The settings menu, or should I say music volume control, this particular menu is so under developed and underused its unbelievable that its even called settings. Some features may be asking a bit too much from the devs right now however I do hope some features make the cut.
SFX Volume: max by default, controls volume of mob sounds, player sounds etc.
Advanced Lighting: off by default, this toggles the lighting system (legacy and voxel)
Priming: on by default, toggles the priming mode on aimed abilities
Fireflies: on by default, toggles visibility of the fireflies at night
Particles: on by default toggles visibility of all particles
Block Requests: off by default, in on blocks all party, trade, duel requests sent by non-friends
DPS Meter: off by default, toggles a dps meter showing how much damage you dish out per second
Health/Mana Color: Allows color change of the heath and mana bar (color selected trough pop up brick color menu)
Boss Heath Numbers: on by default, shows a bosses current heath out of its max health in the bosses heath bar on the top of the screen
