Order of Souls Quests are way too hard for solo players

I enjoy playing the game sometimes alone, but doing the Order of Souls quests is nearly impossible alone. On small islands where you can use your ships cannon it might work, but on larger ones its terrible hard. You just cant beat 6-7 skeletons all with ranged weapons alone. Mostly you are dead before you even have killed one. The ghosts are impossible too, you cant use the ships cannon because you have noone making light, and waiting everytime 10 minute for the sun to get up it really boring. In the end you need tons of time for these quests and get a 500 gold skull.... thats not worth it.
