what the heck is this

[Pocus]

Nerfix : you have an added incentive in concentrating your magic in a single path in doms II : some effects only appears in the Last magical level of power. So taking 4/4 in air and blood will protect you a bit from missiles and give a bit of bonus in strength, but taking only air 6/7 would protect you better against missiles, and give you an added advantage, unobtainable from any other source.

well this is what I understand...
