Help with the mage fire

Hello everyone, I am needing help with my magician, lately I am doing a 40k dps and then I go down to 20k and from there I can not go up, any recommendation?

I’d appreciate your help and be able to excuse my English.

Fire plays very bursty so it’s normal to see spike burst dps when combustion is up and then see it fall off when no cds are up. The current high dps build for fire requires a few core things: The essence Memory of Lucid Dreams for the neck piece, 3 pieces of Azerite gear that have Blaster Master Trait on them, at least one on use trinket, and ideally, the Hyperthread Wristwraps that drop in Mechagon or in Workshop keys. A good place to start would be to farm these pieces. Manifesto is a good on use trinket to start with as long as you remember to cancel the crit buff and roll straight into the vers buff during your burst combustion phase. To go more in depth a good place to start is the Icy Veins guide and for more detail on what corruption to take and why, go to the Wowhead website for more info
