Each Void Seed is now worth 480,000 rupees

For those that didnt notice they changed the conversion rate for void leaves in the treasure trade

The new rate means that 80 leaves converts to 480,000 rupees. Each void seed converts to 80 leaves.

This means that Avenue of fortune is almost strictly worse than 2x void battles because between the seed drops and natural void leaf drops on a 2x void battle will equal or exceed Avenue of fortune runs for rupees.

There is the added factor of RNG involved here on the seed drop rates but at 2 augments per run and the void hearts, you're going to be getting something you need either way
