A simple RPG that uses a multiclass leveling system with a modular "superpower" system atop the basic classes.

Basis: d20 (for now)

Classes:

• Classes provide bonuses to attributes such as:
  • Core attributes: str dex con int wis cha
  • Adventuring skills: magic, fighting, defense, skill
  • Hit Points, Skill Points
• Each level, everyone gets two talents:
  • Talents can come from class or subclass lists:
    • Example: Fighters have many combat-related talents such as Power Attack and Cleave
    • Paladins, a subclass of Fighter, have more Paladin-specific talents such as Aura, Bless Weapon, and Lay on Hands
  • Spells are talents too. A wizard might take Burning Hands and Magic Missile at level 1. They might also take non-spell talents like Counterspell, Dispel Magic, and Empower Spell.
  • Some talents give powerful, passive bonuses, like Weapon Focus (grants +2 to hit with weapons) or Spell Precision (grants +1 to critical threat range with spells). This allows PCs to improve their character without necessarily accruing many dozens of options in combat, especially at higher level.

Skills:

• A relatively minor part of the system, but a basic skill system still exists.
• Classes grant a certain number of Skill Points, which allow you to improve your skills.
• Skills come in 5 ranks of proficiency:
  • Untrained: you can only attempt certain, basic uses, rolling 1d20 + ability score
  • Trained: you can attempt any use of the skill, rolling 1d20 + skill bonus + ability score
  • Expert: you may take 10 on skill checks
  • Master: you gain advantage to all checks with this skill
  • Legend: you may roll a single d20 for a check, but all rolls under 10 gain +10

Adventuring skills:

• Attack is a modifier to all attacks with physical weapons (or unarmed)
• Defense is a modifier to all defensive actions, such as Dodge and Parry, or such as Strength or Constitution saves.
• Magic is a modifier to all magical or super-powered attacks.
• When your attack/defense/magic reaches +5, it is considered "rank 2". +10 corresponds to "rank 3", +15 to "rank 4", and +20 to "rank 5".
• Weapon attacks gain a bonus damage die for each rank of Attack above 1. Thus, a longsword attack at rank 1 might inflict 1d8 + Str damage, but that same sword at rank 2 inflicts 2d8 + Str damage.
• The same is true of magical attacks using the Magic skill. A rank 3 fire spell might inflict 3d8 + Cha damage, vs only 2d8 + Cha at rank 2.
• Some talents, spells, etc have a minimum rank. If the minimum rank of a physical attack is higher than your Attack rank, or if the minimum rank of a spell is higher than your Magic rank, you cannot use it.
