- Under our OSI casting,you can immediately cast next spell after the previous one being disturbed and dont worry about overcast.The next spell will give you target cursor as usual.
- The overcast silent fizzle will occur when you cast a spell as soon as the last one is disturbed.
I repeated the same test on Demise OSI casting,there are no overcast issue after spell disturbance.
A side note:FCR takes effect too when overcast happens.You can verify it in the video.
