Hello! This thread got me curious about the details of SCH's sublimation all over again, and I decided to do some testing of my own. Unfortunately, the data I came up with made me more confused than I began with. Here are the specifics.

I tested with a Hume(not Taru) character that has Lv95 SCH, four pieces of equipment(all NQ) that enhance sublimation, and 5/5 Max Sublimation. /RDM was used. Not sure if it makes any difference, but the HP merit is 11/15 and MP merit is 4/15. The test was done on the Leviathan server.

Naked (16 empty slots) 2HP <-> 8MP according to wiki
max HP 1328 / max MP 790
94HP depleted for 384 MP in (47tics x2hp = 47 tics) / ratio is 8.17MP per tic
estimated time: about 2min 25sec

with Savant's earring (15 empty slots) 3HP <-> 9MP according to wiki
127HP depleted for 387 MP in (42tics x3hp and 1tic x1hp = 43tics) / ratio is 9.0MP per tic
estimated time: about 2min 10sec

with Savant's earring and Siriti (14 empty slots) 4HP <-> 10MP according to wiki
154HP depleted for 390 MP in (38tics x4hp and 1tic x2hp = 39tics) / ratio is 10.0MP per tic
estimated time: about 1min 59sec

with Savant's earring, Siriti, and Scholar's mortarboard (13 empty slots) 5HP <-> 11MP according to wiki
max HP still 1328, but MP+15 from the mortarboard gives the new max MP of 805
173HP depleted for 385MP in (34tics x5hp and 1tic x3hp = 35tics) / ratio is 11.0MP per tic
estimated time: about 1min 46sec

with Savant's earring, Siriti, Scholar's mortarboard, and Argute gown (12 empty slots) 6HP <-> 12MP according to wiki
gown's +15HP and +15MP give the new max HP of 1343 and new max MP of 820
192HP depleted for 396MP in (32tics x6HP = 32tics) / ratio is 12.375MP per tic
estimated time: about 1min 42sec

-----------------------------------
At this point, I did three more tests, substituting the gown(since it modifies HP and MP) for one of the pieces.
Also, note that estimated times might be off by a second or two due to the delay in hitting /clock, and is therefore unreliable.

with Argute gown (15 empty slots) 3HP <-> 9MP according to wiki
127HP depleted for 387MP in 43tics / 9.0MP per tic / same result as using using Savant's earring
estimated time is about 2min 8sec

with Savant's earring and Argute gown (14 empty slots) 4HP <-> 10MP according to wiki
154HP depleted for 390MP in 39tics / 10.0MP per tic / same result as using Savant's earring and Siriti
estimated time is about 1min 57sec

with Savant's earring, Siriti, and Argute gown (13 empty slots) 5HP <-> 11MP according to wiki
173HP depleted for 385MP in 35tics / 11.0MP per tic / same result as using Savant's earring, Siriti, and S.Mortarboard
estimated time is about 1min 48sec

== Conclusion ==
This small amount of data seems to be in line with the 2-6HP depleted for 8-12MP recovery for a LV95sch info from wiki. What I find interesting is that the +15HP from the gown did not affect the result one bit, except for the +/- 2 seconds in the estimated time. I apologize if this was the wrong place to put this data, but I am really curious about the mechanics and the actual formula for calculating the MP returned. It would be great if someone could make more (accurate) sense of this minor data that I collected and shared here.

To Garota the OP, I see a similar pattern in my own testing where the more "enhance sublimation" gear we stack on, the less of a benefit we see, to the point where it almost looks like not much difference is made with the last piece of "enhance sublimation" gear. I do sort of agree with Arcon though that we (as the players' community) should try to understand the real reason(in the form of a more accurate formula?) we are getting our results before we report this as a definite bug. I thank you for bringing this up and I hope we find out something about this.
