In newest map DotA_Allstars_7.00e4.w3x
If Doom with Aghanim's Scepter use ulti on Magina , and Magina use 3rd spell (counter spell), Ulti will reflect on doom and will last 36 sec instead of 16
(if doom use ulti without aghanim's it will last 16 sec as it should be)
According to Doom's Aghanim's , target should be affected as long as Doom is there in 900 AOE, so shouldn't doom be affected with his own ulti until death?
Let me know if you need replay but it's obvious thing and very complicated
