[2nd wave progress: 10%.]
Once the monster waves ended, the monsters that were still on the field did not just disappear like it was some game.
It was not the case even in the Tower of Beginning. Even in that game, the monsters stayed, and the players needed to fight each and every one of the monsters, preferably kill them during the wave itself.
If they failed to clear out the monsters during the wave time, the next wave of monsters would start, and they would have to fight the new monsters alongside the older ones that were still on the field.
The traps, thus, were as important as a second life in the games.
They not only blocked the smaller and weaker monsters, but they were a barricade that prevented the newer, smarter monsters from abruptly charging into the battlefield.
