How to play with this build
Try to evolve Axe to Death Spiral or King Bible to Unholy Vespers as fast you can. These Weapons are your main damage dealers.
Once you get one of these evolved weapons it’s almost impossible to lose (unless you start walking into creeps)
To evolve the weapon you need to upgrade it to level 8 and have a corresponding buff (level1 is enough). After that an elite creep will drop a chest with evolved weapon.
Do not upgrade a weapon to level 8 if you don’t have a needed buff. Otherwise you may not able to evolve it (maybe it’s not how it works but I prefer not to risk it)
You may take any weapon (except for Pentagram. It removes elite creeps making it harder to scale up) after getting these 3 but an AOE weapon is preferable. You may also take almost any buff (Attractorb and Clover are useless) that will help you with your playstyle.
