Dragon breath upgrades

I remember seeing that giving the dragon a ranged attack was planned and seeing the recent steam news it seems like it’s confirmed. Are the breath attacks purely visual or will there be changes to how the roar works?

If so I’m wondering if the fire and ice breath upgrades are used to grant the ranged attacks or if the dragon has a default breath that is used when neither is equipped.

The fire effects are just visual. All upgrades are just visual changes, no gameplay changes are made with upgrades.
