A EP Drop is either items such as Ancient Statuette, Saradomin Statuette, Statius's Warhammer, Vesta's Longsword. The more EP you have, the better chance of getting one of these drops are if your opponent isn't risking one. To gain EP, you must stay in the Wilderness without dying for a long period of time. The longer you stay, the higher it goes. The deeper you are in the Wilderness, the faster it goes up and stops at 100%.
