Just start the Trinity char and do the tutorial.

First part of the Tutorial (killing of your first few mobs) is a bit tiresome, though - but thereafter you'll get an explanation about the weapons and armors.

This tutorial takes abt 20 minutes. After these 20 minutes, you'll be level 51 with lvl 6 SES armour and weapon included. Be advised that maintenance costs of these Trinity chars is (very) high.
