Oh , yes i forgot about heavyhand.
2h gris is a weak tank, are you suggesting the cleric should be the tank? If cleric goes tank, then the best build is joining cleric guild and using Battle Prayer.If you arent playing on Iron man then intervention is not important and its much easier to make 2h grisenda, and if you kill Minotaur king then you can have his axe on her , and thats top grade weapon , much faster than you would get something from end game places. Not saying that you are wrong , but for a new player, he can first go for something that works right now ,to explore game and have fun.
Vicious is an average modifier imho, you do extra damage when enemy is below 30% hp, but you need to reduce his 70% first, without any bonus. Ancient fang provides high raw damage (4-10) with very high attack speed. It goes well with Duel and other attack skills. Also investing only 1 point in Arbenos Might will give you a noticeable DPS boost (don't use it on fire elementals though )Im actually using Hirge, and she is rlly great fr me(mostly cuz i rush in and do damage, but take a lot of hits.) First time playing an rpg and im not great at it. I have heard rlly cool things about ancient fang, but i dont know if despair is better( Vicious II is really good)... And also with Hirge, i dont need to spend a lot of money fr her armour as i can give her my old ones lol
