Embolden + Sheltered Ring Works

The question of these stacking was brought up a while back and I never found any testing so I figured I'd stop wondering and actually test it.

Base DEF: 400
Protect IV: 520
Sheltered Ring + Protect IV: 528
Embolden + Protect IV: 580
Embolden + Sheltered Ring + Protect IV: 588
Sheltered Ring + Protectra V: 585
Embolden + Sheltered Ring + Protectra V: 672

Assuming that holds true for Shell as well then we should be able to get a Shell V of 98/256 (38.2%) or Shellra V max 117/256 (45.7%)

It's a shame that embolden doesn't double the effect from sheltered ring though >.>
