-in order for this tricks to work you need to unlock the skill master. as it unlock a passive skill on each class.

the one we will be looking at is :

this is the ability we will be exploiting to have... infinite hitpoints! kinda...

to make things easier for your run, I recommend ice bombs. as it melts foes and bosses alike

"Waiting for the last moment to defend an attack will grant you one armor orb if you have none."

the last moment itself is when the white shield hitbox collides with an enemy attack or projectile as shown below.

if successful, you get an armor orb if you have none.

however an armor orb has a special trait.
No matter the damage you take from one instance, only the armor orb will be lost.
a 2 damage orc swing will only take the armor orb off and health stays untouched.

...which means if we find a way to get this armor before getting hit again, you are essential invincible:)

even learning all the patterns, it can be tricky to block perfectly everytime and also risky as there is input lag after lifting shield up leaving you vulnerable.

but what if... hear me out... you block your own projectile?

a warrior is fun but how about a warrior that shoots fireball?
this item has a chance to shoot a (slow) moving fireball.
most of the time your 3 hit combo will shoot 1 or 2 of those everytime.
And... yes you can also block it the moment it is shot as the shield button is almost instant...

---
basically once your armor is gone, go on the defensive and attack followed by block to restore your armor. it works on most case as you dont always shoot a fireball (id say 60%?) but as the armor itself block an entire instance of damage you can play safe with this.

as a side line this item makes it easier to block foes projectiles, and really helps against the final boss

--If at all possible save this necklace in the altar to always have it with you on your run.

an additional trick that works well with warrior is petrifying finger. Shoots a petrifying shoot behind you.

the way to use it efficiently is start of with freeze bomb, attack for 6 seconds, attack behind you and wait till bomb is recharged again. rince and repeate to also kill anything.

with mobs, you can alternate between attack and petrify to not leave them a chance to retaliate.
This will trivialize most fights too.

thee hardest challenge of all is the abnormally bulky 2 phase final boss: EVE.

now I understand the final boss must be hard to kill but the boss health is too high even with 4 damage ups...

anyway some tips:

--revive gives you a second chance (duh) and retores all life if you find it early go for health ups as any hp technically double value against eve if you still have it.

--avoid at ALL cost the PBOD(purple beam of death). it is easily telegrarphed as blue energy comes to him 1 sec before. you *can block it but i rather dodge or use invicibility here.

--final tip: Good luck:) the only real tip here as for all game with hard bosses is to persevere.
The joy of roguelike is learning through death. learn what went wrong and adapt.

Good luck:)
