast. Nothing wrong with this if that's the way you like it--it's your game. The alternate spell progressions sidestep borrowing game mechanics from other systems or fancy schemes tacked on existing rules. These tables also ensure that characters with lousy stats* still start with a good number of spells.
In their alternate spell progression, I did not want to give clerics as many spells as the magic-users. Zero wasn't an option, obviously. So I settled on just two at first level. I hummed and hawed about starting them with 3, but I erred on the conservative side here given all the cleric's benefits.
This approach changes the profile of regular games drastically since spellcasters have a lot more magic to throw around. On the other hand, earning spell levels 2+ is roughly the same as in official rules. These two tables do not alter spellcasting abilities all that much at higher levels either. At level 18+, the differences with official spell progressions are minimal, thankfully!
Let me know if you spot two identical rows in these charts. Thanks! For the elf's updated spell progression table, click here. Have fun.
