Completed 3 hero challenges in 3 matches today (Nyx, Drow and Clinkz). Pretty happy about that. Next up is Disruptor and Bane, both of whom I'm 0-3 with. Might have to look up a guide because whatever I'm doing isn't working.
Here's how you win with disruptor. Save your first skill point. Glimpse at level 1 is normally a shitty spell, but in the right situation it's going to be worth way more than the damage from Q or the control from E. He isn't too useful in lane, so go pull to get your early levels. Have a point in each skill at level 3, then max glimpse, then max E. The way you get easy kills with disruptor is using the travel time on glimpse to set up the ult/E combo. You'll see a little mark on the ground where the person is going to return. When you use your ult, you need to immediately E afterwards on the same exact spot. The radius for both skills are about the same, and the static storm will cover the entire circle.
The Q skill does shit damage but is hugely important because it gives vision. You use this vision to cast glimpse no matter how far away that person runs. Even if it's someone like antimage or qop, they can't blink far enough away to get out of glimpse's range when it has 3 or 4 points in it. Disruptor is one of the best heroes in the game at ganking these types of heroes. An easy way to know exactly where the opponent will return when using glimpse is to cast Q on them, and count the strikes in the animation. On the 3rd strike, they'll return to the place they were when you cast the Q on them.
E gives vision, so you can use it to deward a cliff in a pinch. Disruptor's entire skill set because useless once BKBs are out, so later on you want to be casting it on the supports or bkb-less carries. Unless you are using it to initiate by pulling someone back with glimpse or really need it to catch someone in the ult, try to save it if you can. It's an amazing spell for getting one more kill out of a successful team fight.
It can be a bit awkward at first because his skills take some foresight to use properly, but he's such a fun hero.
