asal damage is based on atk with mp being the multiplier - doesn't really have anything to do with int.
so the more atk you have the better your base, the more mp the better the multiplier. for instance, 10,000 atk cause you're full str and with a bunch of mp awakens lets say you have 2,000 awaken.
just for this demonstration i will only multiply these numbers together, well that gives you 20,000,000.
maybe for pure int your atk is what, 3,000 but with int awakes and everything your mp is still only lets say 5,000. which gives you 15,000,000.
now the way this server works, since you have damn near infinite stats it might be best to raise int a little bit in order to heighten the multiplier, cause you can have just sooo many things to str.
but its more benefitial to be full str than full int, because #1 as a BP you get a higher benefit with your atk per str ratio than you do your mp per int ratio in the asal calculating formula. #2 as a full str, which gives you a much higher atk pow, you get a lot more benefit with asal by using upcut stones and basically anything that adds % wise. (upcuts, piercing). after all a higher base with an added % gives you more of a bonus than with a lower base. IE 10% of 10 is 1, 10% of 100 is 10....get it. #3 your attack power is much higher as a full str, therefore you can still 1v1 mobs just like normal. after all you won't ONLY be asal'ing mobs to do your training, you need to fight them too...so best to take a much higher attack power build in order to train much faster.
