About "nul" character in Chinese version

I am a Chinese player and I’ve copied lots of macros but I have the followting issue:

GSE of Chinese version cannot recognize the skills’ name and grammar in English. Like “Bloodthirst” should be translated as “嗜血” . So I wanna know what in “NUL” in Chinese
For instance, /castsequence reset=combat 破甲攻击, nul ←It doesn’t work.

Hello MyWifeKotori,

nul usually represents a castsequence line that will only run once per combat session.
