Question of a new player about MP-regeneration

[Lyrica_Ashtine]

Shroud of Saint does NOT gives a flat amount of MP, it has a potency, which means it varies with your weapon damage. It feels 'flat' because you dont change your weapon very often.

Right, so as this became a topic now. I, once again, did some comparison with the High Allagan Crook (77 Magic Damage) against Maple Wand (11 Magic Damage). Same gear, just different weapon. This lead to the following:
Natural MP regeneration without shroud out of combat:
Crook: 318 mp/3 seconds or 1590 mp/15 seconds
Wand: 307 mp/3 seconds or 1535 mp/15 seconds

With shroud this lead to:
Crook: 530 mp/3 seconds or 2650 mp/15 seconds
Wand: 519 mp/3 seconds or 2595 mp/15 seconds

After extracting the natural MP recovery, this leaves only the shroud recovery:
Crook: 212 mp/3 seconds or 1060 mp/15 seconds
Wand: 212 mp/3 seconds or 1060 mp/15 seconds

So yes, I was wrong by 30 mp, my bad.

Now, how I did this: I switched to a crafting class and switched back to White Mage. This will make you start with 0 MP. Keep an eye out on the ticks and note them down somewhere. Use the first mp tick as reference point (zero point) and use shroud then and start timing. Shroud has it's own interval, but if you assume the 3s natural MP regen tick, you can subtract the natural MP regen from it from the total amount of MP recovered after 3 seconds. To find out the natural MP regen, both math as well as noting down the initial MP tick will do.

Also:

i will test this after i reached max lvl. atm i've put all points in mind.

by wich ratio do mind effect the healed amount?

There's some rocket science math involved for this, Cyclee. So no one can really give you a solid answer here. There are some existing formula out there on the internet, but most of them are outdated.
You can go by a certain rule of thumb, however. Although it's slightly inaccurate, it will give you a general idea.
If you have a i115 weapon and you're level 50:
5 mind = +10 hp/400 potency or +15 hp/600 potency = 25 determination
How mind and determination scales varies with the magic damage value on your weapon.

There's also the thing about crit, which is roughly 13-14 crit for a +1% increase. So this means that 13-14 crit will increase your average healing per cure by +0,5% - But this isn't very reliable or should be relied upon.

Remember: These aren't exact numbers
