What does this even mean? --> 60/110/160/210/260

That is a frightening amount of context you've put your question in. You realize thread titles are supposed to give an idea of what your post is about, and your post is not only supposed to have the majority of your question/discussion starting material, but it's actually supposed to have stuff written in it, right?

I would assume the damage of an ability as you level it up

Level 1 60 damage Level 2 110 damage Level 3 160 damage Level 4 210 damage Level 5 260 damage
