Asterism Arcanum | Addon for Iron's Spells and Spellbooks

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.

Spells

• Astral Echo - Teleport Spell which can be reversed if the ball of light is counterspelled in time.
• Brightburst - A spell which launches away and damages mobs that are close to you.
• Celestial Tether - This spell locks you in place (even mid-air!) And nullifies incoming damage until it breaks or you end the spell.
• Star Swarm - A spell which launches barrages of projectiles towards where the caster aims.
• Summon Lunar Moth - This spell summons a large Lunar Moth, which can be ridden and will attempt to protect the caster.
• Starfire - This spell lobs a small ball of light towards where the caster aims, piercing and richocheting through enemies.
• Starcutter - A spell that creates a ball of light that very quickly explodes, dealing damage.
• Luminous Beam - This spell creates a long skinny beam of light which damages all enemies it hits.
• Piercing Light - A spell that creates dozens of small projectiles around the caster, which may hit nearby mobs.
• Silvery Barbs - This spell can be used to protect pets, summons, and allies that are about to take damage.
• Astral Gateway - This spell is not meant to be craftable, I am working on a patch for some things players have noticed, meaning very soon I will release an update removing this spell's ability to be crafted.

"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.

Spells:

• Starfire (old) -> Starfire (new) (The spell may or may not stay functional when updating)
• Dark Flow -> Brightburst
• Luminous Ray -> Luminous Beam
• Moonbeam -> Astral Echo
• Night Vision -> Summon Lunar Moth (There is no direct replacement for Night Vision at the moment)
• Star Swarm (old) -> Star Swarm (new) (This is not the same spell, but it is comparatively effective)
• Constellation -> Star Cutter (This spell is similar, but is far more balanced)

Items:

• Liquid Luminance -> Dragonfly Wings
• Astral Armor (old) -> Astral Armor (new)
• Celestial Tome -> Astrolabe

 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!

• Astral Sea Dimension - A dimension similar to the Pocket Dimension, but traversible and with new features and mechanics inside. This dimension will be accessed through an item called the Stellar Talisman.
• Sheath Curio - I am not sure what this item will do yet, it may provide passive effects like night vision.
• More spells - I have lots of ideas, but many will not survive the testing phase, so stay tuned!
• A new boss - this is pretty far away, but it will be coming eventually!
• Mod Compat - I wanted to publish this version before working on any compat, because I want to be able to have a neat and tidy set of files to work with when I do start working on compat!
