I have an Elite Knight lvl 148 at this very exact moment. I decided to apply an imbuement for Intricate Void (Mana Leech lvl 2) on both, my axe and helmet, however, it is not resulting as I expected, perhaps there's something I am misunderstanding.
With these, I get 10% mana leech with a chance of 100%. Now, let's put an example.
I get surrounded by 8 Lizards Chosen and I use Exori Gran. Let's assume I hit 500 with the Exori Gran. This means that I should gain 50 mana points for each Lizard Chosen since 10% of 500 is 50. Since I have 8 Lizards on me, that means I should gain 400 mana points (50 x 8 = 400). Exori Gran has a cost of 340 mana points, So, as far as I understand, if I have 400 mana points, and then I use Exori Gran in this scenario, I should spend 340 mana points and then recover 400, which should leave me with 460 mana points.
So pretty much, unless I am missing something about the formula behind this, my mana bar should fill up when in scenarios like this one, however, It is not happening like that. Of course, I notice some improvement vs having no imbuements, but I would definitely say I am not leeching 10% mana of my damage dealt.
Please let me know if there's a part on the formula I am missing or what is your experience so far with imbuements. Why am I not getting more mana when this scenario occurs?
