Как проверить?

[LinxFree]

Че мне тут пишут что нельзя в макросе проверить наличие бафа на себе, а как тогда это делают аддоны? И как тогда наличие петов проверяют, или возможность юза спела? Это всё можно... Кто знает отпишите как проверить?

HARMFUL - Show debuffs only
HELPFUL - Show buffs only (default)
NOT_CANCELABLE - Show auras that cannot be cancelled

Возможности макросов ограничены, а аддоны работают на программном уровне, который недоступен макросам. Макросам доступно очень ограниченное количество простеньких скриптов.
Да, макросом нельзя проверить наличие бафа не только на себе, но и на каком-либо другом объекте. Запомни раз и навсегда
