I was playing around with Tron and Rapunzel’s abilities to give the frontmost ally starting stacks of Hardy.
Tron’s green gives 2 stacks.
Rapunzel’s red gives 6 stacks.
When Tron and Rapunzel are both in battle, only one of their skills proc. In this example, only Rapunzel’s Hardy stacks are applied. We should be seeing 8 stacks here.
