It seems to me that Dirna is far stronger than Ethereal Queen. Any of you know how to beat her the easiest and quickest way, again without cheating. I'm talking about LEVEL 99 Dirna.

After a few attempts trying to figure out how to defeat dirna, I've finally came up with a best strategy which depends on luck. By equipping offensive equipments and accessories, dirna's hp drains quickly. I use freya, lenneth and hrist as the main attacker and rufus as the tank. Sealstones that I hold have these following effects:
ATTACK 150%
RDM 1/2
ATTACK 150%
NO HP RECOVERY
PROJECTILE ATTACK 200%
MOVEMENT SPEED REDUCED
ALL STATUS UP

Equip everyone with the skill magician slayer. When the fight begins, make one of your characters (preferably rufus) with the skill free item use might potion to one of the attackers (I used it on freya). Keep attacking her from behind to deal twice as much damage as normal. Use charge break when needed. I thanked dhamon for using tome of alchemy on the shadows which I haven't try it though, haha. I agree with Torebaa. Getting a DA on dirna is tougher than other bosses in SG.

Hey guys, how to DA Dirna anyway? I've tried experimenting various equipments and my party are Dylan, Hrist, Lenneth and Freya. I used Dylan because he can deals damage around 300000 to female bosses a hit with 1 White Loincloth and 3 Power bangles equipped. The battle was always easy and I'm on my 4th SG run, but I can't seem to DA her. Do I have to farm Golden Eggs? Help...
