Astronomical! is an achievement that requires the player to craft at least 56 astral runes simultaneously, without using pouches or familiars.
Requires a full inventory (28 pieces) of pure essence. Boosts may be used, but players cannot use pouches or familiars. You cannot wear the Ethereal outfit.
Another strategy is to use the wicked hood charged with an omni-talisman or an omni-tiara. Players can use it teleport to any altar and withdraw a full inventory of pure essence. Players can simply boost at any convenient bank, and then teleport.
