There seem to be doubters in our midst. Very well, let me get Newtonian on
your collective asses.
Firstly: something wielded "with ease" is not the case for any uranium weapon
with a mass over 25 kgs. It is not possible for any mortal in the game, even a
titan, to 1h those without a forceiwld penalty. I think it is fair to say that
you can't swing a weapon very fast if you're struggling to even lift it! In
addition, the number of heavy, pure uranium weapons is fairly limited, which
is kind of strange -- heavy weapon hit hard, and uranium is durable.
But, let's go on to the next problem: the required speed. Of all the uranium
weapons over 25kg, the great axe is technically the fastest. Without any form
of magic or boons, it takes about 5 seconds to swing a great axe two-handed in
combat. Let's take our largest race, a titan, using the axe. To get the axe to
go from 0 to 300meters per second, in five seconds, requires 1800 Newtons of
force -- enough to dead-lift about 183kg -- and assuming nice, clean, constant
acceleration (which in turn requires the minimum force) you'd need to spin
around in a circle at least 25 times to get up to full speed. That requires a
str of at least 266, and some pretty impressive dex to spin 5 times a second
(this is an Olympic-quality performance by an ice skater with nothing but
spandex, let alone a 30kg axe). 266 str is do-able, or you could use a skill
which takes more time (and therefore less force), but there are other issues.
A titan probably doesn't have arms 3 meters long, and the axe probably isn't
two meters long, either, but the bigger the circle, the less the centrifugal
force, which is about to be a real issue. See, a 30kg axe spinning in a 4m
radius circle at 300 meters per second requires 270,00 Newtons of force to
keep from flying out of your grip and off into the sunset. Even if you could
convince yourself that your character's grip strength is 100 times their
normal strength (maybe you have the feat "hands of glue" or something), you
would need a strength of 450 to keep your grip, which is asking quite a lot
indeed -- a very strong race with a very good +str set might be able to do
this.
Let's pretend, somehow, you get past the grip strength issue also. You have
the strength of 8 men and can spin like a helicopter. Now comes the hard part
-- something to hit. 25kg is only HALF of critical mass -- you need to slam
your weapon into someone else's shield, or armour, or parrying weapon, who
also thought it would be a good idea to use a ton of U-235. Lodes in the
ground definitely aren't that pure (ask any merchant), and even if you find a
uranium statue or fountain, odds are, its quality sucks. So you're either
going to find a monter worth at least 300k exp for the necessary str and dex
who happens to wield a piece of uranium eq, against which you can land a solid
hit (this rather limits your options) -- or another player who's just as
morbidly curious as to what will happen, and also has the epic strength and
dexterity you do, and willint to sacrifice their top-of-the-line +str set in
the explosion they're about to be part of.
