What mods can I use?

Are the mods better pvp, better hud and xaeros mini/world map allowed

I don't know specifically if they're allowed. However, under rules it says this:

We allow the following categories of modifications:

• Performance, graphics, and aesthetics modifications
• Armor, status, and HUD modifications (That do not give a massive advantage)
• Minimap modifications that are purely ground-maps
• Recipe modifications

The better pvp mod is allowed
The minimap you said you must use the fair-play version where it does not show entities or caves
Better Hud is also allowed

Minimaps are great but only if I pay attention to them lol me and my sister got attacked by a group of players on survival and we had no idea where they came from. Ouch.
Those all sound like they should be fine though

The mods you cant use for instance are Auto Planters, X-Ray, etc. This also includes any hacked client.

Closing thread as this has been answered already.
