Tentacle

A Spell that calls forth a tentacle from the wand, reaching out a short distance doing damage, then retreating back to the casting point. It will grab loose items like corpses, gold or even spell projectiles, and pull them back towards you. It is not affected by Homing and will always fire in a straight line.

It will not damage crates or barrels by itself.

Also has a timer variant.

Tips

 * As the tentacle will pull all (most?) projectiles, it presents a very real risk when using it. For example if a grenadier shoots at the extended tentacle, the retracting tentacle will pull the grenade back into you, so be careful.
 * Casting a tentacle with the Matter Eater modifier will localise the terrain-destroying effect on the casting position for the duration of the effect, allowing the player to tunnel through the ground like a worm.
 * Speed Up and Light Shot can make the tentacle stretch insanely far, making the Freeze Charge combo powerful at incredible range. Combining both at the same time allows the tentacle to ignore obstacles, though the freeze instant kill becomes unreliable then.
 * Plasma Beam Orbit will damage enemies but not the player.

Trivia
It is possible to make the projectile-pulling effects of the Tentacle With Timer to work for you by flinging a spell in a different direction, as shown in this Video. While a fun stunt, the value of the move in combat is debatable.
