which is dex based...
i've also found with a high dex character, that even if you get hit, you hurt less with high dex...
to find out exactly what is happening with attack rolls and etc, go to the menu where you see dialogs, then press "x" button to see the exact attack rolls and results...i've noticed that sand people have very high attack ratings, and hit you more than others...and rancors have huge attack points...that screen is where you find out the exact numbers...
here is the infamous str vs dex argument...
a bonus in str will give you attack and damage bonus...
pro: kill them before they kill you, and early on in the game, crummy weapons will still do respectable damage...
con: load up on medpacks and exploit the infamous pause/heal cheese, cause every yahoo on the planet will hit you...(when you get hurt in the middle of battle, press start, to go into the menu...now go to inventory screen, not your equipment screen, scroll until you see a medpack, and press the green button to use it..you will see when you return to the battle that you've been healed, and you did NOT use a combat action to heal yourself, so you can still cast a force power, or attack that round...
a bonus in dex will give you attack and defense bonus...
pro: later in the game, you meet some very tough customers indeed, and you have access to some very powerful crystals...so you will do more damage than before, with better weapons...
and your defenses are better, so you're going to get hurt less often...even against rancors, they will sometimes miss you, which is always a good thing...and even if you get hit, i think a good defense will thin out some of the damage...
there are some major str boosting equipment in the game...
con: your attacks won't do as much in comparison to a jedi with identical equipment, but high str.
generally overall, i believe a high dex will offer better survivability...and less frustration..
a high str character is better for powerusers and people who have run thru the game at least once, so they know what to prepare for, and have a good strategy in place before creating the high str jedi...
