Command name

!a / !adventure

Expected Behavior

Normal spread of boss to general monsters.

Current Behavior

Adventure version: 4.0.0

There is about an ~80% chance that anybody who starts an adventure will generate a Dragon / Boss encounter.

Possible Solution

Steps to Reproduce

Start an adventure.

Context (Environment)

This has caused users to become disinterested in the adventure game because it's extremely difficult to solo Dragon / Boss monsters and needing a raid call about 4+ times an hour to get anywhere is quite extreme.

It's possible this drop rate has increased as one specific user has the ability to use hundreds of million/billion/trillion gold to NV and catapult their level to 800+ (of 1000?)

Is boss rate tied to user level(s) at all?

Yes, one user was able to NV multiple trillions of gold -- this might be an area to consider investigating of boss rates are tied to user levels / rank / etc somehow.
