All I want to know is how to get past ten floors without Gengar dying. I'm in Murky Cave. I'm a level-58 Venasaur with Leech Life, Vine Whip+3 (+ any number shows how many times the power for that attack have grown without level-up), Razor Leaf+2, and Solarbeam. I've tried adding more team members but his ability to pass through walls leaves them behind and wastes time. What should I do?
