In the wake of producing OSR conversion booklets for Calidar's new Series 3 collection, it occurred to me that the mechanics to calculate monsters’ experience points are unnecessarily fiddly and not always clear. I took a closer look at the system presented in the Rules Cyclopedia, pages 127-128. The standard process involves two sets of numbers that should be added up. One is the basic XP based on HD, and the other a bonus that is multiplied by the number of the monster’s special abilities. To make matters worse, the chart ends at 20 HD. After tallying scores of those XPs ad nauseam I thought of an alternate and simpler approach. I also questioned the extremely low value assigned to special abilities of monsters with few or less than 1 HD.
With this in mind, I came up with the idea of having just one set of values that could be multiplied directly by the number special abilities, plus one. So for example a HD ½*** creature would be worth 5 x 4 = 20 XP instead of the Rules Cyclopedia's mechanics calling for 5 + (1 x 3) = 8 XP. There’s a big difference but I don’t see this as a critical issue because, if anything, it enables low-level PCs to rise faster through the initial levels of play. Giving a 15 XP bonus for some tiny critter with, say, abilities like charm, poison, and some limited spellcasting, is somewhat better than just a lousy 3 XP bonus. Fortunately, this discrepancy gradually decreases to almost match standard XPs for 36 HD monsters.
Here’s the standard XP table, expanded to 36 HD.

You’ll notice the separate XP rows for “plusses” at levels 1-9 are now gone, again for simplicity. The extra XPs for special attacks more than make up for the deletion, at least in the long run.
Asterisks and Special Abilities
What constitutes a Special Attack isn’t entirely well defined. Here’s what I’m thinking:
- All special attacks listed on page 154, including Acid, Blindness, Charge, Charm, Continuous Damage, Disease, Energy Drain, Paralysis, Petrification, Poison, Spellcasting, Swallow, Swoop, and Trample.
- Special defenses, such as: immunity to normal weapons, spell immunity, and other types of immunities likely to affect combat.
- Magic items affecting combat, such as armor, weapons, and items with spell-like powers (one asterisk per power).
- Natural abilities affecting combat, such as breath weapons and other magical attacks, as well as others that aren’t magical, such as for example a thief’s backstab or a fighter’s weapon mastery (one asterisk per skill level).
Don’t forget that spellcasting awards one asterisk for each 2 spell levels that can be memorized. So a 3rd level spellcaster should get 2 asterisks. Use your discretion to add or remove asterisks based on relevance.
Optional Rewards
Clearly, experience is earned when heroes circumvent or otherwise deal with a monster in ways other than combat. I've been toying with a system that helps estimate experience rewards for accomplishing other goals. I've implemented this in the latest Calidar adventure module (and I'm hoping for some feedback on this). Here's the material from Adventures in Alfdain, a collection of short adventures easily portable to D&D BECMI:
Heroes earn achievement bonuses in addition to normal
gains from combat and treasure. Awards are suggested at the end of each
adventure. A Basic Reward amounts to
10% of the experience between a hero’s previous and upcoming experience
thresholds.
For example: A novice fighter’s base experience starts presumably at “0” in the chosen RPG. The next career threshold may require an experience of 2,000. An entry-level adventure’s Basic Reward, therefore, amounts to no less than a +200 experience bonus until the next career threshold has been reached. Basic Rewards, therefore, become increasingly greater as the heroes’ careers progress.
Multiple Basic Rewards are often allocated to important adventuring goals, while minor ones may only yield fractions thereof. Use common sense and fairness when awarding these experience bonuses. Basic Rewards are allocated to each hero individually; they aren’t collective bonuses to be divided among survivors. Notoriety Points (NP) are also awarded in some of the adventures (see CAL1 pp. 86).
