Singularity can affect enemies through terrain even if it hits the wrong side of their cover however this effect while useful is somewhat unreliable. Finally, Singularity can occasionally fling enemies away from its vortex in random directions, while Pull will more reliably hold enemies helpless for its entire duration. Having Pull as a second option for holding enemies is very useful since casting Singularity again collapses an existing one. Pull can also execute a faster combo with Warp. When comparing Singularity and Pull, Pull has a faster cooldown and a faster projectile, both of which can make a big difference especially against multiple fast moving enemies that could outrun Singularity. Since Singularity stays in place and be used to capture several enemies, it can also be very cooldown efficient. Singularity is an extremely powerful tool for crowd-controlling many protected enemies, which are repeatedly staggered by it (including dangerous enemies like krogan, Harbinger, Scions). Singularity has a large area of effect and can be placed like a mine to capture multiple charging enemies, but it does not hold enemies as long as Pull. Powers Class powers Singularity Main article: Singularity Since protected enemies often come with unprotected friends, however, an Adept is hardly useless, just not as impressive. This forces you to rely on your squadmates or your weapon damage to whittle down protected enemies, only using biotics to finish them off. The mechanics of Mass Effect 2 were changed so that an enemy with any form of protection cannot be controlled, and biotic abilities are very bad at burning through shields. The Adept does come with a significant drawback with regard to shields (and to a lesser extent, armor). The Adept is indeed the best class for killing enemies without firing a weapon, but since you have weapons, why not use them? While your starting weapons are not impressive, you can take on additional weapon training later, and on a second or subsequent playthrough, you may choose an ammo power to complement your biotics as well. When combined, these abilities can wade through unprotected targets allowing very little return fire. Shockwave works as a bit of both, doing moderate damage and knocking targets off their feet for a brief period. Warp was also changed from a debuff/denial of access into a straight damage power to complement Throw and to provide options for damage abilities. It still has the same crowd control ability, but that ability is now condensed into two powers: Singularity and Pull. The Mass Effect 2 version of the Adept is more streamlined than the Mass Effect version of the Adept.
