Infinity RPG
Posted: October 11th, 2014, 11:16 pmFeedback and constructive criticism welcome...
Introduction:
This is still just a rough skeleton, and there are still gaps big enough to run a TAG through.
The intent of this system is to keep as close to that of the miniatures game as possible while adding enough detail to create a fun, action-oriented roleplaying game. Ownership of the Infinity book is required, as the background and many lists, such as weapons, are not duplicated here. Of course, having all the Infinity books gives you access to that much more fun.
During this "development phase," default back to the Infinity rulebook for anything that seems ambiguous.
Core System:
The core system of the Infinity RPG is almost exactly the same as the miniatures game, and adds more detail about the magnitude of a success or failure.
Normal Rolls:
Roll a d20 against a target number - any result equal to or less than the target is a success.
The target number will typically be an Attribute + Skill, modified by the situation as necessary.
A success has a Level of Effect equal to the die roll divided by three, rounding down.
A failure has a Level of Failure equal to the target number minus the die roll, divided by three, rounding down.
Face to Face Rolls:
Both sides roll d20s against their target numbers - the highest roll equal to or less than its target is a success.
A success has a Level of Effect equal to the successful die roll divided by three, rounding down, minus the highest unsuccessful die roll, also divided by three, rounding down.
RPG Attributes:
The Infinity RPG uses only two primary attributes to represent your character. These are exactly the same as the tabletop game:
Physical Capability (PH) includes strength, agility, and physical resilience.
Mental Capability (WIP) includes intelligence, will power, wisdom, and mental fortitude.
It uses two secondary attributes, both familiar from the miniatures game. Movement translates directly, and Wounds have been given a larger range, allowing for less granularity than OK - Unconscious - Dead.
Movement defines how far you can move in a period of time, and can be modified by equipment, encumbrance, and /or training.
Wounds represent how much damage you can take before being affected or overcome by your injuries.
There are eight skills in the Infinity RPG. Any untrained skill starts with a value of - 3 and can be trained up to 6.
Masteries allow Skills to be used in unique or specific ways.
Attributes - PH and WIP both start at 6 and you have 10 points to distribute between the two. MOV starts at 4-4 for humans. W starts equal to your PH attribute. Both MOV and W can be increased by Masteries (see below).
Skills - pick 4 Skills to start at 0; all others start at -3. You have 12 points to distribute amongst all your Skills, and any Skill improvement beyond +3 costs 2 points instead of 1. Example: You decide that Dodge is one of the skills you'd like to start at 0, and want to buy it up to 4. You spend 3 of your points to get to 3 and then 2 more, for a total cost of 5 points, to get to Dodge 4.
Masteries - pick 4 Masteries. You may choose the same Mastery more than once of it has multiple levels or multiple types.
Equipment - you have ?? to spend on starting equipment.
Conflict (Turns):
When it comes time to resolve a conflict, either combat or otherwise, follow this sequence.
Roll Initiative - every character rolls a d20 against their WIP, just like the miniatures game, and the highest roll for each side is their Initiative.
The side with the highest Initiative acts first, with a number of Actions equal to the number of characters or NPCs on that side. These Actions forum your Action Pool.
Actions can be used by any character or NPC.
A single character or NPC can use multiple actions, but suffers a modifier of -3 to rolls on the second action, -6 to the third, and so on.
Any Action taken in an opponent's Line of Fire or Zone of Control allows the opportunity for a Reaction.
The side with the next highest Initiative acts second, with their Actions, and so on till all sides have acted.
Actions & Reactions:
An Action or Reaction consists of using one or more skills.
An Action may consist of one or two Short Skills (including Movement Short Skills), or one Long Skill. Taking an Action reduces your side's Action Pool by one.
The same Short Skill may not be used twice in the same Action, excluding Movement Short Skills, exactly as the Infinity rules.
A Reaction consists of one Short Skill. A Reaction does not reduce your side's Action Pool.
Your first Action or Reaction is made with no modifier to the roll. Your second Action or Reaction has a -3 modifier to the roll. Your third, -6, and so on.
When acting, you may reserve one of your Actions for future use during the Turn as a Reaction. If not taken before the end of the Turn, the opportunity is lost.
Example: Knowing that he has tripped an alarm and security could enter the room at any moment, Carlos reserves his unmodified roll for use as a Reaction, and takes a -3 modifier to his Action of Hacking a corporate terminal, as if it were his second Action.
Combat Rolls:
Combat uses the basic core mechanic to determine success and Level of Effect.
Example: Carlos and a security guard are shooting at each other, both with a target of 13. On the Face to face Roll, Carlos rolls a 9 and the guard rolls an 18. Carlos has hit with a Level of Effect of 3.
When hit, you roll a d20 and add your ARM value against a target number of the weapon's damage value plus the Level of Effect for the strike.
If the modified roll is over the target, the armor absorbs the damage. Otherwise, subtract the modified roll from the target and divide by three, rounding up. This is the damage taken.
Example (continued): Carlos adds 3 to his weapon's DAM value of 13, making a target of 16 for the guard. The guard rolls a 9 and adds his ARM of 3, for a total of 12. The difference between target and roll is 4, resulting in 2 Wounds.
