Honestly, this plugin / feature is top tier!
it makes PVE or PVP servers extremely fun and gives a really neat way to entertain you and friends or solo depending on how the server owners configure it, this can offer players so much replay value too.
the loot table separation makes it even better and how well you can configure this, so you could even make difficulties that require like a clan or something to get rare or custom loots for whatever server you run.
Razors support and reply to support tickets or questions are also SUPERB, honestly doesnt get better than that.
