Hi, what is the good item to equip ashee? only much berseker or have other?,

There is never a good set of equipment.
You should always choose your items according to your enemy.

Agreeing with CR4ATI0N's comment, but if you're new to the game for an adc you'll generally want the Bloodthirster or Blade of the ruined king for sustenance through life steal and a crit item like infinity edge. you can look on mobafire for in depth guides by high rank players with builds for all kinds of situations
