I was messing about with knives laying near the satyrs, something often done by random players.
Which gave me an idea. Akrabu mentioned using a tree to avoid an Elder Satyr's headbutt attack. This is possible but also difficult. What if it can be replicated with an artificial barrier?
As some of you might predict, the satyrs drank the beer and hopped over the knives. Attempt two:
This version was extremely successful. It avoided the headbutt and made soloing elder satyrs easy. Killing them without taking much damage is important to minimize the risk of being playerkilled.
The lullaby still has enough range to cross the barrier, so I suggest running and resting even when slightly injured - so you can avoid an unlucky chain of sleeps.
