Managed to Solo an Ash Lord using the sniper rifle.
Died a--lot case of explostions and fire, but i did it.
Then two jerks showed up and murdered me for the loot.
for solo I recommend only doing mermaids, cannon cove, and wanderers
easy to see easy to hide and bright area
as well as having good spots to kill the boss for loot gathering
use blunder/sword combo and just constantly hit them near an ammo crate it'll make it fast so other players have less time to attack
always lead the boss to and kill them on the beach in a good pick up spot so when the loot spreads it's all easy to gather and harpoon
ashen winds are great for solo players so keep at it
finally managed to get the Loot from an Ash Lord fight.
... those Rage Chests are Dangerous.
