Things I need?

I find him easy, i always go for an all out attack, Zidane,Steiner,Freya and Amarant, i usally kill him before he get's me. If you.ve got Auto-Regen on you don't need a healer. If Necron casts Doom on someone, use a pheonix down on em. Also make sure you've got the best weapons/armour on everyone.

I have the best I can on everybody. But he still beats me to scrap.
I have auto-regen, and is useless. It heals way to less. NEcron is hard and unbelievably stupid. Kuja should've been the Final Boss.

Everyone says that. Don't get all stressy cos you can't beat him.

LOL, nah, don't hate him, he's cool, but annoying. I've been away for two hours, now I'll try beating him again.
I would say, train some more, but that's useless, cause his Blue Shockwave reduces my hp to 1.
If he hadn't Grand Cross, he still wouldn't be all that easy. Aw, I'll defeat him, somehow.

Auto-Regen is good for Blue Shockwave. To me (and most people, as far as I know) it's a necessity.

Look at the attack pattern of Vivi_Ultima.Necron always attack in that pattern so if you fllow his way,you might stand a chance.

EDIT:Plus a tad bit of luck.

[Elpizo]

He's dead. Actually, I slaughtered him three hours ago.
I was lucky, he only used Grand Cross two times, which doomed some characters and braught their hp to 1. Nothing serieus. And Zidane and Steienr came in Trance.
It's strange, I tried this morning 7 times, and I got my ass ahnded to me (LoL), then after 4 hours, I try again, and I win in teh first try. It can only mean one thing; You need luck when taking on Necron. Hoping he doesn't use Grand Cross too often.

I'll post a "My thoughts on this one" topic soon, like I did with FF V.
