4 MAG of protection will stop ALL knockdowns and many knock effects. 8 MAG (2 IOs) will stop most of the rest. 12 (3 IOs) MAG will stop all but a small handful of attacks.
Acrobatics, however, cannot truly be replaced by IOs, as it's 100 MAG protection.
The City of Heroes Community is a special one and I will always look fondly on my times arguing, discussing and playing with you all. Thanks and thanks to the developers for a special experience.
I was wondering if Karma:KB protection with mag 4 was enough to replace acrobatics?
