I think one holy trinity my group had was the combination of a short sword of speed, with a longsword, both with high pluses (+3, +4) and a girdle of giant strength or ogre gauntlets.
You could hit three times in one round and the penalties didn't matter that much on the to hit with all those pluses. Routinely did over 100 hit points per round. It is why I jokingly said the wizard will win a ranged battle but if the fighter is close and wins initiative he will drop almost any class in one round.
Three attacks doing 100 per round means over 33 hp per hit. Gauntlets to Storm giant girdles give +6 to +14 damage on a hit. +4 weapon with +2 specialization would be +6 more so that would be +12 to +20 damage on a d8/d12 longsword and a d6/d8 shortsword.
Anything I am missing?
Short sword of speed only showed up in 1e Unearthed Arcana and only gave first strike in a round, not extra attacks.
Sword, Short, of Quickness is a specially dweomered blade that enables the wielder to strike first in every combat round. It is also a +2 magic weapon, with the bonus applicable to both hitting and damage.
In 2e there was the scimitar of speed which gave an extra attack
Scimitar of Speed: This is a magical weapon, usually of +2 bonus, that automatically grants its wielder the first attack in a melee
round, even though some magical effect might have otherwise slowed his speed and reaction time. It also allows more than one
strike in some rounds, increasing the wielder’s figure for attacks per melee round by one place, so that if one attack is normal, then the improvement is to two attacks per round. This increase in attacks is cumulative with any other bonus attacks (such as those provided by a haste spell).
The order of attacks in the round is determined normally after the wielder of the scimitar of speed has made his first attack to
begin activity in the round. It is possible, for instance, that a wielder entitled to three attacks in the round will attack once before any
other action takes place, and then (because of poor initiative rolls or other factors) take his remaining two attacks at the very end of the round.
There is a chance (25%) that the weapon will have a bonus of something other than +2; if this occurs, roll percentile dice and refer
to the following table to determine the appropriate bonus:
D100 Roll Type XP Value
01–50 +1 2,500
(normal form) +2 3,000
51–75 +3 3,500
76–90 +4 4,000
91–100 +5 4,500
The best I saw in my long running 1e AD&D campaign was a drow fighter PC (fallen ranger) with the drow two weapon fighting to allow short swords, double specialization in short swords (so +3 damage) two magic short swords, and a girdle of hill giant strength (+7 damage instead of the +0 from his reduced 15 strength). So damage of d6s with +10 plus magic sword bonuses (highest was +3, the other was less) on multiple attacks a round. I believe I allowed the offhand to give one extra attack.
The Girdles are huge on impact regardless of anything else.
