Been thinking about this and have a massively over complicated idea to chuck at this to see if it can be moulded into something useful
Embossing - available to special items (crystal, holycrystal, celestial, elysian)
This is a multi step process that can generate much improved items if you're committed to it, hopefully something that can keep the most obsessed players busy without making them completely invincible, while giving everyone else something extra to play with
Step 1 - create an EmbossVial. To do this there will be a special NPC that you can 'salvage' special items (crystal, holycrystal, celestial, elysian). EmbossVial will be one of 7 types, completely random chance, you cannot control which you get (Accuracy, Agility, Health, HealthRegen, ManaRegen, PhysicalDamageReduction, MagicDamageReduction). For example if you salvage a crystal item you could get a 'CrystalEmbossVial of Accuracy'
Step 2 - use an EmbossVial on a special item, you can only use on an item of the same 'level' as what you salvaged, so you create an EmbossVial from a HolyCrystal item, you can only use it on another HolyCrystal item. This will turn the item mythic with the appropriate stat added, as per the table below
| Crystal | HolyCrystal | Celestial | Elysian |
Accuracy | +1 | +2 | +3 | +4 |
Agility | +1 | +2 | +3 | +4 |
Health | +50 | +100 | +150 | +200 |
HealthRegen | +5% | +10% | +15% | +20% |
ManaRegen | +5% | +10% | +15% | +20% |
PhysicalDamageReduction | +0.5% | +1% | +1.5% | +2% |
MagicDamageReduction | +0.5% | +1% | +1.5% | +2% |
Those stats seem to not make a huge difference, but here's where it gets beneficial. The total effect is multiplied by the number of embossed items you're wearing
For example, if you have 4 celestial items embossed with health, they'll be giving you 150 health each which is 600 health, but then that's multiplied by the number of items, so x4 again. So wearing all 4 of those items at once will give you +2400 HP
Even with stuff like holy crystal, say you have 6 holy crystal items all embossed with hp regen, that's going to give you +360% hp regen, definitely worth an investment!
At the top end of the scale, say you have the maximum number of items (10) all elysian and all embossed with agility, that's a potential +400 agility, utterly over powered, but a justified reward for the fact that to reach that point you'd need to salvage around 70 elysian items which isn't going to be a simple task for anyone
