A Certain Role-playing Game

Started out as just an idea, then /tg/ picked it up. Basically, it's a game set in the To Aru universe complete with psychic powers and magic. (the word complete is used very loosely) It's not a dice-pool system, it's a d10 roll-under system.

Base Stats

There are four base stats:

Physical - Covers everything physical strength and constitution.

Mental - Not only sheer intelligence, it's also the speed of thought and everything that's based in your head.

Social - How much of a people person you are.

Coordination - Agility, speed, and dexterity.

Generate stats by rolling 5 sets of 2d10 and assigning the best four to one stat each.

The player is then given 30 points to allocate to Level and skills.

One ESPer level costs 5 points

A skill costs as many points as it's bonus. (Running 4 costs 4 points)(There's no skill list, skills are completely freeform)

OR you can roll on the Level table, coming up!

HP: Number of hit points is your Physical stat multiplied by 5. At 0 hit points or below, roll against your physical each turn. On a failure you collapse and are unconscious. At -100% of your maximum hit points, make the same check but a failure means death.

Base Mechanic

Skill Rolls: A skill gives a bonus to your base stat (Running 4 gives a +4 bonus to Physical, Knowledge (Trees) 8 gives +8 to Mental if Trees come into play on a theoretical level.), which you then roll 2d10 and try to roll under the resulting number. 19 and 20 are critical failures, 2 and 3 are Spectacular Successes.

Powers: Powers are determined by rolling on the tables found below. Every combat round, an ESPer rolls a number of dice equal to their level to determine the amount of power points they can spend that turn. Power points are pretty abstract, but the more the more powerful the effect is. The ESPer can also choose to save half of those power points for the next round, thus "charging" their power.

Powers in Combat: (tentative idea) Each turn in combat, an esper can choose to spend the points they rolled for the turn or save up to half of the unused points. If an esper is ever holding more than the maximum number of points they could roll in a single turn (so 10 for level 1s, 20 for level 2s, 30 for level 3s, etc), then they lose all points over the maximum and take that much damage. The number of points you have is the base damage you can do with an attack. This assumes a short range attack against one target. These points of damage can either be used for the attack or be spent to modify the attack to have a longer range, to cover a larger area of effect or to buy additional effects on the attack such as an electrical attack that stuns foes.

Attack Effects: Rather than have a list of power effects, there will be guidelines for how much effects cost. GMs have the last word on how much a particular effect will cost. Small effects will cost 1 point. Medium effects will cost 3. Large effects cost 5. Each effect beyond the first costs an additional point. (ex: 3 small effects will cost 1+2+2 points = 5 points. 2 large effects would cost 5+6=11 points)

There are two cases for when effects need to be applied to attacks. The first is when the attack gives a mechanical benefit beyond simply doing damage.

Examples: Small: plants coming up from the ground and making grabs at your feet to try to trip you

Medium: A stunning effect to a shock, temporarily dropping you

Large: Plants wrap around someone and squeeze tightly, immobilizing them

The second is when the attack does something that deviates from what the power originally does. Small effects push the original power a little. Medium would be effects and addendums of the first power. Large would be huge changes and weird stuff.

Examples: Small: manipulating gravity to directly hit someone with force

Medium: Using electromagnetism to create a blade out of iron particles from the ground

Large: Using gravity to bend light

Obviously, powers like teleportation that don't have direct combat application wouldn't be able to do damage in these steps without use of added effects. They might also need different distance/range charts for balance.

Preliminary Range/AOE info: Each point of damage that is instead put into AOE or range increases the effect of the attack by 10 square yards of area or 10 yards of distance, with a maximum of 100 yards (10 points) for range and no maximum limit for area of effect of the attack.

Accuracy and Dodging: Upon declaring an attack using esper powers, the attacker makes an accuracy roll. For attacks doing physical damage, roll d10 against your coordination For this roll, add your ESPer level and the number of points spent on increasing the AOE of the attack to your coordination. Subtract 1 from your coordination for each point above 3 spent on increasing the range of the attack. The defender rolls coordination. Whoever succeeds with a higher margin of success wins (hits with or dodges the attack). For mental attacks, use the mental stat in place of coordination for both attacker and defender.

Defensive Abilities: If you have stored up esper powers when someone successfully attacks you, you can spend those points to negate some of the damage at the rate of 4 stored points per 1 point of damage negated. Describe how you do this with your power. Ex: bringing up a sheet of ice to block a launched rock, cutting through some of the vines of an attacking plant using a blade of vibrating iron particles, etc.

Critical Failures: When rolling dice each turn to determine power points, an esper can lose control of their power and suffer backlash from it. A level one cannot have a critical failure. A level 2 that rolls 2 or lower on both dice has a critical failure. A level 3 that rolls 2 or lower on 2 of their 3 dice has a critical failure. A level 4 that rolls 3 or lower on 3 of their 4 dice has a critical failure. A level 5 that rolls 3 or lower on 3 of their 5 dice has a critical failure. On a critical failure, the esper gains no points this round and instead loses all stored points and takes damage equal to the points they would have gained plus the stored points they lost.
