1) Deflectshield (which is the syntax per the helpfile) doesn't work. If I type it in, it gives me "Huh?".
2) For some strange reason, deflect shield sometimes doesn't trigger. It happens periodically. See below.
*snip log*

You are correct in that it was about the shield being energy. That issue also extended to other materials.

So I fixed that, and did some stuff.

1) Syntax in helpfile fixed to just 'deflect'.
2) Material issues fixed

There now will always be echoes.
I also added in a few special things: When you deflect an energy shield with an energy mace, a water shield with a water mace. I didn't go any deeper than that since I was mainly filling in missing variables.

But maybe at some point (perhaps a Santa Umishuli wish) I'll fill out all the material match-ups.

Short version - it's fixed and echoes should always happen now.
