I can "shoot" the spell at an enemy, but in 90% of the cases it doesnt seem to jump to anyone further and just hits the one enemy...is there any condition for a jump to occur? thanks!

You should have to at least graze the enemy, I'm not sure tho if it can proc on misses.

so that means as soon as i miss it stopps jumping further therefore? Cause the spell description doesnt mention this

But it is

It does keep bouncing if you miss, actually. Other things can stop it bouncing though, the most likely being that the current target gets killed by the Mind Blades. It only keeps on bouncing if its most recent victim survived. It can also be stopped by a lack of valid targets in range (although Mind Blades has long bounce range; it doesn't hit anyone twice though). 

 

Edit: damage also decreases by 10% for each bounce by the way. This is cumulative, so 90% damage on first bounce, 81% on the second, etc. (this is handled like any other X% damage modifier).

It's true - if the target dies, the jumping stops. It's the same for all "jumping" spells.
