Here's my suggestion in a nutshell: Perhaps we could go with a universal key of statistics for creatures (and everything else) in the game? Then individual listings would only need to account for and list relevant stats to get rid of excessive redundancy and cross over. For example, the following could be a Monster Manual (MM) listing because it is referring to the entire breed of monster:
[sblock]Name (genus, family, order, etc.)
SZ: Size (S,M,L) with option to further define (i.e. 6' high, 19' wingspan, reach)
MV: Movement Rates (standard is on ground) Swim, Fly, Webs, Climb, etc.
AC: Rating with components
HP: # of hit points; HD: # and type
AT: #, type, and damage
SA: (special attacks / feats / powers / spells)
SQ: Special Qualties, like auras, blinking, darkvision, etc.
MR: Magical Resistance, immunities, etc.
AS: Average Ability Scores for the monster S 10, D 10, C 10, I 10, W 10, Ch 10
AL: alignment; (optional) ML: Morale; LO: Loyalty;
FQ: (optional stat)frequency, No: Number Appearing %L Percent in lair
TT: Treasure Type
XP: XP rating[/sblock]All Spells Known could then be treated like Treasure, listed under a separate paragraph to track for individuals, groups, and changed as events unravel.
These "Master Stat" entries are useful for reference to common and unchanged statistics across all a unique monsters of a single breed. Plus, these would allow for already averaged mass scale actions by the same creatures . (Maybe we'll see "Any weapon" or "Finesse weapons" in the MM spread with averaged damage? Perhaps we'll see mass actions whether it be battles, commerce, migration, politics, or something else?)
Individual monster stats could then be shortened considerably from this MM entry, but extended with its own stats unique to each individual monster. (Unique stats would also need to be defined in the DMG or MM). For example, the monster and NPC stats in Caves of Chaos have been wonderfully short. (thank you). By supplementing the unique monster in the text with the overview in the MM (as desired per DM) I can get everything I need to run any element of the game that includes creatures both quickly and easily.
[sblock]Name (Monster, Race, and/or Class), MV, Init, AC, hp, AT: (and damage), SA (unique), SQ (unique)
AS: "Name"'s particular ability scores.
PP: (optional stat) psionic powers and/or spells prepped.
EQ: Equipment and magic items on hand.[/sblock]Listed seperately are Spells Known, in a spellbook, not prepped, along with property not on the person (granted authorities and the like).
Special Abilities each get a detailed entry too.
So... the Hooked Horror would look something like this:
[sblock]Hook Horror (Magical Creation, Kaomeister)
>> Source (White Dwarf #12, Fiend Folio, Dragon #131)
SZ: Large; 5' space, 10' reach
MV: 30', Climb 30'
IN: +1
AC: 17
HP: 60 (HD & type?)
AT: (Melee) 2 Hooks +5 (1d10+4 pierce & impale); the hook horror cannot use a hook to attack if a victim is impaled on it
SA: Impale, Twist and Bite
SQ: Echolocation
MR:
AS: S 18, D 12, C 15, I 6, W 12, Ch 9 (or S+4, D+1, C+2, I-2, W+1, Ch-1)
AL:
FQ:
TT:
XP: 450
Two hooks +5 (1d10 + 4 piercing, and impale); the hook horror cannot use a hook to attack if a victim is impaled on it
Impale An impaled target can escape by using its action to succeed at a DC 12 Strength check.
Twist and Bite Any creature currently impaled by the hook horror takes 1d10 + 4 piercing damage. In addition, the hook horror can automatically bite an impaled creature for 2d6 + 4 extra damage.
Echolocation A hook horror ignores anything that obscures vision within 120 feet. A creature can attempt to hide only if a physical object completely obscures it from view. It can remain hidden as long as it remains behind such an object or ends its turn behind one.[/sblock]And the Adventure Modules statblock:
[sblock]Avon Calling (Hook Horror), MV 30' Climb 30', Init+1, AC 17, 60 hp, AT: 2 hooks +5 (1d10+4 pierce & impale); SA: Impale, Twist and Bite, SQ: Echolocation
AS: S 18, D 12, C 15, I 6, W 12, Ch 9[/sblock]Ability Scores are unchanged, but pretend I rolled them up for this guy in particular. PP & EQ are left off as both are "none". Redundancies like the entries for SA and SQ are kept in because Avon here could lose those abilities even though all Hook Horrors may not. I'd say repeating a detailed listing of special abilities isn't necessary either (so I didn't), but it's probably up to the individual / publisher. SA's unique to Avon Calling would definitely need to be included.
