Hello Shai Mains,
With the newest update today we have access to 6 add on slots now (Finally)
Here are the Add-ons that I am gonna be running. I don't suggest getting duplicates on Shai due to our skills being on such a low Cooldowns. And the HP recovery on every single skill is gonna help you survive way easier. If you are someone who only does group spots you can replace -4% evasion and -15 DP if your partner has skills that can effectively apply them but still, Shai has a way more reliable add-on up timer. 

Happy Grinding
