Hexwright

You don't aim the magic. You write it.
Every mage starts with one sad little spell. Every level-up stops the fight and hands you a glyph, a piece of magic, and you snap it into the spell you're already casting. Fire. Frost. Poison. Blood. Make it orbit, bounce, split into a volley, come back like a boomerang. A few levels later your fireball has turned into something nobody planned, including me.
Build the spell that breaks the game
Arrows that make the whole horde bleed. A poison aura that turns into a walking plague. Ice spears that circle you like a frozen crown and throw themselves at anything that gets close. Every run deals you different glyphs, so every run grows a different monster of a spell. And yes, some of them are broken. That's the point.
Hold the night
After dark the forest comes for you, more of it every night. Then something huge crawls out of the ground to see what all the noise is about.
Gear up at dawn
Survive until first light and the shop opens. Buy rings, robes, boots and stranger things, then cram them into your bag like a real adventurer: drag, rotate, make it fit. Two of the same item fuse into a stronger one, and some gear doesn't just boost your stats, it changes your spells.
Come back stronger
Carry what you earned back to your ruined floating island and rebuild it. Then open the Glyph Book, a skill tree of magic. Every branch you unlock adds new elements, forms and spell effects to future runs, so the more you play, the stranger your spells get.
