I'm having troubles. I'm fine until Berserk.... My best units like always die because of berserk. I haven't even gotten to Nergal yet.

Pure Water or high Res is always good. Send your highest Res Units to waste out the Beserks, then hope they are not affected. If they are, just move your non mounted units to the back and have another high res guy without weapons to take the hits.

Or just give them no weapons ^.^

You could always try wasting its uses with a unit with high avoid such as a swordmaster.

Yeah, that part of the chapter always beat the heck out of me. I always ended up trying to rush to kill that Druid.

@ Dragon:

Normal avoid doesn't affect stave accuracy.

Stave avoid = (Resistance x 5) + (Distance from enemy x 2)

Fkital's got the right idea but see if you've got any restore staves in the convoy as well.

I'm hoping that you have someone that can use a staff. Get out a restore staff if you have one. Otherwise, just have a high res person take all of the hits while everyone else is out of range.

I'm going to make a weird suggestion that you try mine-glitching the guy (I think it's a Druid) with the Berserk staff. This is only a last resort if absolutely everyone in your party has terrible Resistance and Athos won't work for some weird reason.
Not sure about this one, but it's worth a try. Unless, off the top of their heads, someone can contradict me about that Druid's priorities.
1) Get Paladin with good Resistance.
2) Get other guy with bad Resistance.
3) Get mine. Give it to the Paladin.
4) Place Paladin near door to Nergal before killing Lloyd and Linus.
5) After killing Lloyd and Linus, put that bad-Resistance unit at the very bottom of the Druid's Berserk range.
6) Take Paladin, put him on the square below where the Druid would have to go to use Berserk on the low-Resistance unit.
7) Drop mine in the square where the Druid will go. Use mine glitch.

What I normally do, is just put whichever Falcoknight/Paladin I used by Nergal's door BEFORE I kill Lloyd and Linus. Then on the next turn I kill them, and have the Falco/Paladin take out that Druid.

Of course, there was the one time where this didn't work and I was in a mad panic to take Nergal down. ;>_>

I usually just use the silence staff from one of the villages in the chapter where you get Geitz. The staff can effect anyone on the screen if Athos uses it. Use it on the druid.

Athos uses bolting. always works for me.

I always kill Nergal with units that actually have the ability to AVOID Berserk. HHM is hard, I know, but get some 20/20 units in, and Nergal is dead before the Druid can use Berserk the second time. Or move all other units than Athos back , wait with him in Nergal's range, next attack, and whee, he's dead.

EDITZ: Nergal, not Athos.

have a guy by the gate before you kill all the bosses. and they can take out the druid that has beserk
