So if you have a ton of Ancient-ithil coins, Star-lits, Scrolls of Empowerment, Heritage runes, etc.. and want to know what to do to prepare for the maximum payout with minimal effort to use up those resources, do this:
Minimal Imbued Steps:
1) Get a third ager
2) Apply scroll of delving
3) Apply crystal of remembrance (if you have them)
4) Apply Stat legacy (Tier 4 agi/vit/might/will/fate etc..) to the crystal of remembrance blank spot (saves 2 empowerment scrolls)
5) Max out experience to 70 and reforge it all the way
6) Apply points to max out the DPS/Healing/main legacy (first on the list) on the LI. Only this one counts.
7) Imbue the item
8) Apply 15 Star-lits to get the dps/healing/main legacy stat to Tier 54
9) Apply SoEs to get every legacy to Tier 54
10) Apply heritage runes to max out experience
This gives the following return:
