Alain Castillion

The Muted Mercenary. Alain cannot speak physically or through magical means. Alain may make one additional action on his turn once per short or long rest. Being within 5 feet of a hostile creature doesn't impose disadvantage on his ranged attack rolls. Alain ignores half cover and three-quarters cover. Alain can't be surprised while he is conscious. Creatures don't gain advantage on attack rolls against him as a result of being hidden.

Margu'ul's Curse. Dragon's Maw is a cursed crossbow which possesses the soul of Margu'ul, an Ancient Red Dragon who reveled in the screams of lesser beings. After her defeat, her soul was captured and imprisoned in the crossbow that slayed her. The weapon was enchanted with the power of a dragon, which was used as a catalyst for the engineering marvels of the dwarves, but the Margu'ul's soul never stopped hungering for the voice of her victims. Dragon's Maw claims the voice of whoever attunes to the weapon, and ceases to function if it is not being used by the person who is attuned to the weapon, returning to the user one way or another in 1d4 days.  

Serpent Bolts. Specially fabricated bolts made from schematics known only to Alain and lost to history, crafted by Oxwell's weaponsmiths, these bolts come in magazines of 20 for each variety. Alain may choose a type of bolt magazine to load into the crossbow as an action and may eject a magazine as a bonus action. 

• Rending Bolts: Deals 1d6 slashing damage, or 2d6 slashing damage if the target is wearing light armor or less. Damage dealt by the attack is doubled if the target is unarmored. 
• Bonebreaker Bolts: Deals 1d8 bludgeoning damage. If the target is wearing metal armor, the armor class of the target is reduced by 2 to a minimum of 10. If the target is using a shield, the shield shatters and is destroyed. If the target has natural armor and is not resistant or immune to bludgeoning damage, their armor class is reduced by 1 for 1d4 hours. 
• Earthbind Bolts: The target must make a DC 18 dexterity saving throw or become restrained by the net that is deployed by the bolt. The target may make a DC 18 strength saving throw to escape the net once it is trapped by it. 
• Tethering Bolts: A bolt fires in a line 400 ft. long and 1 ft. wide to the target. The target must make a DC 16 strength saving throw or be pinned to a creature, object or terrain piece that is within the line and is a maximum of 10 ft. away from the target. If tethered, the target is pulled toward the other target may not move further than 5 ft. away from it. Either target may make a DC 17 strength saving throw to remove the tether. The density of the bolt can crack or break full cover if it did not hit a creature, reducing it to three-quarters cover, half cover or destroy the cover at the DM's discretion.

Multiattack. Alain makes three attacks with Dragon's Tongue or Dragon's Maw or one attack with Dragon's Breath.

Dragon's Tongue. Melee Weapon Attack: +9 to hit, reach 5 ft., one target. Hit: 9 (1d6 + 5) piercing damage. The target is grappled and can attempt to escape with a DC 14 Strength Saving Throw.

Dragon's Maw. Ranged Weapon Attack: +11 to hit, range 400 ft., one target. Hit: 11 (1d10 + 5) piercing damage plus the effect of the bolt chosen by Alain.

Dragon's Breath. Ranged Weapon Attack: +11 to hit, range 5ft., one target. Hit: 33 (5d10 + 5). May only be used on a target grappled by Dragon's Tongue. The target is pushed back 15 ft. away and is knocked prone.  Alain must reload Dragon's Breath as an action. 

Sharp Sight. Using his reaction, Alain may use a search action as a result of a creature attempting to hide from him while they were in his line of sight during his turn. Alain has advantage for the search action.
