Spellbinder

Spellbinder is a passive item in Vampire Survivors. It is unlocked by getting the Runetracer to Level 7.
Spellbinder increases Duration by 10% per level.
Spellbinder is required for the evolution of King Bible, Unholy Vespers. It is also required for the evolution of Mille Bolle Blu, Boo Roo Boolle, in which Spellbinder must also be fully leveled.
Spellbinder can be found as a stage item in Gallo Tower, Moongolow, and Boss Rash.
==Levels==
Spellbinder has 5 levels. At max level, Spellbinder provides +50% Duration.
Level 1	"Increases duration of weapon effects by 10%."
Level 2	Effect lasts 10% longer
Level 3	Effect lasts 10% longer
Level 4	Effect lasts 10% longer
Level 5	Effect lasts 10% longer
==Tips==
*Duration is not used by many weapons, but the weapons it does benefit, benefit greatly from it. It is a great early pick for Pasqualina, Poppea, and Mortaccio, due to their starting weapons and abilities.
==Trivia==
*Spellbinder's old design is very similar to whip upgrades from Castlevania: Harmony of Dissonance, especially the bullet tip upgrade.
