- About 80% of the gold goes on +15 to +20. +15 costs under a fifth of the full price, so push to +20 only on pieces you'll keep.
- Rarity barely changes the price. A 6★ Legendary costs 1.46 times a 6★ Common to max, and the Memorium is the same for every rarity.
- Stars change it a lot. A 6★ piece takes 33 times the Memorium of a 1★ piece, against 4.6 times the gold.
- Accessories cost the same as gear of the same stars and rarity.
