The AS Attunement Altar is very useful and unique, but the part where you have to break the relays to select patterns is less so. Selecting from the available constellations is awkward and can be particularly problematic if your pick also breaks one of the AA multiblock, especially if it is high up in the air.

How about an Improved Attunement Altar that shows you the known constellations and lets you pick which one you want to select? It could even tell you useful information such as how long until the constellation will be in the sky and when it will set.
