Listed weapon projectiles gain up to 3 bounces and might pass through enemies and walls.
Iron Blue Will (VII) is one of the Arcanas in Vampire Survivors. It is unlocked by reaching Level 50 with Gennaro.
When this Arcana is active, the following weapons' projectiles gain up to three bounces (triggers by hitting an enemy, mostly), the ability to pass through enemies and ignore walls:
Knife and
Thousand Edge
Axe and
Death Spiral (Death Spiral +1 bounces off from screen)
Phiera Der Tuphello and
Eight The Sparrow
Carréllo (+3 bounces off from screen)- The arrow projectile of
Flash Arrow
and
Millionaire
(+3 bounces off from screen) - Drone projectiles of
Prototype A
,
Prototype B
and
Prototype C
(+1 bounce)
Javelin
and
Long Inus 
Iron Ball
and
Wrecking Ball 
Curved Knife
and
Bwaka Knife 
Shuriken
and
Yagyu Shuriken 
Instead of bouncing on enemies 3 times before using up their own pierce like other weapons, Death Spiral bounces off the edges of the screen once; Flash Arrow and Millionaire 3 times; and Carréllo 3 more times. They already have (near) infinite pierce and benefits more from staying on screen longer.
The drones' projectiles of Prototype A/B/C gains +1 bounce instead of 3, while their main weapon doesn't get benefit.
John Morris
will automatically acquire this Arcana at level 10.
Trivia[]
- The name of this Arcana is a reference to the song "Iron Blue Intention", which is the theme song of Stage 4 - The Munitions Factory from Castlevania: Bloodlines.
- Iron Blue Will is very similar to Waltz of Pearls with how both Arcanas give weapons extra bounces, but the two Arcanas differ mainly by applying to different weapon sets.
- Carréllo is affected by both Arcanas.
