Mesmer Clones
I wouldn’t count on your clones for producing any real damage unless you trait into Sharper Images to at least let them bleed. My clones at level 80 do I think 16 or so damage on a crit. I really miss BWE 1 clones when they could do better damage.
Clones are for confusion and shatter damage. They have no direct damage.
So the answer is never.
Phantasms are the ones that do damage.
For reference, even at level 80, your clones do a meager 10-15 dmg. Clones serve two purpose (1) distract the enemy (2) used for shatter skill. They will not cause any real dmg themselves.
On the other hand, if you want to summon illusions for DPS, instead of clones use phantasm (the ghostly white ones). At low level I’d say start with Pistol Phantasm, good dmg, stay at range so it wont die, and looks cool.

Check the traits that enhance clones here. You can get an idea of what you can do with them. They can also be somewhat tanky if you play a support build.

Staff clones can actually do quite a bit of condition damage with Winds of Chaos and sharpen images.
But yeah, clones are mostly fuel for shatters and to distract some people.

The only clones that really -do- anything are Staff, Trident and 1h Sword, other than that you wanna use them for shatter fuel.
