How long did it take you guys to get to level 100?
I have been leveling once every attack run, and I do three to four runs a day, so if the rate stays constant, I figure I will be a power house in about a month. But I am sure that at higher levels it takes longer to level.

A long time. For us there weren't many players so it took a long time.

Bone has got to level 100 in like 3 weeks. I don't kow how he does it.

My suggestion: keep at it and only then will you be a powerhouse

At the beginning you only have 4 attack making it harder to gain level.Once you get enough attack try and attack everyone that you can.
at your speed you'll get to level 100 in like 1 month. Level isn't important. Your stats is. (My stats is more than fishfly but my level is below him. So my level + stats is more worth.)
