how to increase max hp???

You should buy Forehead protector.

@lvl 90 you have a base 1000 hp
+ Forehead Protector (Event) 1500 hp
+ Roga Xtal 1000 hp
+ Hp Boost 1000 hp

 

I want a forhead protector ahah. I want 7.8khp mage ahha

 

Well

Survival skill hp boost = 1000 hp
Forehead protector =1500 hp (event version)
Shield skills = (500+500) =1000 hp
Zega xtal =400 hp
Black Dragon armor
Straye garb
Vitality = also increase hp based on factors
Hp % + vit % gears
Hero scarf = 1000 hp (+vit 5% it's also very nice)
Nuretooth mask = 60% hp
Stier
Albero shield = 300 hp
Roga xtal =1000 hp
Hp 200 or 100 crysta (you also get 200 hp crysta from emblem)
Level up also increase hp


(Going away from topic I also want 8k hp for my mage for sanctuary skill effectiveness lol)

 

that was a special version from an event.
the standard forehead protector has less hp...

 

Yeah kinda creates misconception since I forgot to add "event"
I'm gonna edit thx
