My results for Sunblessed vs. Void vs. Sentinel have been posted. Interpret these results however you want and I implore you to try to replicate these results.

Pl'Othozz is not way to hard to solo lol, it's quite easy if you use the armour pot. You won't use health pots as much either.
I decided against spending 1500 gold for each run for 12 runs total (18,000 gold) for the sake of this guide. I know Tanker's Ale makes a lot of fights easier, but without it, Pl'Othozz is pretty damn hard I must say.
