Variable crystal growth

I've mentioned possibilities like this before, one such example in the stats/leveling topic:

I'm pretty sure I contributed something similar to a discussion before earlier, too, but I can't remember where that was. I think the curse tied to gameplay would be pretty cool. I actually expect it to be, some way.

edit: Oh, this also relates to another gameplay idea with Pure Miriam. Rather than the stat/magic-boosting nature of the curse getting stronger, Pure Miriam could instead be an option to play where you opt out of using crystal-related powers, but holy/pure sub weapons or items are present (or more effective). This could be more of a style of game with emphasis on candle drops and other classicvania elements.

Maybe as Miriam levels, she gains Crystal Slots that can be filled with Red, Blue and Yellow Shards. There would be six ways to fill out the Crystal Picture.
Pure Red: Boosts Miriam's strength and defense. She'll hit like a truck and take hits like one too. Gains passives based on 1. Hitting things hard and 2. Taking hits.
Pure Blue: Boosting Miriam's magical capabilities, Pure Blue focuses on long distance combat.
Pure Yellow: Speed and evasion are king. Get in, hit 5-7 times, dodge attacks, kill, get out.
Purple: Battle-mage. She can hit well with a weapon and magic.
Orange: Physical glass cannon. She'll hit really hard, but can't take as much damage.
Green: Magic thief? Didn't think this through.
