Crystal Tracker

Arcane Lift. Anything the Crystal Tracker holds that is their size or smaller does not count towards their carrying capacity while flying. (Within reason)

Flyby. When flying, the Crystal Tracker disengages from enemies upon leaving their melee range as a free action. 

Piercing Grip. When making a Talon Swipe while in flight the Crystal Tracker can choose to deal an extra 2d4 piercing damage and force a grapple contest using the damage rolled as a bonus to the roll. (Letting go of this grapple is a free action but can be contested by the creature grappled, the damage bonus will no longer apply.)

Golden Spheres. The Tracker has three types of magical weapons built into their wings that recharge on a long rest or with an Artificer's Infusion. The effects have a DC of 16. 

Acid Bomb. This Golden Sphere finds it's way into the Trackers talons where it can lob the arcane explosive up to 40ft, dealing 6d8 Acid Damage to creatures within a 30ft sphere also beginning to eat through nonmagical matter within this space. 

Gravity Bomb. This Golden Sphere drops like a rock from the wing as soon as it is released, hitting the ground below the Crystal Tracker. A 30ft sphere is now considered dense gravity halfing movement speed, giving disadvantage to weapon attacks, strength saving throws, and dexterity saving throws. 

Lightning Tag. This Golden Sphere can be thrown up to 60ft at a single target. The Crystal Tracker has a +5 to hit and if it does this lightning tag will deal 6d10 lightning damage to that target or half as much if they succeed on a constitution saving throw as the lightning jumps to the next closest enemy. If an ally chooses to allow the chain to continue through them they will automatically succeed on the saving throw, taking half damage. 

Talon Swipe. Melee Attack: +5 to hit, reach 5ft., one target. Hit: (1d4+3) slashing damage.
