First thing to try is verifying the integrity of your game files:
Steam > Right click on Battlerite > Properties > Local files > Verify integrity of game files
What also works in most cases, is locking the server you use to the second one on top of the server list:
Options > Regions >
-Automatically pick the region with the least ping ( )
-Country (X) <--- this one
-Country 2 ( )
This will give you more stability and solve most lag / bad connection cases.
