Arcus unit: We would price at 80 points, and we are fine with 7 of these slots being sealed upon delivery!
Additional slots: 50 points each to open each slot.

Master Quartz: Canon with Tear + Aqua Bleed, we would price this at 300 for those abilities plus the bottom portions (short term regen ability, wider arts range, increased potency of healing arts.)

Teara, Breath, Tearal, Holy Breath, we would price at 120 each, or you can do all four of these for a bundle of 300.
Recuria and Athleas, given what they do, we would price at 200 each.

Regular Quartz: We've broken this into tiers as well!

Tier 1: All spells 350 points
Tier 2: All spells for 750
Tier 3: All spells for 850
Tier 4: All spells for 900
Tiers 5-6: You're right, there is a chance we would absolutely say no to these. However, we're more than happy to review if you would like one from these tiers and work with you regarding a price and power caps so that the game doesn't break/Elliot doesn't die.

Orbal staff: Given its shifting abilities and magical abilities, this would be 180.

Crafts: You're free to gain one craft at a time for 120 points each. However, we're also fine with you gaining three of them as a bulk package for 320.

S-Crafts: Broken down this way due to their powers, etc.
Seven Rhapsody: 300 points
Remedy Oratorio: 350 points
