This build is great for taking out the smaller monsters, but also is great for PvP. The spinsickle does surprisingly high damage to single targets as well, so it's really a good choice for dealing with the swarms of monsters and fighting others 1 on 1.

When dealing with a group of monsters or fighting in PvP, you could choose to focus your gear more on damage or health. Since the spinsickle already has really nice damage and you don't want to be super low on health after finishing off an enemy, you want to equip gear that will replenish your HP quickly. This makes vampire teeth, vitamin shot, revitalizing mist great options for that, and even quickly giving you HP back in the middle of your fight. Healthy snacks and life jacket also help you live longer, which is a huge boost when fighting another player.

Unstable beam is a better choice than unstable lazer in PvP. Because the monsters aren't that strong in PvP, you don't really need a significant damage buff when killing them. So the extra damage that the beam provides over the lazer is good advantage when fighting a player, especially since there's often not any monsters in the way when fighting them.
