Vampire Survivors: How to Get the New Secret Character Gyorunton (Easiest Method)

Leda can be unlocked by: Travelling downward in Gallo Tower, until the screen starts to turn black. You’ll find Leda among the usual mobs, keep your eyes peeled it’s easy to run past him.
Simply defeat Leda here and it will unlock the character.

This Arcana can be unlocked by: Defeating the final boss of Cappella Magna.

This Arcana blocks the ability to level up the character and turns XP gems into guided missiles that explode on impact.

This level unlocks by: unlocking Hyper Mode for all 5 normal stages

The easiest, no sweat method.

Game Killer will block XP gain which means that the enemies will also stay locked to the lowest HP possible, as they won’t level up either. The secondary effect of this Arcana will turn XP gems into missiles that will deal additional damage.

Leda’s starting weapon “Holy Wand” is easy mode against tier 1 goons.

Mini bosses will take some maneuvering to avoid damage.

Completion will take around 15 minutes.
