Gives +13 max supply and +5 starting supply.

Not an obvious punch up in power.

Makes initial time to make a bigger army cheaper, given an extra five supply of units.

And stacking these buffs is kind of an obvious end game bonus.

Both Prefect Aster and Galavax can hit max supply pretty easily given there powers create units that take up supply, so could be beneficial for armies that need large groups to split up to hold objectives.

Perhaps an uneducated opinion, but I would skip this if focusing on Vynthra unless a good neutral power comes out that takes supply. Because your not reasonably hitting supply cap in harder difficulties in solo co-op.
