What does Requirements -nn do?

Deadly strike doubles damage, but does not work in conjunction with critical strikes.  Pretty much, you first roll for critical strike.  If that misses, you roll for a deadly strike.  Therefore, your 50% deadly strike on the weapon and say a 50% critical strike would not equal 100% double damage.  A simple (or complex) math formula can tell you what your effective % double damage really is with critical and deadly strike both on the same character, but it has to do with combinations or permutations and I dont care enough right now to figure it out.

For the overall chance of double damage, use any of these (they're mathematically equivalent):

CS + DS - (CS * DS)
CS + (1 - CS) * DS
DS + (1 - DS) * CS
1 - ((1 - CS) * (1 - DS))

(Of course, values should be in decimals, not percents).
