So, what you need for unkillable beast? It is easy, you need just roll atribute on your sword, that converts damage in to sheald.

Then max your passives for mele and aoe. Just watch my screenshots, it is realy easy

for even more damage in this build, crits are completely removed, instead of them we have poison, bleeding and perk "grinder" in this version and with the type of sword indicated in the screenshot, you can safely go through missions 6 levels higher or more

Итак, гайд для русских.
1) выпить водки
2) найти своего медведя
3) найти меч с пассивкой которая превращает ваш урон в щит
4)следовать скриншотам которые я добавил
5) вы офигенны
