Question about wisdom

[Erati]

Hello,

This question could be really stupid or quite interested..(note I am 44 so if thats why my wisdom turning into mana is acting this way then let me know) but heres the situation

I am currently sitting here at 203 wisdom, so normally i thought im max'd and the 3 wis over 200 is only adding 3 mana....however if I take off my 3 wis earing to drop to 200 wis, the earing actually added 16 mana and not 3.....also if i take my my split paw gloves and go from 203-201 the gloves added 10 mana not the expected 2.......if i put on my lizardcale mantle and go from 203-206 I gain 7 mana, so I am pretty confused about how this works and wondering if our forumla is different here

anyone know whats goin on here and whats the actual formula or real cap at play here....or is it bc im 44

Thanks, sorry if I made anyone's head hurt reading this haha
