Can I see the numbers for this "you do a literal 10x more damage with a bar of beam"
If Devastate costs 2.5x as much as beam then again quoting your numbers that you would be able to have 4 and 1/2 rounds of devastate per bar, then you would get 11.25 rounds of beam per bar, which is definitely not 10x more damage.
in reality the 10x more damage was a big exaggeration.. you do around exactly double in a mana bar..
549(day's mana bar)-40 for aop=509
509/10(cost of beam)=51
70*51=3570
you will have to recast aop , but with mana regains it wont take but maybe one or two beams away...
now for devastate
549-40 for aop=509
509/23=22
84*22=1848
thus doing almost double damage...
edit: literal was a very poor choice of words for an exageration, but with the math that it is 20% more per hit and 2.5 the cost of mana it should be common knowledge it was an exaggeration
