More damage than any other class once you gain more levels
I assume you mean with unarmed strikes, i.e, the d20 damage.
Alright.
Assuming the monk puts a 14 in strength to begin, and buys a
girdle of giant's strength +6, he has a 20 strength, for a +5 strength bonus to damage. Add the
amulet of mighty fists +5, you get a +5 enhancment bonus to damage. Is there anything else to pile on? Monks aren't my strong point. Anyway, that gives 10.5 base + 5 strength + 5 enhancment for 20.5 average damage per blow, or 41 on a critical hit, with a 19-20/x2 threat range. It should be noted that the monk, even though he has more attacks per round than the fighter, will, on average, hit fewer times, because of his 25% worse BAB.
Okay, now the fighter. Assuming the fighter put a 16 into strength to begin (fighters don't have to worry about nearly as many stats as monks, so we can have a higher strength score), and buys a
belt of giant strength +6, puts 4 of his 5 attribute points in strength, and buys a +5
icy burst flaming burst keen falchion, does 5 base + 12 strength + 5 enhancment + 2.5 fire + 2.5 frost for 27 damage, or 43 on a critical hit, with a 11-20/x2 threat range.
Now the wizard. The wizard has Spell Focus (Transmuation), Greater Spell Focus (Transmutation) Spell Penetration, Greater Spell Penetration and Heighten.
The wizard starts with 18 int (I play 25 point buy and this is easy to do), puts all of his level bonuses into int, gets a tome of int +5, and a headband of int +6, for 34 int. He also casts an
empowered empowered empowered empowered fox's cunning on himself, using a
lesser rod of empowerment, for an average +10.5 to int that does not stack with the
headband That leaves his int at a healthy 38.
He Heightens a
flesh to stone to 9th level, and casts it at your monk. DC 39, with a +24 bonus to beat spell resistance, vs your save of 12 base + 5
cloak of resistance + 5 constitution bonus. The monk needs a 17+ to save, while the wizard only needs a 6 or higher to beat SR. Doesn't look so good for mr.monk.
Who's more damaging again?
