Speaking technically, we can go even further. If you smash Everlasting corrosion and the funny coin together, it has the potential for 18 tremor bursts, instead of awakening's 12~16 maximum bursts (I don't remember whether or not the first coin has the tremor burst on UT4) To fix the Hong Lu reverb problem, we'll need Yurolu and 31 Tremor Count on self, and 2 S3 on the ready.
Also why even have Warp Ryoshu there? just slap on Molar Outis with her passive up and get another 3 bursts (potentially 9) per turn and an extra 20 sloth damage per burst. Common tremor W btw
