5%-15% in the pictures. I'm sure this might increase exponentially buuuuuuuuuuuuuuuuuuuuut...Clearing an existing walk has a chance of causing each of the walks—from one to fifteen—to become a surge walk.
I guess my question is why, not only is it random but there's 2 forms of randomness? Procs and Clears. One person enters, wipes, warps and then it's gone? You can't get the necessary people for an hour and it's gone?
Not only that, but it's random with NO visual indicators of whether something has changed. I'm sure it's easy enough to check, but it's a bit tedious after clear to have to go to a spire, check, then go to the correct one.
