Luminous Drill

This spell fires a short-ranged, high-penetration beam of green light. While effective in close range, Luminous Drill is also a very powerful digging spell and can cut through any material in the game, just like the Black Hole.

Also has a timer variant which has a mana drain of 30 instead of 10.

Tips

 * Stacking multiple instances of Luminous Drill with Timer can create a very long stack of the spell which acts mostly like a single long Drill, assuming they are placed in a wand with enough mana to cast them all. This can be very useful for attacking enemies through barriers, such as in the tight quarters of the Hiisi Base
 * Although the mana drain stat appears low, the spell has a negative Recharge Time (just like the Chainsaw and Digging Bolt spells) and so can quickly burn through a wand's mana reserves.
 * Using the Increase Mana projectile modifier on a wand with a low cast delay and recharge time, it is possible to create a permanent 'lightsaber' effect which can slice through most terrain like butter.
 * This spell ignores projectile shields and is generally very effective against all enemies.
 * The timer variant, while mana intensive, can be used to cast other spells through even steel walls. Additionally, since cast delay modifiers on the triggered spell is ignored, you can make any other spell fire just as fast as the Luminous Drill can.
 * When used with the Increase Duration modifier the Luminous Drill will fire like a Magic Arrow, making this spell long-ranged. You can also achieve this with the bouncing spells perk, which increases spell durations as one of its effects. It can also be accomplished with the Ping-Pong Path modifier, which costs 0 mana.
 * It reaches the maximum speed of a projectile and its distance cannot be significantly increased by modifiers that affect projectile speed.

Trivia

 * Often referred to as "laser sword" or "lightsaber" in the Noita community
