Did some calculations and was wondering if my calculations were actually correct and/or viable:
The cooldown cap seems to be at 60% which can be achieved on cataract with both cooldown flags, magnificent presence 2 and staff of renewal.
In theory it should be able for a team consisting of TB, Sed and UB to stun a single enemy with a maximum time non stunned for 3 seconds while the other 2 enemy demigods would have 1 second of using skills at lvl 10. At lvl 15 a single demigod would not be in stun for a maximum of 2 seconds while the other 2 would not be able to use any skills (assuming that all are in range of frost nova and silence). Stun immunity is 5 seconds afaik, beinning at the time the stun starts.
Favor items: sor for TB and UB, diamond pendant for Sed, both cooldown flags have been captured.
Lvl 10: Grasp and FN cooldown 6 seconds, silence 7.2 seconds
Start with Nova (2 seconds), second 3 Grasp, second 4 Silence, second 7 nova (in effect at 8), second 10 grasp, second 12 silence, second 14 nova and so on...
The targeted demigod should never be not stunned for more than 3 seconds, while the surrounding demigods should either not be stunned or silenced for more than 1 second (and not able to disrupt the next nova).
Lvl 15: Grasp, FN: 6 seconds, silence 6.45 seconds (round it up to 7)
Nova (3 seconds), second 4 grasp and silence, second 7 nova (in effect at 8, silence wears off), grasp/silence at at 11, nova at 14 (in effect at 15, silence wears off), grasp/silence at 18 and so on.
The targeted (and slowed down) enemy dg would not be stunned for a maximum of 2 seconds, while any defending dg in range of of silence and nova would not be able to use any skills at all (either novaed or silenced). Theoretically this sounds incredibly strong but Im not sure, if my calculations are right or if it is actually viable to pull something like that off (would imply that locking the cooldown flag would be extremely important for the team doing this). And enemy creeps/idols would be completely useless.
