I was level 35, I always spend all my stat point to int and then vit, I only spend my skill on fireball + firewall + whirlwind + summon demon also few at another skill

with noble set armor mixed with unthrings set(I meet bug on raze and xanlosh so can't get full uthrings armor set, yeah only have cuirass and helmet ) my hp is 900 and my mana is 400 full equip with mixed resistance level 9 (because if I make for level 10 then it need malachite but I don't want use my malachite)

play on normal, on DKS I didn't meet that difficult or really trouble for me, when start to battle, the enemy get their weapon while u should flee to another wall then summon your creature and then your demon...............I don't know maybe play as pure mage more easy than play as pure warrior

my strategy is just cast fireball + firewall and then whirlwind and then don't let your hero body endure their repeatedly attack, try to flee to another are after cast that spell

if I can give vote, I will vote fight berhlin + Ygerna more difficult on FOV than when you face Zandalor + Lucian + their paladin at Ygerna memory
