I came to realise preparation is key as a solo player, I made a base close by with a chest full of healing, winter cloaks, and anti freezing potions, i took 400 fire arrows, 100 poison and 100 dart arrows.the problem for me was dealing with the mobs , i had a stone golem, 3 or 4 normal dragons flying over and packs of wolves all coming for me. And the damage to the bows was a problem too. I got him down to the last bit of health and couldnt repair my bow as he destroyed the workbench. Back to square one again! . F.
