Scripted weapons

http://webzoom.freewebs.com/xmuppets.../25rc3test.qst
In this quest file, I have stumbled upon two problems with scripted weapons. The 'Gohma (Laser)' enemy in particular uses a scripted weapon (lasers). Here are the problems:
1) This weapon still hurts Link while he's invincible
2) Rings and Peril Rings do not reduce damage taken from this weapon.

The relevant script isn't included in the file, so I can't check it, but I would guess that it's setting Link->HP rather than using built-in damage handling.

That's because I import the .z files for ghosted enemies to save room in the script file itself.
The relevant scripts can be found here: http://www.purezc.com/forums/index.php?showtopic=51270
