Aura Radius
Expand your magical influence, turning localized spells into screen-clearing cataclysms.
Aura Radius is not a weapon in the traditional sense but a vital passive gemstone that fundamentally alters how magic behaves around the survivor. In the chaotic battles against endless hordes, this relic ensures that area-of-effect abilities and magical projectiles maintain their potency regardless of distance or obstruction. It serves as a cornerstone for builds relying on widespread damage, allowing spells to engulf enemies in every corner of the screen.

Lore & Background
Legends suggest these gems were once used to ward off entire armies from castle walls without the mages ever needing to leave their towers. By amplifying the 'aura' surrounding a caster or their summoned constructs, the gem allows magic to stretch further than natural laws would permit. It is said that when a survivor holds an Aura Radius, the very air around them hums with potential, turning a simple fireball into a wall of flame and a minor healing pulse into a field of restoration.
In Their Own Story
The fog over the Gallo Tower was thick, obscuring the ground where thousands of ghouls clawed their way forward. Elia, the survivor, stood alone at the center, her hands trembling not from fear but from the sheer volume of mana she had to control. She raised a small, pulsating crystal—the Aura Radius. As it glowed, the fireballs she cast did not fizzle out after ten feet; instead, they expanded into roaring spheres that consumed the front lines and reached deep into the rear ranks. The ghouls shrieked as the magic touched them simultaneously, a synchronized wave of destruction that turned the tide before Elia even took a step.
Reader's Guide
Aura Radius functions by increasing the radius of area-of-effect attacks for most weapons in your arsenal. When you collect this gemstone, it immediately expands the hitbox of spells like Fireball, Magic Wand, and Holy Water, allowing them to damage more enemies at once. To maximize its effectiveness, players should prioritize collecting multiple Aura Radius gems throughout a run. Each additional gem further increases the range, creating massive zones of destruction that can clear dense enemy packs with a single cast. This is particularly crucial for late-game survival where enemy density becomes overwhelming. While it does not have a traditional 'max level' like active weapons, its power scales linearly with the number collected. It pairs exceptionally well with evolution conditions; for instance, expanding the radius of specific projectiles can help trigger evolution requirements faster by damaging more targets simultaneously. Always prioritize this gem when playing magic-focused characters.
