If you succeeded in obtaining Hu Tao then congratulations, but now you are faced with a problem, you do not have a weapon for her, do not worry and read the guide below.
First Free to Play Weapon for Hu Tao
The First and easiest weapon you can get for Hu Tao until you get a better Upgrade is Prototype Starglitter, This weapon will provide you with Energy Recharge which is a decent stat to have on Hu Tao but not the greatest, but it will allow you to get your Elemental and Burst Skill faster, If you get this weapon you do not have to worry about putting Energy Recharge sub stats on your Artifacts and instead focus on Crit Rate nd Crit Damage.

Once you have better options like Dragon’s Bane, you can switch to it instead of the First Weapon recommended, as for the Shop weapon, it is a very good option already and you do not need to change it if you do not want to.
