Sometimes when using XMP Bursters you see that you have scored a "critical" hit on an enemy resonator. Does anyone know the likelihood of a critical hit taking place and how much more damage (ie. is it double a normal hit) it causes?
It looks like it means that your XMP make double damages.
Critical just means double damage. So for example a L1 burster at zero distance will do 300 damage rather than 150. That's what I have been observing. This doubling is affected by distance. As the damage is relative to resonator energy/level and it's rounded up to a minimum of 1% (even if it's 0.2% for example when hiting a high level resonator with a level 1 burster) you get those critical 1% hits.
