The luck bonus is part of Perfection in Bushido. To obtain perfection, you must Honor your opponent prior to engaging in combat. You can set up a macro in UO (not UOA) by going to your option gump for macros, selecting the "Use Virtue" & "Honor", then setting a 2 key macro (I strongly suggest a 2 key otherwise you'll end up accidentally embracing your hard earned honor due to a conflict with "last target"). Once you have this macro set up, it will bring up a targeting cursor (which can also be brought up by double clicking on the virtue gump itself from your paperdoll). Target the enemy, keeping in mind you must be within 6 tiles (2 if you wish to gain in honor), then attack your opponent. You will gain 1 level of Perfection per consecutive hit, but will lose 3 levels of Perfection for each miss. At GM Bushido, you receive 100 luck per level of Perfection, along with 10% damage increase (subject to the 300% DI cap). Perfection's highest level is 10, or 1000 Luck & 100% damage increase.
If you go to the Stratics main site, the Bushido page has been updated very recently (I updated it
) so is accurate with all Bushido information and changes to date.
Oh...almost forgot....if you're looking for a good bow, come see me. I'm in game now. I've got a whole pile of bows at my house so I'm sure we can get you set up with some nice weapons.
