Fire Mage
For a very precise formula on calculating fire bolt damage, please refer to Swan's thread:
http://celtic-heroes.com/forum/viewtopi ... 49&t=55462
The basic spells for the standard fire mage are: Fire bolt, fire storm, fire attunement, fire lure. You will want to max fire bolt, fire storm and fire attunement for good DPS. For the fire lure, you will want it to be at around half of the max points you can put in the skill.
For example: From levels 180+, your skill max is 40, so lure should be around 19-21. From levels 150-180, your max is 35, lure = 17 or 18. From levels 120-150, your max is 30, lure = 14-16. Levels 90-120, max is 25, lure = 12 or 13. Levels 60-90, max is 20, lure = 9-11, ect. NOTE: This goes for lure of ice as well, if you are going for an ice mage build.
With left over points, you can either place them into energy boost (more energy regeneration for longer fights), energy shield (more survivability), other lures (to support your group) or into other damage spells to maximise your DPS, such as ice shards or incinerate.
NOTE: Damage over time spells such as frostbite/incinerate are more appropriate for longer fights (boss fights)
I don't recommend cloak of fire for a fire mage build, because enemies that cast skills will not be effected, and you need to place it on whoever is being attacked, which can be confusing at times. The damage cloak of fire provides is also seen not to be worth it.
As an example, a level 90 fire mage will be looking at this sort of build. Assuming they have a little bit of support in mind:
Fire bolt: 25/25
Fire storm: 25/25
Fire attunement: 20/25
Fire lure: 12/25
Lure of assassins: 7/25
Energy boost: 6/25[/i]
