Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
If a Field Spell Card is face-up on the field, you can Normal Summon 1 Rock-Type monster in addition to your Normal Summon/Set. (You can only gain this effect once per turn.) Once per turn, during your opponent's turn: You can target 1 "Triamid" Field Spell Card in your Field Zone; send it to the Graveyard, and if you do, activate 1 "Triamid" Field Spell Card from your Deck with a different name (this is a Quick Effect).
