IMPORTANT INFORMATION FOR UPDATING VERSIONS
The previous version of this addon will NOT properly update to this version. If you are intending to update your world, please MAKE A BACKUP, and keep in mind that you will need to manually replace items (including scrolls). The reason why this is is the case is listed in the FAQ below. I have also created a guide (below) to suggest potential item replacements if you do plan to update from the older version of this addon.
Future updates will not have an issue with discontinuity
Asterism Arcanum is an addon for Iron's Spells n' Spellbooks, which introduces a new school of magic, a new structure, new blocks, and 3 new mobs. The new school of magic is the Astral School, which is focused on caster longevity by means of evading damage and maintaining distance from your enemies. In simpler terms, this school is designed for people who like to run away!
The new structure that comes with this addon is called the Astral Observatory, which generates on mountains and is the home of the Astromancer mage npc. Unfortunately, as the observatory has been partially abandoned, hostile mobs have made nests in the structure and consequentially will now attack any interlopers.
These new hostile mobs are Dragonflies, which when killed drop their wings. These wings can be used to craft astral spells, or to craft two new block sets-- the Lumine and Umbral Lumine blocks. These blocks can also be found in the Astral Observatory.
Finally, the mod also introduces the Lunar Moth, which is a neutral creature that can rarely spawn on steep mountain tops. If you struggle to find one of these friendly critters, you may also opt to gather their eggs, which sniffers dig out of the ground! These eggs can be thrown to create new moths, or to deal effects to enemies. There is also the option to summon your own Lunar Moth as a mount using one of the spells in the Astral School.

FAQ:
"Why can't we update directly between this version and the previous one?"
Over the past few months, I have been putting in a lot of work to make the addon much more functional and visually appealing. Unfortunately, this also means that most of the code from the previous version no longer exists in the new version, so Minecraft doesn't know what to do!
"I love 1.20.1!! Port this to 1.20.1!!"
If you know someone who is willing to do the work, they can reach out to me for permission. I will not be doing this myself because I am one person and I am providing this content as a courtesy (meaning I get to choose how much effort I put in :D) I will not respond to any comments about this unless they are from people interested in doing the porting themselves.
"Why are there more dependencies now?"
I have included Aces Spell Utils because it is required for how the Astromancer is configured, as well as some astral spells and items. Azurelib is required to render the celestial staff correctly. ExpandAbility is not used for content accessible in Survival, but in the next update, I will finish the content currently locked to creative mode. I have chosen to include the unfinished content for those who want to play around with it in creative mode!
"I don't know how to craft these things!"
The recipes are unlockable in the recipebook, and I would suggest using JEI if you do not have it installed. Dragonfly Wings are the new resource for crafting astral spells and astral runes.
"There's no spellbook?"
The Astrolabe item functions as a spellbook.
"Where did the old items (scrolls, armor, etc.) go?"
They have been removed, I will gradually be introducing similar content over the next few updates. See the replacement guide if you want to see what I have changed into new content.

These are what I would like to achieve, not necessarily in chronological order. I may also end up adding things that are not on this list or abandoning ideas that are on this list!
