Should I level a pain enhancer? POJ

The top monk uses POJ and pain enhancer, Taeguk, and trapped. I’ve been using stricken this whole time. I’m assuming the POJ set buffs Pain Enhancer for trash damage.

Without stricken I will rely on angels to do the boss kill right? I haven’t checked non season to see what they are using. I’m not good at timing out the angels to kill the boss.

I can practice that. Or is pain enhancer like only for 150s? I’m running 126 as a solo push.

If you will not be using the standard RGK benefiting Stricken… You only use Pain enhancer if you will be utilizing the 500 kill-streak Angels bonus
