The character of Raiden did not arrive alone in this 2.1 update and it is a renowned archer who also enters Genshin Impact. Sara can join your forces and help your team on your journey through the world of Teyvat. However, you should not expect the latter to be your main source of damage since it is rather support oriented and it will bring buffs or energy to its allies.
If you want to play Sara, you will not have to dwell on her basic attacks, but rather on her skill and her burst which will boost the attack of your character arriving on the field. Her second passive will also allow you to act as a mini battery for your other characters, restoring 1.2 energy to them for every 100% energy recharge Sara has. Be careful, this effect only works if Tengu Juurai: Ambush hits an enemy and it only applies every 3 seconds.
The Tengu Juurai: Ambush is summoned via its elemental skill when you follow its activation with a fully charged shot. Fortunately, his first passive reduces the duration of the charge in aiming mode by 60%. So of course, we could think of playing Aimed Shot with a Rusty Bow for example, but as said above, Sara is not there for the DPS, but to boost your team. Of course, just because it's a support doesn't mean it can't do damage, but that's not its primary role. However, his burst will do some pretty decent damage.
Now let's get back to the character's problems, because she has a few flaws , notably the fact that the boost she grants via her burst or her skill does not stack and only the last one active will remain. Sara's other issue is that she needs to be at least C2 to make her truly viable and C6 if you want to play her as an Electro support to her full potential.
Gameplay : Sara is played as a swapper that you will have to bring back each time to launch her E or her burst before switching back to your DPS so that the latter gets the attack bonus.

Of course, these characters are only examples and do not constitute all the playable characters with Sara but just a small representation of what you can do. Your imagination will allow you to create your own teams and test according to your preferences.
