I have done some calculations for this myself and was looking for official numbers. I use Magelo right now testing some stuff and I think it is using Blue Formula and Green Formula is different.
On Magelo if I go above 200 WISDOM it diminishes the mana you get but it does not go to 1 mana per wis which on Green I believe is the case. I went from 200 WIS today on Green to 218 with a buff and with a new item and when I cast a 300 mana spell, I lose 14% mana every time, whether I am at 200 WIS or 218 WIS .
Using your formula.
(200 - 199) / 2 = 0.5
0.5 is greater than zero so set MindLesserFactor = 0.5
MindFactor = 200 - 0.5 = 199.5
199.5 is larger than 100 so formula:
(((5 * (199.5+20)) / 2) * 3 * (50) / 40 ) = 2057
I had +35 mana items
2092 mana.
I calculate my mana as 2135 by a basic old formula I found on an old EQ site.
But when I calculate my mana on the fly I have 2143. By watching how much mana I use when I cast a spell.
All are pretty close together though... although the formula you have matches Magelo almost EXACTLY. I suspect the blue formula is definitely what you have posted and I suspect the Green formula is what I found on an old website which is much more simplified because post 200 Wisdom each Wisdom is +1 mana or +0 mana, can't really tell.
My formula for Green mana which seems to be very close to reality is: ((WisOrInt/5)+2)*Level)+ManaItems
I get 2135 for 200 Wisdom and +35 Mana for this formula and as I stated before. When I use a 300 mana spell, it costs 14% of my mana which is 2142 mana. I'd love to know if there is indeed a diff formula for Green era versus Blue from a developer but I am sure we won't hear that -- sometimes the testing mana cost using % on the mana bar is pretty inconclusive.
Great find, sir.
