Experience (X.P.).jpg

A measure of the character’s ability in his or her chosen profession, the character’s class. Upon achieving 1st level, the character’s experience points are set to zero. Thereafter, to accumulate experience, the character must participate in combat and survive, thereafter gaining additional experience through treasure. When a sufficient number of experience points have been gained, the character will gain experience levels. Experience levels are detailed upon pages relating to the assassin, bard, cleric, druid, fighter, illusionist, mage, monk, paladin, ranger and thief.

Rewarding X.P.

Experience points (x.p.) are assigned by how much weapon damage the character takes and causes. The system promotes risk-taking. Taking damage is considered more enlightening than causing damage, and so the total ratio of experience rewarded is 4:1 in favour of taking damage rather than causing it. Part of this is a substantial reward for observers who see the damage taken — so that persons who "take part" in a combat, even if they take or cause no damage, are still able gain a small share of the overall experience rewarded. The system makes an effort to reward those who act in concert and are ready to take hits for one another. See below for a definition of taking part.

20 x.p. is awarded for each hit point (h.p.) that the combatant takes.
10 x.p. is awarded for each h.p. that the combatant causes.
20 additional x.p. is awarded for the total damage that the friendly side takes in damage. This "bonus" damage is shared among all the combatants who have taken part, with henchmen, followers, retainers and hirelings receiving a lesser share than levelled persons, depending upon their status (see below).


Reciving experience does not depend on actually killing an enemy. So long as damage is either taken or caused, experience is rewarded, regardless of the outcome of the combat.

For example, Hector, Iolanthe and Jules take part in a combat. Hector causes 7 h.p. of damage and suffers 2. Meanwhile, Iolanthe causes 2 h.p. and takes 7. Finally, Jules causes no damage and takes no damage. Altogether, the party takes 9 h.p. of damage.

Hector receives 70 x.p. (10x7) for the damage he causes and 40 x.p. (20x2) for the damage he takes. Iolanthe receives 20 x.p. (20*2) for the damage she causes, and 140 x.p. (20x7) for the damage she takes. Jules receives nothing from causing or taking damage. However, the party as a whole receives an additional bonus 180 x.p. (20x9) from the total damage taken. This is divided evenly between the characters, so that each character receiving 60 additional experience. Hector’s total gain is 170 x.p.; Iolanthe gains 220 x.p.; and Jules gains 60 x.p.

This seems to punish Hector, as he did all the work fighting off the enemy. However, clearly Hector already knows how to fight, so doing what he knows isn’t really "gaining" experience. On the other hand, Iolanthe learns to be careful about getting in the way of the enemy’s weapons; her learning experience has been deeper. Jules was both lucky and unlucky, but at least he learned something by taking part.

Taking Part

To receive bonus experience for taking part, the combatant must either roll to hit, using missiles or hand-to-hand weapons, or casting a spell; or they must be attacked at some point, thereby risking life and limb. If either has occurred at least once in a combat, the combatant is considered to have taken part. Actually hitting or being hit is not necessary. Obvuiously, it is better to risk being hit, and to take damage, than it is to hang back safely in an attempt to do damage. The distribution therefore punishes cowards and spellcasters who refuse to engage when combat occurs.

If a combatant has no actual chance of hitting an enemy, due to the enemy's armour class or natural defenses (hit only by magic, for instance), combatants are not considered to have taken part unless they submit themselves to attack. This may seem pointless, but damage taken by a weaker opponent can be seen as a sacrifice, enabling a stronger ally to act more effectively for not having taken damage that round. This kind of sacrifice is awarded due experience for that reason.

Therefore, characters of low level in a mixed party can therefore participate meaningfully, taking hits (and experience) through bravery and sacrifice. Consider what this means to a 1st level fighter who joins a 6th level party; while the 1st level may be able to take only one hit, the experience gained would be a substantial amount to the 1st level, and the treasure received after the fact would likely boost the fighter to 2nd level. In this way a low-level player character can quickly jump levels towards becoming effective.

X.P. for Treasure

Experience is also gained through the acquisition of coins, gems, jewellery and other treasure, measured in gold pieces (g.p.). Treasure is defined as wealth gained through plunder, or for services rendered, when those services include risk to life and limb. Experience from treasure is awarded at a rate of 1 x.p. per 1 g.p.

Some suspension of belief is required, but in game terms the system allows the players to reward characters themselves for acting appropriately or with great courage. If some players consistently hang back and take few risks, the rest of the party can arbitrarily decide not to share out treasure and x.p. for that reason. This is an essential part of the game's payoff for risks taken. The game has no rules dictating how treasure is to be shared out, because it is expected the players will invent their own method.

Experience is also received for magic items that are found as treasure. Each item is assigned an experience bonus that the character receives. Magic items have no gold piece value.

X.P. from the Use of Magic

Magic spells that cause damage to single persons should grant an award of 10 x.p. per h.p. This includes spells such as cause light wounds, chromatic orb, dust devil, fire trap, heat metal, insect plague, magic missile, magic stone, Melf's arrow, phantasmal bow, spike stones and spiritual hammer, among like spells.

Granting this award to area effect spells, however, would provide too much experience for the casting of a single spell. Therefore, the rule is adjusted as follows. With spells such as burning hands or fireball, and some elements of chromatic orb, there is a set damage that is applied to all victims of the spell. This number is granted an award of 10 x.p. per point.

The DM should also calculate the total damage caused to all recipients of the spell, multiplying this total by 3 x.p. per point. If this number is higher than the 10 x.p. award for the set damage of the spell, then the greater award is given. For example, the mage Korin delivers a fireball that causes 21 damage to seven creatures. This gives a minimum award of 210 x.p., unless every one of the four makes saving throw, in which case it would be 100 x.p. However, if Korin’s spell causes a total of 75 damage to the seven targets, multiplied by 3 x.p. this would be a total of 225 x.p. This higher number would then be given.

Other area effect spells, such as meteor shower, which gives a different amount of damage to those affected, would always have the 3 x.p. award applied to all the damage that was caused.

If a spell causes death to a combatant, without the damage being specified, such as with the spells death, phantasmal killer, or power word: kill, then the spellcaster is awarded 10 x.p. per point of it points that the victim possessed.

If a spell increases the amount of damage caused by a friendly combatant, or creates friendly combatants, the spellcaster is entitled to 5 x.p. per additional point of damage that is caused. This includes spells such as call woodland beings, chant, enlarge, flame blade, monster summoning, prayer, strength, summon elemental and like spells. Bards would also receive this benefit from the use of martial music. No direct award is granted to the caster for the damage taken by created allies, but the damage a summoned creature takes is added to the total x.p. bonus that is divided among all the combatants when the fight is done.

Experience (X.P.) -2.jpg

Finally, there are spells that provide hit points that can be lost by the caster or another friendly combatant, such as armour and phantom armour. For experience purposes, these spells are treated exactly like damage taken by the beneficiary of the spell, awarding 20 x.p. per point of damage lost, as well as that damage being added to the total damage compiled for the bonus experience award.
