D&D to AD&D Conversion by Ian R Malcomson ====================== This is a little off-beat, since I've always considered the two games to be separate (if related). However, what follows is my thoughts on how to convert a D&D adventure to AD&D, based somewhat on the notes provided in Appendix 2 (p291-294) of the D&D Rules Cyclopaedia, but much expanded from there. Characters ========== Clerics, Fighters, Thieves and Magic-Users should be considered Humans of their respective Classes in AD&D. Note that, in D&D, Paladins, Knights, Avengers and Druids are, in D&D, "name"-level options for various alignments of Fighters and Clerics. They can be considered full members of their AD&D Classes (if there is an equivalent - i.e., D&D Druids can be considered AD&D Druids), with this note: by doing this, you are precluding the existence of lower level members of these Classes. I therefore recommend that, depending on the situation, a Neutral D&D Cleric can be considered a Druid, and a Lawful Fighter can be considered a Paladin. This is not to say that *every* Lawful Fighter should be converted to an AD&D Paladin, for instance. Judgement is advised. Ability Scores -------------No change in actual value (other than rolling percentile strength for Fighter types with 18 Str), but AD&D mods (for To Hit, etc.) should be re-calculated using the PHB. I generally modify the listed D&D Ability Scores for demi-humans by their AD&D Racial Modifiers, since D&D doesn't have Racial Mods. This is not really necessary - just a matter of personal taste. Note that certain listed stats (THAC0, AC, hit points, etc.) may need to be re- calculated depending on new AD&D modifiers. Alignment

--------The simplest misconception regarding the D&D system is that *all* Chaotic beings are Evil, all Lawful beings are Good, etc. However, this is simply not true. Instead, the Law-Chaos Alignment should be kept, and a Good-Evil component added depending on the nature of the being. Level ----For Fighters, Thieves, Clerics and Magic-Users: D&D 1-12 13-15 16-18 19-21 22-24 25-27 28-30 31-33 34-36

For Demi-humans: Elves become Fighter/Magi Dwarves become Fighters Halflings become Fighters Use Levels as stated (i.e., a 4th level Elf becomes a F/Mg of 4/4 level), with higher levels dependant on Fighter Combat Options as per:

** May be higher if optional level limit rules used Hit Points ---------D&D Classes use different Hit Dice (eg, a Cleric uses a d6 instead of a d8). Thus, when converting to AD&D, use the following guideline (note the levels indicated here refer to the converted AD&D levels): Fighter (et al): +(1d3-1) hit points/level to 9th, +1 hit point/level from 10th Cleric (et al): +(1d3-1) hit points/level to 9th, +1 hit point/level from 10th Mage: As stated (no change) Thief: +(1d3-1) hit points/level to 10th Elf F/Mg: +1 hit point/level to 9th, +1 hp at 10th, +2 hp/lvl from 11th Dwarf F: +(1d3-1) hit points to 9th, +3 hp/lvl from 13th Halfling F: +(1d4-1) hit points to 8th, +1d8 hit points at 9th, +3 hp/lvl from 10th Thief Abilities --------------Either re-calculate using PHB methods, or use the following table (based on Average Thief Ability table, DMG) to provide modifiers to the listed Thief Abilities for a D&D Character: Level* 1 2 3 4 5 6 7

* D&D/re-calculated AD&D level ** Ignore separate "Find Traps" D&D ability *** D&D Thieves gain 80% RL at 4th level - ignore this and use the above instead Backstabbing: re-calculate using new AD&D level Thief Ability Mods: Remember to add in Race and Dex mods to the resultant Thief Ability scores gained Note: In spite of the above guidelines, remember that no Thief Ability may be raised above 95, inclusive of Dex and Race mods. Yes, I know the Average Thief Table doesn't exactly follow this rule, but it does provide a quicker alternative to re- calculating using PHB rules. Armour Class -----------Take the basic Armour Type in D&D, and re-calculate using the following equivalencies: No Armour - same (except this is AC9 in D&D, and AC10 in AD&D) Leather - figure as either Leather, Studded or Ring Scale - Scale, or, optionally, Scale or Brigandine Chain - Chain, or, optionally, Chain, Banded or Splint Plate - Plate or Field Plate Suit - Full Plate Note that D&D allows for ACs from 19 to -20. In the (rare) instances where such extreme ACs appear, either re-calculate to use the (official) AC range of 10 to -10, or (optionally) divide the "excess" D&D AC (from 11 to 19, or from -11 to -20) by 2 (eg, AC 15 becomes AC10 + (5/2), or AC 13; AC -17 becomes AC -14). Saving Throws, THAC0, etc.

* Includes Dwarves, Elves and Halflings on the AD&D column; these D&D Classes use the D&D progression as listed for the other non-Fighter Classes Basically, a 36th level D&D Fighter who can wield 15 weapons will lose the ability to use 5 of them effectively (i.e., will be non-proficient) when translated into the AD&D game. This is simplistic. If you add in Weapon Mastery and Specialisation, things get a little bit more complicated to calculate. (NB: D&D Mastery Slots: 1 BS, 2 SK, 3 EX, 4 MS, 5 GM; AD&D Specialisation Slots: 1 Prof, 2 Melee/Thrown Spec., 3 Bow Spec.) Specialisation vs. Weapon Mastery --------------------------------If using standard (PHB) AD&D rules, assume that "Expert" Weapon Mastery level indicates Specialisation. If using the S&P Specialisation rules, figure Weapon Mastery thus: D&D Weapon Mastery Basic Skilled Expert Master Grand Master
AD&D S&P Specialisation Proficient Expertise Specialised* Mastery* High Mastery (C&T)**
* Assume "Expertise" and "Weapon of Choice" for non-Warrior Characters ** Or, alternatively, Grand Mastery if the PC in question is higher (in AD&D terms) than 14th level. Note the general warnings with respect to Grand Mastery described in the C&T book. Mystics ------Mystics are difficult, since the Monk is no longer part of the core AD&D rules. They can be converted to either Monks, as listed in the PHB1 or OA, or use the S&M Monk Class, or use the PHBR3 Warrior Monk Kit. The Mystic level should remain the same in the AD&D game. Spells ====== Spells per Level --------------Additional spells should be selected as memorised according to the following table (notation is 1st/2nd/3rd/etc.). Note that Wisdom spell bonus should also be taken into account. Negative "additions" indicate a drop in a spell of the specified level.

Persuasion: Drop, or use PHBR2 Singing: Singing (General) Storytelling: Subset of Singing (General) Monsters ======== These guidelines are from the Rules Cyclopaedia. Note that where an equivalent monster exists in the AD&D game, it is better to use the stats for the AD&D version than to convert the D&D version. All stats remain unchanged, except.... Save As: use standard AD&D rules (save as F of HD, unless specific monster type is closer to another Class) Morale: 2=2 or 3; 3=4 or 5; 4=6 or 7; 5=8; 6=9 or 10; 7=11 or 12; 8=13 or 14; 9=15; 10=16 or 17; 11=18 or 19; 12=20 Alignment: Add Good-Evil axis depending on description XP: Re-calculate using DMG rules Frequency: Common = Common, Rare = Uncommon, Very Rare = Rare or Very Rare Note regarding D&D Monsters: Most of the monsters from the D&D game have equivalents in the AD&D Monstrous Manual. Those that don't are highly likely to be in the Mystara Monstrous Compendium (which is OOP, unfortunately). Dragons --Why do Dragons cause a problem when converting between any version of D&D or AD&D? Oh, well.... The easiest assumption to make is this: Small Dragon - equivalent to Hatchling or Very Young Large Dragon - equivalent to Juvenile or Young Adult Huge Dragon - equivalent to Mature Adult or Old Note that, depending on PC level, and the situation, discretion can be used with these rough equivalencies (eg, a Huge Dragon may represent a Great Wyrm in a high- level adventure). Treasure ======== Treasure Types -------------The following can be used to determine rough equivalencies of type codes. Since the amount of coinage varies widely, I've based my assumptions on magical item content of lair first. D&D

Magical Items ============= Another one of those horrible equivalency lists coming up...... Note: most of the rules that govern the use of specific items in the D&D game are compatible with the AD&D game, so the D&D description for an item that doesn't appear in the AD&D game is just as good (if not better) than taking an AD&D equivalent. Only items that do not appear, or have different names to, those listed in the DMG are presented here. Some of my suggestions are based on personal choice (which means they might not make sense to you), so take them for what they are.... Potions ------Agility - Speed Antidote - treat as an antivenene Blending - Rainbow Hues Bug Repellent - Animal Control (insect type) Defence - Oil of Slipperiness Dreamspeech - ESP Elasticity - Oil of Slipperiness Elemental Form - Oil of Elemental Invulnerability Ethereality - Oil of Etherealness Fortitude - Vitality or Elixir of Health Freedom - Oil of Slipperiness (again) Luck - Philtre of Glibness Merging - Polymorph Self Sight - Oil of Disenchantment Speech - ESP Strength - Giant Strength Super-Healing - Extra-Healing Swimming - Water Breathing Scrolls ------Communication - replace with Crystal Ball with Clairvoyance Creation - replace with Nolzur's Marvellous Pigments Delay - replace with spell scroll Equipment - replace with Robe of Useful Items Illumination - replace with Wand of Illumination Mages - replace with spell scroll containing Identify

Survival - Sustenance Truthfulness - cursed Ring of Truth: wearer cannot lie Miscellaneous ------------Amulet of Protection from Crystal Balls & ESP - Amulet of Proof against Detection & Location Boat, Undersea - Apparatus of Kwalish Boots of Travelling & Leaping - Boots of Striding & Springing Chime of Time - glorified water clock (well, it's getting late...) Displacer Cloak - Cloak of Displacement Egg of Wonder - Bag of Tricks Helm of Alignment Changing - Helm of Opposite Alignment Helm of Reading - Helm of Comprehending Languages & Reading Magic Lamp, Hurricane - as Lamp of Long Burning, except hurricane blast plus stormy rain come hacking out when the shutter is raised first time in a day Lamp of Long Burning - burns until doused Muzzle of Training - Iron Bands of Bilarro (well, close enough....) Nail, Finger - Amulet of Inescapable Location Nail of Pointing - Wand of Enemy Detection Ointment - Keoghtom's Ointment Pouch of Security - Bucknard's Everfull Purse Quill of Copying - Quaal's Feather Token Slate of Identification - Lens of Detection Wheel of Floating - Wings of Flying Wheel of Fortune - Deck of Many Things Wheel, Square - Horseshoes of a Zephyr or Horseshoes of Speed Weapons & Armour ---------------Most of these are pretty straightforward. There are a few weird ones in D&D, but nothing that can't be translated from it's name into a useable item in AD&D. Conclusion ========== Despite appearances, the D&D game is not a "baby version" of AD&D - it is a different game, that has, over a longer period of time than AD&D, developed down it's own path with it's own set of devotees. The above attempt at producing a fairly comprehensive conversion guide shows this. When converting a D&D module for use with AD&D, you have to remember that the module was originally written for a different, albeit similar, game, with different balances in place. D&D Characters, for example, are generally weaker than AD&D Characters at low levels, but eventually overtake them as the levels progress. A 20th level Magic-User, for instance, is actually more powerful than a 20th level Wizard, and not just through spells. However, D&D Characters, regardless of level, do tend to have less hit points, lower Ability Scores, and less choice of spells and special abilities than their AD&D cousins.
