Anyone know how the guards (lightning, acid, good, etc.) work?

Just wondering how these guards work.....do they stack if you get the same one all three tiers (minor good guard, lesser good guard, greater good guard)? Or would it make sense to create a different guard (acid, lightning, good) for each tier?

They might stack.

The acid and the acid burst on the acid weapon my buddy made stack, meaning he gets +1d6 for acid, and +1d6 for acid burst, and +burst acid if he crits.
