Just sharing this since i've seen quite a few missing out on this. Enchanting Heart/Soul/Pet atm to +14 before doing the final upgrade to "max stage" will save a lot of gold or time. You will obtain +16 max after the final upgrade doing it this way. It's 25% chance for 12-13 and 13-14 with old system and also lose 1-2 levels (depending how high + atm) if fail. But it's cheap to try it compared to using 13 or more sacred vials per attempt with 4% and later on 2% chance (+10-16). Even with the pity system. Only took soul as example heart and rest have different amount of mats and % chance. And reaching above +15 Max Heart/Soul is a huge advantage since you obtain extra stat. 3000 Debuff damage or less / 10% Mystic Damage or less / 1-3% crit rate (one of those you can obtain). Anyway i hope this can help ^^
