Lifetime Modifier Spells
Spell modifiers that adjust the lifetime of the affected projectiles.

A spell modifier that causes a projectile to have a shorter period to live before timing out and dissipating. This can cause a projectile to not being able to reach the target you're aiming at, but reduces cast delay to compensate which causes the next spell to fire faster.

Tips

• Reduced projectile lifetime is often a detriment, so you'll essentially be buying reduced cast delay for 10 mana and less range.
• As cast times are ignored when spells are fired by a Trigger, using it as part of a delivered spell package in this way is not a good idea if rapid fire is what you're after.
• Can be used to make timed spells like Death Cross or Bomb explode faster. Useful when delivering them with a Trigger spell.

Trivia

It is difficult, but possible, to utilize an exploit in the gamecode to make this modifier cause a projectile to never expire. By knowing the lifetime value(s) of a projectile you can use the modifier to change the lifetime value of the projectile to -1 frame (lifetime in the code is measured in frames) and cause the projectile to never despawn, as seen in this youtube video. This phenomenon was eventually made into a feature and now, when you cause it for the first time in a run, you get the message:
the gods are very impressed with you

There is also a Steam achievement for it.
