I think it would be a better idea to see it like this:

The shield must be bought from that merchant guy. Most likely around 4000 - 5000 gold (whatever the currency is).

The shield loses 8 energy points as it gets hit. If it hits 0, then you can not use it again until it goes back up to 100.

The sword won't be any weaker than when you didn't have a shield. The shield will be set to D and the sword to S (and vice-versa). The shield button must be hit to use it and block an attack from a plasma weapon.

Like I said, I'll be glad to add in the shield to my upcoming plasma sabre ganis. If Stefan approves, we'll discuss which param/attribute it should be set to and how it will be made.
