Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
[ Pendulum Effect ] You cannot Special Summon monsters, except "Qli" monsters. This effect cannot be negated. All monsters your opponent controls lose 300 ATK. ---------------------------------------- [ Monster Effect ] You can Normal Summon this card without Tributing. If this card is Normal Summoned without Tributing, or is Special Summoned, its Level becomes 4 and its original ATK becomes 1800. If this card is Normal Summoned/Set, it is unaffected by activated effects from any monster whose original Level/Rank is lower than this card's current Level. If this card is Normal Summoned by Tributing a "Qli" monster(s), it can make a second attack during each Battle Phase, and if it attacks a Defense Position monster, inflict piercing battle damage to your opponent.
