Creating a sort of early warning system is one of the best tricks you can use to avoid being caught off guard by the other factions. This is quite easy to implement: you simply create a chat tab and then set it to display enemy combat spam. In a world you can have any warning you want get, especially when it announces an Assassin used hide. I as an aion player set the text to some nice red, yellow, and orange colors, according to my personality. Moreover, I also go ahead and set the enemy death there as a bright green color. The advice to you is once you have your tab, you are suggested to put it somewhere you can see it easily while going about your business.
There are two very good advantages this chat tab provides. The first one is: combat spam has a long range than your radar. You will see it one your chat tab, you won’t know which specific direction it is in, but you will know the enemy using. This is very valuable, because it will give you an idea of the level of the foes in question. General speaking, in the case the ranks of the basic skills being used are higher than the ranks of yours, then the enemy is probably a higher level, which in turn means they will have a big advantage over you.
