Arc Light

This crossbow gains a +3 bonus to attack and damage rolls made with it.  Base damage done is 2d10 Piercing damage + 2d6 lightning or fire damage.  You gain the Archery fighting style while attuned to this artifact.  

Weapon Modifications:  This weapon is the product of hard work and years of tinkering.  The grappling hook and flashlight can be used any number of times, where as the Bolas, Ricochet, and Armor Piercing shot can be used a number of times equal to your proficiency modifier each.  Once used, these magically recharge on a long rest. (Ricochet Shot is a special circumstance that utilized divination based magic)  

• Grappling Hook:  This mod fires a 60 foot line of steel cable with a grappling hook shaped arrow that open into a tri fold hook.  When you successfully hook to an object, it can support up to 300 lbs and you then gain a climb speed equal to you movement speed.  As a bonus action you can flip the lever to automatically zip up the 60 feet to the arrows entrance point. 
• Bolas Shot:  You fire a three burst bolas system that requires your target to make a Dex save to initially dodge the burst, followed by a Str save if they are caught.  They may attempt to break out at the end of each of their turns.  They make the Str save with disadvantage if failing the Dex save bellow half. (Dex and Str saves are you spell saving throws)
• Ricochet Shot:  Three times per long rest, you may reroll a missed shot with this weapon.
• Armor Piercing Arrows:  Your shots ignore cover advantages and deal double damage to structures as if under siege weaponry.
• Flash Light:  You may activate a bright light that shines in either a beam (60 ft) or cone (30 ft).  You may activate a strobe like effect to temporarily blind/disorient someone for one turn. (Con Save to shake off blindness)
• Silver Arrows:  You bypass lycanthropic and other creatures with aversions to silver. 

Kinetic Amplifier:  A number of times equal to your proficiency modifier, you may perform a ranged variation of the Eldritch Smite.  Damage dealt is 6d8 force damage and recharges on a short/long rest.  You score critical hits on 18-20 with this weapon.

Anarchy:  A number of times equal to your proficiency modifier, you can flip a switch which converts this cross bow into firing electrically charged stakes that act as conduits for dangerous arcs of pure electricity.  You may fire a shot at your target and an object to tether the current of lightning.  A tethered target takes 10d6 lightning damage at the start of each of your turns and is pulled 10 feet closer to each other.  If you would choose, you may fire two tethers at the target instead to force it to make a Dex save or have its movement speed reduced to 0 for the turn.

Arcane Boosted Tech:  While attuned to this artifact, you gain the following spells added to your list of spell known.  They do not count against the number known, and you may cast them each once per long rest for free before doing so again: Hunter's Mark, Pass Without A Trace, Clairvoyance, Greater Invisibility, Swift Quiver.

• 2 Major Detrimental Properties:  When you attune to this artifact, you take 4d10 psychic damage.  When you become attuned to this artifact, one of your ability scores drops by -2 at random.  A Greater Restoration Spell will cure this.
