[Rappelz Epic 6.3] Renouveau VS Primal Scream

People thought that it was impossible to kill Primal Scream without using HL pets or asking HL to help us. So yesterday we made a 47-69 party and we tried again and again... And we succeeded.

Primal Scream has a deadly spell which can kill a full party instanlty (Dark Spiral-like, anyone who is in its range takes six dark magic balls in the face). However, we can prevent him from casting the spell thanks to a knight, a huna, a chaos mage or a bishop: seals and "Spell Intercept" can stop an incantation. He uses this spell every 28-30 seconds.
This boss can sometimes summon 5-6 very weak minions. These things have 7500 HP and don't hit very hard but can be dangerous for a mage.
Finally Primal Scream has an AoE which reduces your P.Def. (Log Split-like).

What is dangerous and makes him so difficult? Well if seals or Spell Intercept miss (you cast the spell but it does no effect), his ultimate skill will shoot your HP down. Each ball deals about 900 damage (no critical) to a buffed knight and the spell will OS assassins, a lot of soldiers who don't have much HP, hunas, melee pets etc. The spell range is just lower than Energy Beat/Fire Arrow and Lightning Bolts so you have to be very careful when you move. You have to recall your pet at your side after each skill if it is a RP, siren or BP (etc;) and think about the one minute-rule which can be really deadly.

Our assassin used a crossbow because he'd be OS if Primal Scream managed to use his dark spiral-like spell. Our soldier used a bow but switches when the boss' minions come and used a spear. A lot of pets are unsummoned or hidden behind.
I have to spam my "F1" key like mad: after each debuff or skill of my pets, i have to recall them next to me or else they died because of the dark spiral..

I'm sorry for the lags and if you wonder why I didn't use a lot of mana pots and failed one time my dual summonning, that's because I was focused on my F1 key, my spells and Rebby's HP. I know that I could play (much) better. I hope you'll enjoy the video though.

GZ everyone, I hope you won't be disappointed by the video. :p
