-_-. As for leveling up, the exp caps at about 70,000 after 15 minutes. So you can't leave your game on for a whole day in hopes of getting a million exp. xD Just let the MC smack these guys around for a good 20 minutes and he'll level up 2-3 times. It's guaranteed the best way to level up in the game.
tanÂ·gent. n. 1. Mathematics. a. A line, curve, or surface meeting another line, curve, or surface at a common point and sharing a common tangent line or tangent plane at that point.
A tangent is an entirely different topic or direction. When you want a break from geometry class, you might ask your teacher about his hobby of woodworking, a topic that's always good for a ten-minute tangent. Tangent is mainly a mathematical term, meaning a line or plane that touches a curved surface but doesn't intersect it. The non-mathematical meaning of tangent comes from this sense of barely touching something: when a conversation heads off on a tangent, it's hard to see how or why it came up.
