Dishonored has several major elements that combine to create its unique gameplay: mobility, powers & gadgets, environment, and AI. The trick is that a single power doesn’t just do damage or heal you. You can combine them organically to create interesting effects. Stop time and knock a bunch of stuff off a table in one direction then book it in another, so the guards search for you in the wrong place. Summon a swarm of rats to attack one guard, but possess one of the rats and escape in the chaos. Every problem has as many solutions as you want it to.
