Final Fantasy XI Black Mage
The offensive nature of the Black Mage comes in many forms beyond simple nuking. You need a good understanding of a monster's elemental weakness; you will know FFXI Gil is important in the game and how to boost your effectiveness in dealing elemental damage, enfeebling and ending skill chains. Skill chains are a series of weapon skills that when done in order, generate large amounts of damage against a target and at the end a Black Mage must know what spell to cast to match the appropriate skill chain in order to create a magic burst. A magic burst posts some impressive damage numbers and closes the skill chain. Another skill set is learning to exploit the elemental weaknesses of a monster type and is a skill every Black Mage should try and learn.
It means that the difference between a spell barely scratching a monster and them getting rocked by the full power of your wrath. You will become more and more dependent on gear swapping to increasing your abilities to exploit that weakness and increase your damage dealing capabilities as long as you progress. To learning how to squeeze the most damage out of a spell, its flip side is learning how much is too much. The last thing you want and can make life hard on everyone else in your party is pulling aggro. If the tank uses up all his tricks saving for you and then the mob turns on your heals, a trigger happy Black Mage is able to get everyone killed. Between love and hate, you must learn to control your damage dealing abilities and walk the fine with your nemesis. It is a chance of death and your steps determine whether it is them or you that die in the end.
