i think there is something wrong with the mp cost on that skill. it says "mp cost 3900" but i used it in kartia group (full buffed) and it costed almost 1400 mp. anyone can check this? sorry if this has been posted already
i also was wondering about that. guess thats because wizard harmony and other buffs may decrease spell cost.
i think its all allright. the skills costs ~4000mp but: - superior casting mastery = -15% mp consumption - the skill reuses 780 mp instantly also to healer no buff only by using this skill i've lost 2444 mp. if i add 780 value to 2444 its 3224. 15% from 4040 is around ~604mp. 3224 + 604 = 3828. the rest (~200mp) is my misscalculation.
all in all , you have passive skills for decreasing mp consumption, the brilliant recharges to you as welll, u get the mana recharged overtime from the buff, u regenerate a bit mana while the 10sec buff remains, u have harmony of wizard (-mp consumption) and melodies which decreases the mp consumption as well = > not that huge amount of mana drained since the -% mp consumption stack over each other + if u enchant it at ~5-6 it will actually remain the same mana as before u used brillance, at +10 u get like 400to 600 mana bonus (last 2 examples are with mass mana gain)
