Ties for Initiative

[Brazen Hussey]

This has to have been answered already, but a quick search failed to reveal.

When there is a tie for initiative, do you just re-roll? Or does anything else break the tie?

I'm learning the system with a bunch of one-on-one combats right now and so breaking the tie with adjDX would be easy. But that doesn't work so well for larger combats.

Anyway, thank you for letting me ask the noobiest of noob questions noob there.
