When the new world comes out after Wintertusk there should be new astral spells. Here are some of my ideas.
Sun Spells: Titan +275 damage to one spell. it looks like a giant golden fist with gems carved into it. Elf Bane +30% to one spell. It looks like a golden bow with a diamond pointed arrow with gems carved into the arrow and bow. those are the only two i could think of
Moon: A raven elder who is death. a valkrie that is life. a crab warrior that is balance. and a wolf that is myth. astraus that is storm. the moon god that is ice. and mithraya that is fire.
Star: Idk the name, but an aura thats is +15% health. thats all i could think of for that one.
