You have earned my sub good sir and thank you for showing the doom versions of the bosses i was very curious about the fights and how to get the other material for them.
When I fought him his roar stuned me for much longer and he chewed on me until i was dead. luckily i had my eternity mask on and a couple of thralls to keep him agro'd while i recovered. i forgot to use mimicry, i should have frozen myself as soon as he roared.
I used the blade and man. They need to buff the blade. Theres like only two good skills other than the 1st one. Spear and Duals seem broken against everything but mechanicals
