N/A

Missing more than one word:

The only security against a bad guy with a blade is a good guy with a blade

Suggested replacements:

"Security can only be ensured by the blade, and the willingness to use it."

"The only certain security is a good blade, and the ability to wield it."

"The security of the wielded blade trumps the feeble security of quill and ink."

...and, for the ironic among you:

"Blades don't kill people. Badass ninja assassins wielding blades kill people. Have a nice day."

On the 'pick your free bonus' screen from levelling up a tier 4 fortress to level 5, the Great Arena still has a reference to Prestige in the description text.
