So this one has encountered the Thriller… poor bastard. When I found my first Thriller, the sudden 10 or so hulks did indeed kill me.
Nowadays I do it for the lols, the hulks mostly attack eachother - if they try and take me on I’ll cut them to pieces with my trusty blade. The key is a quick weapon, good speed and a high enough DEX to troll hulks and dodge most of their attacks.
Although… yeah. The first time I killed the Thriller, armed with my fists and not particularly good armour, I pissed my pants.
