I see a lot of ppl still have Dmg problems,like some npcs instant kill them like Laiken+Razakel,Amdusias,even the noob Sassan

I dont know what are us do wrong but I dont have these problems,contrary in Dragon Knight Saga I am god ingame even in hard mode I can kill any boss/bosses like at the end of Halls of Echoes(all bosses+Divine/Zandalor)
I play with warrior 10 chars/8 warrior or warrior kind.
The Only problem what I got along my play in Divinity 2 Ego Draconis and then Divinity 2 Dragon Knight Saga it was in Keara's Fortress where 5 stupid lier Statues had no combination...but I found the answer on forum,in rest no quest problems or anything else I found all things and combinations without help,it's only about your Will.
But back to word,About instant killers some tips for Novice:
-The First and the most important
ALWAYS use your rolling capabilityes Left Right Jump.-
USE YOUR PET(s)!!!!-NEVER I repeat NEVER stay away from a ranger like Amdusias,Sassan and others who have ranged attack because they will smash you in seconds even if you are ranger or mage go close to him he will use his secondary weapon to attack you,no more ranged attack.
-Use potions combo like Rejuveneration Poti+Healing Poti or even Heal if you have
-Try to DONT jump in a large group of Enemy
-If you are a mage or ranger or priest try to use Charms which give Strenght,Dexternity,Meele resistance,ranged resistance because u get overcrits that will cost half of you life or when the ppl can see instant kills.
-Try to Keep you Hp over 30% and please RUN always not only when U are close to dead a little dmg is enough,they will not regenerate.
-After each greater quest completed go and take a look over what the vendors sell and buy what is better the money is not a big problem(in DKS)
-ALWAYS,ALWAYS buy the greater healing potions and rejuveneration to no run out of them.
-In Dragon Form try to put in Defense some skills are unuseful like polymorph.
-Like in real life in game NEVER subestimate yout enemyes only if they are above your level with minim 4-5.
-and again
ALWAYS USE YOUR ROLE CAPABILITYES Roll left right and jump!You can dodge a lot of dmgAbout Quests:
Is a matter of will there are no hard quests or unfinishable,only need to know the places
When you find something without help ... is an unexplainable feeling very good,try ut guys/girls
