That damn bat lady on Devil May cry 3...I can only take like maybe an eighth of her energy off...I can't beat her i think she's impossible...
props for the DMC3 nod.
Yeah at first i was frustrated, cuz she kept k!lling me, but after the fourth or fifth try i got the hang of it. The trick is to get rid of the bats that's surrounding her, DT does the trick. Once that happens just take her out maybe 2 combos with rebellion or one combo with Agni and Rudra, but after that jump away from her cuz she's gonna do this huge orb blast coming from the floor. If you're far away from her, just keep shooting her with ebony and ivory(also dodging her projectile attacks and the spikes that come from the ground) and do the same thing that you did before.
When her life is half she'll dismiss the bats and trick you into coming close for the k!ll, don't do it. She'll make you pay for it by taking away more than half your life just keep jumping and shooting. With a lot of luck and trickster you should survive.
hopefully this tip helps you if ever you decide to try and beat Nevan.
