The Current eval script is
Phase: Traits
Priority 1000
Index 1

Script:

doneif (parent.tagis[Helper.EqpOff] = 0 )
#traitmodify[defAC,trtShield,1,""]

Timing: Before scripts: Derived trtFinal

Unless Shields have a built in functionality to add to Reflex defenses, there's nothing there in the code to do that. I'd have to go look at what things that do add to Reflex (I haven't done anything with the 4e files in like a year now), but I expect you'll need to do whatever they do.

Modify the Eval script to

doneif (parent.tagis[Helper.EqpOff] = 0 )
#traitmodify[defRef,trtShield,1,""]
#traitmodify[defAC,trtShield,1,""]

Do note that you will need to fix it on all the Rhythm Blade entries from +1 to +6, and that the description of the weapon does not indicate that the AC & Reflex bonuses go up with the weapon level, so that's an error in the existing entries.

That did it :) great work Charlieluce
