Aion Guide Templar

Once you choose to be a Templar, you should try to move yourself as close to your enemy as possible and absorb their attack. If your allies would be those with ranged attacks rather than rangers or assassins, it would be very easy for you to do this. The Templar also get many passives in addition to the many skills that would inflict damage and provoke hatred in the enemies so that they would attack you first. This is very good for you teammates because they could attack the enemies without being attacked.
However bear in mind you would be the first to die in your group. The victory would go to your side just because of your sacrifice. As you play more and get familiar with various roles, you would know how to provide the most efficient support. Knowing this is very important, because you also need help from the healer. Your goal is to stand the attack, but not to die. Knowing when the healer would heal you would perhaps save your life, and your gold as well.
