What kind of stats would you need on the G.Axe for it to beat Perdu's 5acc 10att?
For example, would 1 base damage and 2 double attack be enough?
We know from BG screens so far that the known max for each category is DMG+6 (base damage 97), STR+5, Double Attack+2, Att+5.
Let's see what the effective difference is:
Base damage: +2~3 (75% 2, 25% 3)
Attack: -1~2 (75% 1, 25% 2)
The base damage increase is going to be somewhat under 2%, as is the DA+. (Total it lands somewhere in the general range of 3.5%.)
Accuracy is going to be at least a 2.6% loss (dropping from capped to capped-minus-5). If the attack is enough to drop your damage by more than 0.8%, you're sitting at below 266 attack (which means "no, it won't drop your damage by that much").
I'll leave it to someone else to figure things with a "normal" build as to how high your hit rate needs to be for this to win over Perdu, but with ideal augments (that'll never
happen) it should if you're capping accuracy with Perdu (but only marginally - the ~0.4% you're looking at amounts to an extra 1 damage per hit).
