Now we provide the following weapons to your PCs.
(A): The first time you hit a foe on your turn, this polearm deals +4d12 damage. If you have advantage, this weapon criticals on doubles.
(B): This +3 longsword causes the target to be vulnerable to radiant from its attacks.
(C): This +3 greatsword adds 1d4 cold damage to every hit.
(D): +3 polearm
(E): This is a greatsword. It has no properties.
There is a baseline 60% hit, 5% crit chance; the +3 weapon has a 75% hit chance instead.
Longsword is 1d8+2 (dueling) for fighter, 1d8 for other
2 handed sword is 8.33 for fighter, 7 other
Greataxe is 7.33 for fighter, 6.5 for other
20 attack stat, except barbarian who has a 24 (so +2 to hit as well).
The fighter over 3 rounds gets 20 attacks. At baseline accuracy that is 13[W]+12[C], where S is static and W is "weapon" damage dice, and per action has a 2.6% chance of wiffing completely. Careful use of action surge should reduce that to 0. The first hit has a 5% chance of critting, so weapon (A) deals 12.6d12
E: 13[W] (8.33) + 12[C] (11) = 240.29 damage
D: 16[W] (6.3) + 2.4d4 (3) + 17.25 [C] (11) = 297.75 damage
C: 16[W] + [C]15 = 10.83*16 + 11*15 = 338.28 damage
B: 16[W] (4.5) + 15[C] (10) = 222 damage
A: 12.6d12 (6.5) + 13[W] (6.3) + 2.4d4 (3) + 13.8[C] (11) = 322.8
The +3/2d6 cold greatsword dominates for this fighter.
Lets try the barbarian! +0 weapons is 91% hit chance, 9.75% crit chance.
Chance of wiffing with a +0 weapon is 0.81%. I'll treat that as 0.
They get 6 swings, so 5.46 hits and 0.585 crits, for 6.045[W] + 5.46[C]. is 17 for 2 handed weapons
With a +3 weapon accuracy is 97.75%; 6.45[W] + 5.865[C].
For (A), your crit chance is .05 * 19/20 + 0.0975 = 0.145%, is 17, [W] is 5.5, and you get 12*1.145 = 13.74d12 bonus damage.
1/20 of the misses become crits, but those are
5.468 hits, 0.87 crits, for 6.338[W] + 5.468
E: 6.045[W] + 5.46[C] = 135.135 damage
D: 6.45[W] + 3.225d4 + 8.7975[C] (20) = 219.4875 damage
C: 6.45[W] (9.5) + 5.865[C] (20) = 178.575 damage
B: 6.45[W] (4.5) + 5.865[C] (14) = 111.135 damage
A: 13.74d12 (6.5) + 6.338[W] (5.5) + 3.169d4 (2.5) + 8.202[C] (17) = 271.5255 damage
A different weapon is optimal.
Paladin's B is the only intersting one.
We'll use level 4 slots for smiting once each turn, and a holy weapon. So your [W] is 1d8+3d8 radiant.
.75 hit 0.05 crit and +10[C] .
Chance of wiffing is 6.25%, so you get 2.8125 smites per fight; of these, 0.140625 are crits, for 2.953125 smites worth of damage. Smite dice is 4d8 so 11.8125d8 from smites.
Over 3 rounds that is 4.8[W] + 4.5 with 4.8[H] hits.
B: 4.8[W] (31.5) + 4.5[C] (10) + 11.8125Smite (9) = 302.52125 damage
Plus this Paladin keeps their shield, worth at least a 4 point AC edge.
Damage per tap the fighter gets the most benefit from. Items that don't do that give benefits to other classes. And there is nothing against granting an item that boosts other classes relatively narrowly, like the vulnerable to radiant +3 longsword.
Fighter Charop is also far easier than other classes; Paladin Charop often involves multiclassing (often into fighter as well), and got worse in 2024.
