Hi! Shrike recently hit tier 12, I'm looking to upgrade their set a little. I just want two items that preferably heal and do what I'm doing now, but are more powerful. I'm currently using Bludgeon of Mass Extinction and Malignant Rift Staff with Terra Focujin. I have 175 million sP. I have no idea what I'm doing. Any help would be greatly appreciated! Thanks! <3

Have you looked into the guides? This Planning for the Endgame (T10+ Guide) spells it out really well. This https://subeta.net/forums.php/read/887189/Planning-for-the-Endgame-T10-Guide

Once you reach T12 you don't really have 1 "set" You need to adapt your weapons to the opponent you are facing. You are at the point where you can either A Beat any enemy that isnt impossible with anything or B You need to use the right gear vs the opponent you are facing.
