Not long after I got to Age 2, I decided I needed to update Astral Sorcery to fix issue #3874 (being invincible is no fun). Having never played through AS I didn't realize at the time that this would introduce an entirely new perk system which Sevtech was not balanced against. With the new perks it is possible (via Vicio) to get creative flight in Age 2, completely annihilating the balancing around other modes of travel available in other mods (such as viescraft).

It seems really odd to me that the Iridescent Altar is even available in age 2, given that the Tier 4 Blood Altar is locked out (unless I'm just an idiot). I propose locking out mantles of the stars or the final tier AS altar until sometime after Age 2.

Note for future: AS allows limiting of max level based on stage. Use this to gate when flight becomes available?

Oh crap. I just followed this path and now have creative flight in age 2... I thought it was crazy that it was available, but maybe it was left in as a hidden treat to find? I guess not! I'll just go hide my Mantle away... When are we supposed to have creative flight, if at all? That perk tree in Astral Sorcery is amazing...

Edit: Are we even supposed to be able to get the Mantle/Elytra-like flight so early?
