An arbitrary idea sparked in me today, giving birth to the Hogwarts Water Polo Tournament. I came up with the mechanics literally today, so please don't expect everything go to 100% smoothly. That being said though, I do still welcome your participation and hope we can all at least have a lovely time! While this is still a work in progress, I have decided to post it now to gauge some interest, and will hopefully be edited to the finished product by the time we have a full house of players.

STATS

STRUCTURE

There are 12 rounds in each match. Each match is split up into quarters, with each quarter containing three rounds. Each round follows the structure below:

ACTIONS

Each player (except for the goalie, who only has one action per round unless they exit the goal, in which case they can have three as well) three actions per round, one from the three sections below. Conditional actions are allowed (ie. if A successfully passes ball to B with overhand pass, B shoots overhand shot). All rolls include a d20, if not marked otherwise.

1. Movement and Positioning

Reducio

Tread Water: Mandatory for every round, does not count as an action. Starting from the lowest stamina + 5 in the first round and increasing by one unit per round, if this check is not passed, the player will be unable to shoot this round. There is a -5 to both accuracy and evasion. If this happens to the goalie, they will struggle to stay high and cannot block against non-basic shoots.
Tread Hold: Holding the ball while treading, no movement and no rolls.
Swim Sprint: Swimming with the ball, one of the following styles must be declared.
1. Head up Dribble [standard carry]: Normal movement, no buffs or debuffs
2. Head down Dribble: No accuracy or evasion against defenders if they catch up, speed check rolled on an advantage for the dribbler.
3. Side Dribble: Dribble by holding with one hand, better protection and versatility to switch sides against opponents. Evasion is rolled on the advantage for the dribbler.
4. Shielded Dribble: Can only be used with defender present, body is positioned between defender and ball, arm extended to protect the ball. Opponents suffer a disadvantage of -5 to steal.
5. Push ahead Carry: The ball is pushed ahead while the dribbler swims behind. Lowered control over the ball but faster speed
NOTE: one speed check (stamina + accuracy) is rolled for every carry style to see if the defender catches up. Upon critical success, there is a +5 advantage for shooting if the dribbler intends to shoot, with the advantage decreasing by 1 each time the ball is passed onto someone else.
NOTE: at the beginning, there will be a sprint to see who gets the ball. If a crit success is rolled on this, the player gains +5 advantage if they choose to immediately shoot.
Drive/Cut: A short, sudden burst of movement without the ball to get free from a defender. This can often be done before receiving a pass, taking a quick shot, or forcing a defender to fowl. By succeeding, the player gets into open water and can swim sprint the next round. This will be an evasion + strength vs. accuracy + strength roll to see if they can be shaken off. If the defender is not currently tagging, there is a disadvantage of -5 for the defender's accuracy if they do tag on the next round.
Change Direction: A rapid pivot while swimming to shake a defender or adjust position. If there is a defender tagging, this will be an evasion + strength vs. accuracy + strength roll to see if they can be shaken off. If a defender is trying to tag, this will be an advantageous +5 evasion for the player changing direction.
Swim Back on Defence/Offence: This happens when the game changes and the ball lands on the other side of the court, requiring players to go to the other side. This action does not require rolls.
Enter/Exit the Goal: the goalie can exit the goal and participate in the game, leaving it undefended. This action does not require rolls.

2. Physical/Ball Contact

Reducio

Steal Ball: An attempt to take the ball from an opponent. Roll is defender accuracy + strength vs. attacker evasion + strength.
Intercept Ball: to cut off a pass mid-flight. Accuracy contest between defender and attacker. If both are the same, ball becomes lose and ball grab starts again.
Ball Grab: the initial scramble when ball is free. This is a contested Accuracy roll between every player that attempts to grab the ball.
Ball Recovery: recover loose ball after block, miss, or deflection. This requires no roll.
Protect Ball: passive defence of the ball. +5 advantage in steal attempts.
Jostle for Position: physical battle without the ball. Roll is attacker strength + evasion vs. defender strength + accuracy. The winner gains inside water position and has +5 accuracy shooting advantage next receive. If the attacker is pushed out, they -5 accuracy shooting disadvantage next receive.
Body Block: to prevent movement or block the pass lane. Roll is defender strength + wisdom vs attacker evasionx2. If successful, target cannot drive/cut or swim sprint next round. All passes to them suffer -3 accuracy.
Disrupt Shot: defender interrupts the shot during shot motion. Roll is defender accuracy + evasion vs shooter accuracyx2. If success, attacker -5 accuracy. If critical success, -5 accuracy and transforms in body block.
Press: to commit tightly to one opponent. for each round of pressing on one opponent, an accuracy contest is rolled to determine if the ball would be automatically intercepted. A strength contest is rolled to determine if the target would be unable to make other moves. The target also suffers -3 evasion.
Double Team: two defenders press onto one opponent. roll is, with d20, defenders' strength+accuracy vs. attacker's strength + accuracy. If one defender rolls higher than the attacker, this results in a steal, if both players' combined efforts are required, this results in a random pass to a teammate, with chances of the ball being intercepted.
Force Bad Angle: forcing the attacker into a bad position to reduce shot quality. Roll is defender d20 + wisdom + accuracy vs. attacker d20 + wisdom + evasion. If success, -5 accuracy in shot.

Draw Foul: force illegal contact by bouncing the ball in the water when any physical contact is initiated by defender. roll is d20 + 5 + drawer's wisdom vs. d20 + opponent's wisdom. If succeeded, the drawer automatically gets the ball.
Commit Foul: The foul DC is average opponent players' wisdom + 15.
Exclusion foul: player is excluded for one round. Holding or sinking an opponent that doesn't have the ball. If successful, all evasion and accuracy are removed and -100 hp.
Penalty foul: when a defender takes away a probable goal from the 5m area. If successful, the goal is blocked. this results in an automatic penalty shot if discovered.

3. Shots & Passes
Critical Hit: the ball depletes the goalie's hp by 50 if it is blocked, +5 advantage if not
Critical Miss: the ball falls out of the player's hand, ball grabs begin again
All passes to teammates must be within a 7 number range.

Reducio

Overhand Shot / Pass [baseline] [basic shot] : A reliable, balanced shot for all situations with no buffs or debuffs. This shot can be used by anyone. Shooter accuracy + strength vs. goalie accuracy + wisdom.
Quick Shot [basic shot]: Immediate release after catching the ball, must have someone throw the ball to you in the same round. This shot can be used by anyone. Goalie rolls as a -5, penalised for reaction time.
Outside Shot / Pass [basic shot]: Outside shots are usually shot from longer distances. They can also be used for points to pass to wings or the centre forward. The goalie can also use this pass. The target of this shot must have at least one person in the middle between them and the shooter (eg. point -> wing / point -> goalie). A strength and accuracy check of lowest strength/accuracy average + 1o must be checked. Due to high momentum, if the goalie blocks this hit, there is a 50% base chance of losing 50 hp, added by ten in every five in strength of attacker. This will not happen to the person receiving the ball if it is a pass.
Lob Shot / Pass [basic shot]: A shot over the heads of other players. This type of shot or pass completely ignores all defenders. To shoot this type of shot the shooter must pass two checks. First, there is a 25% chance they do not get high enough for a lob shot/pass. Then, a strength check of the lowest strength + 10.
Corner Shot: A shot aimed at the corner of the goal. To shoot this type of shot the shooter must pass a accuracy check of the lowest accuracy + 10.
Skip Shot: Ball bounces off the water mid-distance before hitting the goal. There is a base 50% chance of skip failure, reduced by ten in every five in wisdom. If the skip succeeded, goalie rolls as a -7.
Push Shot: Controlled shot using hand/wrist with minimal arm swing. For close up scoring and can only be used by centre forwards. For every two in strength the goalie suffers one disadvantage. This shot can only be used if you also swim up to the goal in the same round.
Feint Shot: A real shot followed by one or more that are fake, this is risky if there are nearby defenders but has high payoffs. Shooter accuracy + wisdom x (times of feint + 1) vs. goalie accuracy + wisdom. With each time of feint, risk of ball being stolen grows, see below in physical contact.
Backhand Shot: Reverse shot going in blind that can only be done by the centre forward. There is a 50% chance of failure on luck and an accuracy check of the lowest accuracy + 15. There is only a 10% chance of this shot being blocked.
Turn Shot: Spin move to rotate and shoot. Shooter strength + evasion vs. goalie accuracy + wisdom. If being defended strength contest conducted gives +5 advantage to defender.
Wing Angle Shot: Can only be done by wings, high in accuracy. Can only be done if there is a pass or drive in the same round. Shooter accuracy + wisdom vs. goalie accuracy + wisdom - 5.
Power Shot: A full-force long throw with raw force and little accuracy. Player only has one action next round after this shot. Shooter accuracy + strengthx2 vs. goalie accuracyx2 + wisdom. If the goalie blocks this hit, there is a 50% base chance of losing 100 hp, added by ten in every five in strength of the attacker.
Penalty Shot: This is not an action to choose but one that happens automatically after a foul. This is an accuracy vs. accuracy roll for the shooter against the goalie.
NOTE: receiving a pass does not count as an action. Players may have an action that is its direct result instead (shooting).

POSITIONS

Goalkeeper: high wisdom (ball prediction) and accuracy (ball blocking)
Wing: high accuracy (tight angle finishing) and evasion (catching under pressure)
Centre Forward: high strength (holding position/push shots) and accuracy (backhands, etc)
Flat: high accuracy (mid range shots) and evasion (drives/cuts)
Point: high accuracy (passing) and strength (long shots)

POSITION ROTATION: the position you have signed up for is only your starting positions. All positions (other than goal keeper) can rotate. The only time when they can rotate is when players are swimming back for defence/offence. {WIP}
