Shadowbane said:My character has a rogue blade (Savage Species). nearly all of my attacks are sneak attacks, no matter what.
hamstring sounds great, though.
With hamstring, you give up +2d6 of your sneak attack and it automatically reduces the foe to half speed until they get a cure spell. I had a rogue that used it for getaways instead of killing the guards.
If you are more about doing damage, I hate to state the obvious but two-weapon fighting is the way to go. An extra attack that's a sneak attack doing +9d6 is well-worth it. The big downside to this is that it requires a full round action. Which means you are next to your foe. From person experience that is bad.
A greater invisible rogue attacked my 18th-level dwarven defender. He hit on like 3 of his 6 attacks and did gobs of damage (150+), but not enough to kill the dwarf. The dwarf had blind-fighting and turned around and killed the rogue in a single hit (a heck of a crit with a warhammer). The lesson here is be sure to kill whatever it is you are fighting, or your likely low hit points are going to doom you.
