Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
Cannot be Normal Summoned/Set. Must be Special Summoned with the effect of a "Triamid" card, and cannot be Special Summoned by other ways. If a face-up "Triamid" card(s) you control, except "Triamid Sphinx", is destroyed by battle or card effect: You can Special Summon this card from your hand. While you control another "Triamid" card, this card gains 500 ATK and DEF for each Field Spell Card with a different name in your Graveyard, also monsters your opponent controls cannot attack, except to attack "Triamid Sphinx".
