HAY U!
I came up with an idea while in FSC today. Combine the Black Kat Cowl with CIV for Max DI vs Undead. This also works with Wild Hunting Blade, Heavy Deconstructor, and Cautery Sword. So, why use these over specialised weapons anyway? Because you can, duh. I have in my mind some challenges for y'all.
Common rules:
You should wear the Black Kat Cowl. Sorry, Zeddy and Quakeman! D=
You may not change any equipment after entering the first floor with monsters.
You may not use any weapons but Cold Iron Vanquisher, Wild Hunting Blade, Heavy Deconstructor, and Cautery Sword.
You may only fight Undead with Cold Iron Vanquisher.
You may only fight Beasts with Wild Hunting Blade.
You may only fight Constructs with Heavy Deconstructors.
You may only fight Slimes with Cautery Sword.
You may fight the remaining two monster families with any of these weapons.
Skolver clones do not fall under the Beast family.
You may not wear any armour that gives any non-family specific bonuses (e.g. you may wear Valkyrie but you may not wear Snarbolax or Volcanic Demo), the Black Kat Cowl and Mercurial (the regular version) being the exceptions.
You may not wear Swiftstrike Buckler or Barbarous Thorn Shield.
You may not wear any trinkets that give you Damage Increase, Attack Speed Increase, or Charge Time Reduction for anything.
You may not wear any trinkets that increase your health.
Clarification: you don't NEED all those four weapons but they are the only ones you may use. If you say, have no Cautery Sword but encounter a Slime family monster, you can fight it with something else.
Multihits with say, the Decon, is okay as long as it hits a construct. This applies to all weapons.
Because I do realise not everybody has the Black Kat Cowl, it's now allowed to use helmets following the same rules as Armours.
UVs are perfectly cool on weapons anything.
Just for fun, I will give 5,000 CR to the first person to do Dauntless Hipster and uploads it to YouTube. No guarantees here due to possible lack of clarity that might put two parts in disagreement. I will NOT accept speedruns, though. Try to fight all monsters if you want these barely botherable crowns.
Now, for the challenges themselves...
Sounds fun, except for the fact I don't have those weps.
