How exactly do Frog Squad passives work? Lets take Nagato and Yahiko. When Yahiko uses his chase skill and Nagato's passive (+NIN because of chase) is triggered, does it also trigger Yahiko's passive (+NIN when other frog ninja triggers passive)? I assume the latter doesn't trigger from itself or it would be an infinite loop? Does it trigger from any passive of all frog ninjas including himself? Is the bonus multiplicative: NIN * 8% * 8% * .... or additive NIN * (100% + 8% + 8% + ....)?
