Well, that's why the "Number of Attacks" entry is included; the two need to be looked at together, while understanding how attacks are handled by the rules. The main issue is that the existing books aren't that consistent, with Urdlen listed as "4d6 x2 (claw)" for his two claws, which I would always list as "4d6/4d6 (claw/claw)." On the other hand, Lurue is "blah x2/blah x2/blah x2 (hoof/hoof/horn)" which is much too clunky. Putting the x2 absolutely last might be best now that I've thought more about it.
Well if Number of Attacks were handled consistently in 2E we wouldn't be having this problem.
Early edition D&D's exception-based rules has many charms but ease of interpretation is not one of them!
Putting the ×2 last after a closing parenthesis was my preferred solution - as in "(hoof/hoof/horn)×2". I agree that sticking ×2 after each attack is just too clunky.
For monsters, yeah; however, gods don't always play by the same rules. Sometimes they get their Strength bonus, sometimes they don't, sometimes they get the fighter attack routine, sometimes they don't, etc.
Well it's not just AD&D's Gods that sometimes get their Strength bonus on non-weapon melee range attacks like claws in early editions, there are a few monsters that play by their own rules even in 1E AD&D. The Daemons from
Fiend Folio (1981) and Colchiln from
Mordenkainen's Magnificent Adventure (1984) are the earliest examples that come to mind.
The Colchiln was doubly confusing since according to its description in WG5 it has a Strength bonus ON TOP OF a +3 base damage bonus ["
strengths range from 18/01 to 18/00, but the creatures gain only the +3, +4, +5, or +6 damage bonus (add to the base ld6+3 points of damage)"] while its encounter in that module has a Dmg stat that is a bit sloppily phrased ["
Dmg 4-9 per claw, Str 18/75 but with no bonus to hit"], since it'd be easy to see that 4-9 and think the 1d6+3 is just 1d6 base damage and +3 for its Strength 18/75.
If it gets 1d6+3 base damage from its adamantine claws plus +3 for Strength I'd prefer "Dmg 1d6+6 per claw, Str 18/75 but with no bonus to hit" there.
Legends & Lore is the most inconsistent of all the books however; I try to base my stuff on what is in Faiths & Avatars, Powers & Pantheons, and Demihuman Deities. Because Neogi generally can't use weapons, I'll be giving the fighter attack routine to the ones who would be deadlier in physical combat.
Yes, the 2e god-books that came out after
Legends & Lore do become somewhat more consistent in presentation although there are still plenty of glitches - like Nobanion's Avatar in
Powers & Pantheons who's lion form claw/claw/rear claws/bite don't get ×2 attacks despite being a 23rd level paladin and 19th level ranger.
As you pointed out, Lurue in that source gets ×2 attacks as she's a 17th level ranger. One would think Nobanion would strike at least as quickly as the Unicorn Queen in melee. They're both Demipowers, and Nobanion has many more warrior levels than Lurue and is the "King of Lions and Strong Beasts" and a "Guardian".
