[gameplay] permanent oracles on zac

i was playing an aram and i was against a teemo so naturally i bought oracles to counter his shrooms however after the effect ended i still had the effect and it did not go away. I am not sure how i achieved it but it could have been just buying it or buying it with full items while dead. i'm sorry i dont record and dont know if this can be achieved frequently but because of its nature i assumed it could. :)
