Concentrated Explosion

Concentrated Explosion is a spell that drastically lowers the radius of an explosive projectile while increasing its damage.

Tips

Concentrated Explosion reduces explosion radius by 30 when the projectile is cast, but adds an extra entity that changes the explosion radius again after one frame to be 5. If the projectile has one frame lifetime, only -30 radius change happens.
Due to this, the explosive will do no damage whatsoever unless it detonates inside an enemy hitbox, which makes this spell limited in practical uses.
When stacking Explosion damage on endgame wands, limiting the explosion radius while increasing damage is very desirable to keep Noita running.
This can be used to turn a nuke into a large radius Earthquake projectile.
Unlike Remove Explosion, it can reduce the explosiveness of Explosive Boxes, Unstable Crystals, Propane Tanks, Lightning Bolts, or Thunder Charges, making them relatively safer to cast.
