Blue Book D&D, my name for a fusion of Holmes Basic D&D with Cook/Marsh Expert. But lately it's been on my mind, and I've thought more about cleaning it up and solidifying it for my own future games.
Specifically I've been thinking a lot lately about tweaks to ability scores. Holmes is minimal with bonuses, copying OD&D's Dexterity and Constitution bonuses, but increasing the Constitution bonuses to hit points at 17 and 18. Moldvay, meanwhile, sets out with the standardized thresholds: 13-15 for +1, 16-17 for +2, and 18 for +3, with corresponding penalties on the low side.
But Moldvay's attribute curve is misleading. One +1 is not the same as another, if the first bonus is on 1d6 and the second bonus is on 1d20. +1 to 1d6 is 16.67%, while +1 to 1d20 is only 5%. This has a distorting effect, particularly with Strength where damage bonuses go as high as +25% (for daggers and such that deal 1d4 damage).
OD&D has a schema hidden within it. Constitution gives -1 hit point per die (d6) at 6, and +1 at 15. These are the same distance, 3 units, from the median range of 9-12. Dexterity gives -1 to hit with missile weapons (d20) at 8, and +1 at 13. Again, these are equidistant from the median range. This is an interesting rule of thumb, and I think it's a good one for Blue Book.
So, Wisdom can give a bonus to save versus spells, just as in Moldvay, but it only gives +1 at 13 and -1 at 8. This gives Wisdom some role mechanically that it lacks in Holmes.
Strength is a thornier matter. If we have it give bonuses to hit and damage, the logical places are for a bonus to-hit at 13, a bonus to damage at 15, and penalties at 8 and 6, respectively. The difference is that 13 Constitution doesn't already grant a bonus, and 8 Constitution gives no penalty, so it seems fairer to move the second bonus 1 unit further away: +1 damage at 16 Strength, and -1 at 5.
My rationale behind this is the observation that Holmes fighters are way underpowered compared to Moldvay fighters, due mainly to strength, but I don't care for either the Moldvay or Greyhawk strength charts. Mine is simpler, and fits right in the sweet spot for me.
One of my least favorite additions is Greyhawk's modification of Armor Class by Dexterity score. It actually was supposed to represent an active parry, and only apply versus one opponent per round. But this addition wound up changing the definition of Dexterity; it stopped being a measure of hand-eye coordination and nimbleness of fingers, and became a measure of general agility. That doesn't really make sense, though; the two aspects are not firmly linked, and it's not a coincidence that Caltech's Warlock rules added Agility as a separate ability score. D&D never followed suit. But I'm not for using Dex to modify AC.
(This is one of the reasons I like Blue Book conceptually; it's easier to add than to subtract, and since Blue Book assumes Holmes, I can get rid of Dexterity bonus to armor class just by not adding it in the first place.)
Which leaves Charisma. Holmes says that Charisma is supposed to modify the reaction roll. OK, great! But how? He doesn't say. Moldvay actually breaks from his standard here and gives an OD&D-like +1 for 13-17 and +2 for 18, with corresponding -2 for 3 and -1 for 4-8. This is the one place where Moldvay ability scores actually go along well with the dice roll type, since +2 on 2d6 is a very significant boost.
Now, that's a lot of thought to give a few ability score bonuses. But I really think it's worth figuring it all out. As I've run a good bit of older D&D, I feel like Blue Book D&D is really very close to what my sweet spot is for the game rules, and it's really a question of tuning all the elements so the game works just like I want it to.
I would simply use a flat +1 for 13-17 and +2 for 18. As long as you are using 3d6 for ability scores, then its rare to have anything that really gives that incredible +2 and, at such a rare instance, it doesn't disrupt the game. To further that concept, it also gives more significant meaning to magic items or spells that grant an 18 ability score.ReplyDelete
Where are you getting the thing about Dex representing parrying and only applying to one opponent?ReplyDelete
Also, the Charisma modifier in Moldvay is 1/2 rounded up of the regular modifier. That formula can be used for other ability score modifiers when applied to 2d6 rolls. The normal unhalved Charisma modifier is used to generate the number of retainers and retainer morale. So it exists but isn't listed.
The original rule in Greyhawk is "Fighters with a dexterity of greater than 14 can use their unusual manual dexterity to attempt to dodge or parry opponents' attacks. For every point over 14 they are able to reduce their opponents' chances of hitting them by 1 (5%)". So it does representing dodging/parrying, but the plural "opponents" makes me think it applies to all attacks. But it sounds like it should affect the attack roll, not AC.Delete
Since Holmes has a parry rule, to integrate this rule you could simply give fighters a parry bonus based on Dexterity.ReplyDelete
