how can i get the better graphics

First, this doesn't go here, this belongs in the Beginner Sanctuary, or Support section.

Clan events is for clan- events.

To get better graphics, you need to have a really good graphics card. If you are on a laptop, it will most likely not be able to run shaders. To check if you have shaders ('Good Graphics'), open Toribash game. Go to options, and check the box that says shaders. Then go to singleplayer. If the graphics improved, your graphics can run shaders.

Moved to beginner sanctuary. Ask non related support questions in this subforum please.

Slycooper answered your question pretty well.
