This is the build I wanted to try when Mihoyo reveal the character. I wanted to go for 2p Gladiator + 2p Bloodstained but I still don't have a good second Gladiator artifact to put on him so I just take my best artifacts + 2p Bloodstained. With this build, going with Xingqiu and you should have 100% uptime on the Crescent Pike's buff + extra damage with Xingqiu's A and self-healing. Team comp really depend on the content you try to clear or the enemy you are facing so it's up to you.
