Psychoincarnate i dont think he asked to explain it physically , speed more likely gives a faster opening to attack an enemy ,better hit rate and avoidability.
also, If I remember correctly, the higher your speed the higher your physical piercing. (Certainly did a few thousand damage usually WITH Shadow Blend)
Heat_x, vicious strike, sample blood, and slash all use a very good chunk of speed when determining damage, that is why shadow blend+sharp senses+speed equips+one of the above attacks make for one of the strongest nukes in the game.
Anyways, speed determines whether you go first as a team, and who goes first on your team as well as determining your chance to dodge enemy attacks and your chance to miss on your own attacks.
It might also affect your critical rate, but i'm not sure.
speed is a 1 sylable word created by some kind of dude who wants to represent "speed"!hahahahahahahaha!!!!!
nah..actually,speed increases your accuracy,chance to dodge and it allows you to strike first.if you have too much,you attack the enemy 2 times.for me,i depend on speed not to vitality,etc,etc,etc.....
Depending on speed over vitality is kinda risky. Sure if your a speed based physical bio that means that you'll be hitting extrodinarily high with shadow blend on, but if an enemy gets one good hit on ya, you could die.
Speed increases the chance of the enemy missing and decreases the chance of you missing. On a scale of 1-10 I think speed is 6/10-Kind of important to have.
