To create an Opponent for your game, follow these steps

1. Choose an appropriate Monster Role
2. Choose or Create a Background
3. Determine Challenge Rating
4. Adjust feats accordingly

Monster Roles

The monster roles developed by ValhallaGH, and made into google Docs by Tezrak, have been slightly modified by myself to comply with my rules.

Artillery

A skilled combatant that relies on ranged attacks to cause damage. This can be used to represent Master Archers, or a dread warlock.

Brute

A melee combatant that relies on strength and toughness to out fight it's combatants. A hulking behemoth, a vicious beast, or even an armored juggernaut are all good fits.

Lurker

A master of stealth, that attacks from hiding. Ninjas or cave dwelling threats are good fits.

Priest

A mystic warrior who uses both his faith and martial prowess to fight. This role is also a good fit for enemies that have amix of supernatural and martial prowess, like some devils or demons.

Sorceror

An Arcane power user, fragile and unflexible, but with much power. Use the Artillery role for evokers, and this role for sorcerors with a different flavor.

Skirmisher

A skilled combatant that relies on movement to increase it's potential in combat. Martial artists, dashing swordsmen or lithe and agile predators make good fits.

Wizard

An Arcane power user, fragile and flexible in his range of powers. As the sorceror, use the Artillery role for evokers

These Roles can be used to create animals, aberrations, undead, monstruos humanoids and more, as well as quickly statted up enemies.

Background

When creating a monster, list the feats, traits and abilties that distinguish it, creating a background. This Background will have a Level Lag. The Level Lag of a monster is a function of it's Background, as well as any applied templates. The rules for generating background and templates can be found Here.

Challenge Rating

To create a suitable Monster as a challenge for a group of players, determine first it's Challenge Rating. This determines the power of the cerature. A creature's Challenge Rating is equal to:

CR= Level Lag + Monster Role Level

CR is a convenient number used to indicate the relative danger presented by a monster, trap, hazard, or other encounter—the higher the CR, the more dangerous the encounter. APL stands for average party Level and is equal to the average level of the members of the party. If the party consists of more than 4 players, increase the APL by 1. If the party consists of less than 4, decrease the APL by 1.

Adjustments

Some of the feats from the monster roles do not really fit, or maybe some are more appropriate. Sometimes some skills are more appropriate than the default array. The Narrator is free to adjust these as necessary, trying to keep balance in mind.
