So.. With Hades V1.0 Launch, there is a new keepsake you can get by giving nectar to Hades, the keepsake gives you the Hades Call from the beginning of the run and grants you a 10% starting god gauge.
With his call you turn kinda invisible and also you get some bonus damage.

Good thing daddy's aid only gave Z invisibility. Would be awkward to hit yourself with your own attack….
Hades confrontational tone even when faced with his own power is hilarious
I love the "WHAT!" when you do greater call
