Ampestri Board v0

Mimicry. The ampestri can mimic any voice or song it has heard, albeit in a nasal falsetto.

Booooom Thud Boom Boom Thud. The ampestri can use its gills to drop the base.

Color Blasted Dust. The ampestri releases harmless spores that may glow in the air or on objects and clothings. 

Attuned Rider. (Sorry for making this hard) The ampestri board can be ridden by a practiced rider. While the ampestri board is being ridden, it shares the action economy of its rider. A rider may attune themselves to the ampestri board by practicing during a short rest with a DC 15 Athletics check. On a failed check, the rider takes [roll]1d6[/roll] face plant damage. The attunement process reduces the short rest's potential by 1 hour. The resting portion of the short rest must be at least 1 hour or the rider cannot spend Hit Die (amongst other things). 

An attuned rider may use skills less than or equal to their skill level by burning a spell slot. Riders may use skills higher than their level by passing a DC 15 + 2 (move skill level - rider’s skill level). On a failed check, the rider takes face plant damage of either the ride they are attempting to use or, if they are not attempting a new ride, the ride they are currently on.  Skills that require spell slots are also considered spells. The rider’s skill level is equal to one plus one third the sum of their Athletics bonus plus their hoverboard proficiency bonus =1 + ⅓ x (ATH + HVB). 

Hoverboard proficiency bonus can be acquired after three consecutive successful practices as described above for attunement. Hoverboard proficiency bonus can be added to any check or saving throw required by attuned rider skills.

Difficult terrain may not be traveled unless a skill or spell like smooth ride is used.

Spiked Head Butt. Melee Weapon Attack: +0 to hit, reach 5 ft., one target. Hit: 1d6 + 1 piercing damage.

Spores (1/Day). A 5-foot radius of spores extends from the ampestri. These spores can go around corners, and they have no effect on Constructs, Elementals, Plants, or Undead. Each other creature in the area must make a DC 10 Wisdom saving throw. On a failed save, the creature is incapacitated and its speed is halved, both for 1 minute. A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.

Wild Dismount. While the ampestri board is in motion the rider may attempt to dismount. For every skill level of the current ride add 5 to the DC. To dismount, roll a DC 0 + Skill DC Athletics or Acrobatics check. On a failed save, the rider takes face plant damage of the given ride.

Smooth Cruise. Burn a spell slot equal to the number of spell slots used to activate the ride. This skill remains for the duration of the current ride. If another ride skill is activated, this skill deactivates. The rider may travel on difficult terrain at the standard half speed.

Basic Trick. This skill may not be used for frightful ride or soul ripping ride. This skill allows the rider to make simple jumps, ampestri board flips, wall rides, and grinds. Roll an Athletics or Acrobatics check. If the result fails a DC 10, the rider takes face plant damage for the given ride. If the result passes a DC 15, the rider and one other get 1d6 of inspiration dice that can be used for the duration of the ride. 

Mushy Shoes. Burn a third level spell slot. The ampestri grow two inverted mushroom heads out of the top of the board that grip to the rider’s feet. For 15 minutes, the rider has advantage on face plant checks.

Wimp Ride. The rider may travel on ampestri board at one half the ampestri board’s walk speed for 60 minutes. At this quiet speed, the rider gets advantage on stealth checks against targets being tracked. If the rider or ampestri board takes damage, the rider must make a DC 5 Athletics or Strength saving throw. On a failed save, the rider takes half [roll]1d6[/roll] face plant damage.

Staggering Ride. Burn a first level spell slot. If another ride skill is casted, this skill’s duration is zero. The rider may travel on ampestri board at the ampestri board’s walk speed for 30 minutes. If the rider or ampestri board takes damage, the rider must make a DC 10 Athletics or Strength saving throw. On a failed save, the rider takes [roll]1d6[/roll] face plant damage.

Blazing Ride. Burn a second level spell slot. If another ride skill is casted, this skill’s duration is zero. The rider may travel on ampestri board at two times the ampestri board’s walk speed for 15 minutes. If the rider or ampestri board takes damage, the rider must make a DC 15 Athletics or Strength saving throw. On a failed save, the rider takes [roll]2d6[/roll] face plant damage. At the end of the skill’s duration, the ampestri takes 2 levels of exhaustion.

Frightful Ride. Cannot be used in areas with tight spaces and short spans such as small buildings and winding caverns. Burn a fourth level spell slot. If another ride skill is casted, this skill’s duration is zero. The rider may travel on ampestri board at four times the ampestri board’s walk speed for 7.5 minutes. If the rider or ampestri board takes damage, the rider must make a DC 20 Athletics or Strength saving throw. On a failed save, the rider takes [roll]4d6[/roll] face plant damage. At the end of the skill’s duration, the Ampestri takes 4 levels of exhaustion.

Soul Ripping Ride. Cannot be used in areas with tight spaces and short spans such as small buildings and winding caverns. Burn an eighth level spell slot. If another ride skill is casted, this skill’s duration is zero. The rider may travel on ampestri board at eight times the ampestri board’s walk speed for 3.75 minutes. If the rider or ampestri board takes damage, the rider must make a DC 25 Athletics or Strength saving throw. On a failed save, the rider takes [roll]8d6[/roll] face plant damage. At the end of the skill’s duration, the Ampestri’s health drops down to zero and begins rolling death saving throws. On success, the Ampestri takes 5 levels of exhaustion.

Take Off. Burn a second level spell slot. For one turn, the ampestri board gains an additional 10 ft of movement.

NOTE: Switching to a different ride skill does not deactivate ending effects of the rides.

NOTE: The ride multiplier is intended to be applied last. If the ampestri gets buffs for an additional 5 ft, blazing ride will double the sum = 2 X (30 + 5 + …).
