A few suggestions for the Lair's modifiers that would allow them to be much better-balanced than they currently are. This will include some of the same ones as before, but with changes to them as well.
{Vulgun's Proposed Lair Modifiers}
Vampirism: Monsters restore 30% of unblocked damage dealt as healing.
Gloaming Hall: The environment becomes significantly darker and visibility is reduced. Nameplates are also removed from players.
Trick and Treat: Increases the number of enemies by 50% but also increases the rewards earned from Cursed Chests by the same amount.
Meteor Shower: Causes meteors to fall from the sky, dealing moderate damage to all targets and causing rings of fire to disperse around the arena.
{Vulgun's Proposed Changes to Current Lair Modifiers}
The Floor is Lava: Now ignites significant portions of the floor that burn players when standing on them. These portions of the floor are seen through burning red cracks. Very hard to miss.
The Rot: Now applies only after an enemy dies and causes these pools to spread slowly over time, preventing players from being able to prolong Cursed Chest runs.
Employee of the Month: No longer guaranteed on mini-boss or boss monsters. Additionally, the chosen monster can now be looted by all players to grant more Color Fragments.
Anything with Cowardice: Cowardice now only applies when you're out of a 5 meter range of a monster for 5 seconds, but instantly applies all stacks if you are in a previous lair room.
Missed Opportunity: No longer reduces damage, but instead increases the recovery time of missed attacks by 66%. Does not stack.
