For all the newcomers to Crush Online, welcome! I just wanted to point out that when you're in a NPC territory (neutral zone/Grey area) you don't want to waste the TP on minions or mines or whatsoever. Talk with the people in your map. The goal is to reach either 10,000 TP or beat the boss. Currently lv 1-3 is possible to kill within a couple of minutes. Lv 4 takes around 20 minutes with a good group. Lv 5+ takes longer but needs coordinated group. The only useful usage for strategic skills are the portal, recovery shot for these types of areas if you plan on killing the bosses. That's all and please don't make it into an endless grind. Make sure to communicate on what to do with your group of people within the map.
