I lucked out solo when I fought elder, I had a troll cave near by that as empty. and when I needed stam or health I could jump inside and do that. when I came out, I stood close to entrance and fired my arrows. His long branches that shoot out, most didnt hot me as I had the walls/roof of the bunker/cave to protect me.

Even with the greys coming at me, his branches agro'd them most times before they hit me the first time. yeah it may have been cheap, but I am not about taking advantage of my surroundings. I did die 4-5 times fighting him solo until I found this golden nugget.

I know when I fight the 3rd boss. I am going to scout the area for anything like this I can use for my advantage.
