Elder dragons are extremely weak to slime, so that's why you killed it so fast. Slime works on all monsters but certain monsters have some resistance. Brute wyverns tend to have some resistance, especially brachy. You have to learn about what monsters to use slime on and what monsters are better to use an element. Also, soloing with slime weapons isn't that OP because with 4 people using slime at once you will be blowing the monster up every 10 seconds, but soloing you don't have that.
