Astronomer Class Definitive Edition

The Astronomer is an intelligence-based class.

This class give you access to the new schools of magic : Sun Magic and Moon Magic. Each of these schools offer damage skills and support skills. The great part behind these two magic is that you can combine the Sun magic and the Moon magic to create Eclipse magic. This class is not easy to master and can sometimes be confusing. Only a real astronomer can master all the celestials spells.

Quick Class Build

The Damage Mage : The Astronomer is mainly play as a dps class with great debuff. You have a lot of option for damage and debuff, because of the combining mechanic. Skills such as : Cosmic Strike combine with Sun Essence give you the skill Penumbra Beam, this skill deals good damage in a marked zone. But you can also just empower any Moon or Sun skills with it own essence, such as : Sun Eruption combine with Sun Essence allow you to melt a percentage of the enemy's physical armor and reduce it physical and fire resistance. This class also offer some support skills like : Stellar Shield, Lunar Blessing, Luna's Light and more.

How to build this class : For the attributes max Intelligence and Wits, you also want some point in Memory. I suggest to max out, as fast as you can, Hydrosophist and Pyrokinetic for the abilities. The Talent Savage Sortilege is a most have for increase damage late game. This class is also best suited with a melee ally or an mage that control the battlefield with good displacement tools.

The astronomer class add 29 new skills:

Lots of skills and pretty effects, feels a little fiddly to play though.

Yeah, I definitely see Star Storm, Freezing Field, Eclipse, Lightning Strike, Mana Shield, LOL

If it feels broken, that's probably because the vase in question is there for testing, not regular gameplay. You're supposed to buy the books from the merchant placed nearby.

This is so cool, I wish it could be integrated into the world more seamlessly to feel like a vanilla feature though, being able to just get the whole collection of tombs from an urn on the beach feels kind of broken.

I'm experiencing problems where none of the NPCs mentioned in any of your class mods show up to sell the listed spells when I start a new game. Has anyone else had this problem? And how do I fix it?

I like this mod a lot. I keep coming back to it in our multiplayer game. I'm just wondering how people are playing the class. Do you pump up pyro and hydro all the way to 10 each? how do you deal with physical armor on enemies? Do you always try to use certain spells to get the eclipse spells? Are there certain "rotations" you use first? Just curious. A few pyro skills felt like they didn't scale well, even with 10 pyro and 30+ intelligence. Damage was barely over 100 or slightly under. Can you play this class along with the Chronomancer class? That way you'd have both physical and magical damage covered BUT.... will the stats be spread thin? Pyro, Hydro, Necro and Warfare!! Thoughts!
