First of all, you ask this question, which shows that you haven't read your talent description and skill description carefully. Ignition is a passive talent. When your direct damage spells, such as Fireball, Inflammation, Burning, and Critic, 40% of the damage will become an extra 4-second point and 2-second jump, and the lighting refresh triggered by the crit of the new spell can be superimposed within the duration. This is the core talent of fire fighting. Constant crit can turn your lighting damage into extreme terror. When I was a freshman in well of eternity, the maximum lighting was 10W. Therefore, the benefits of fire crit are very high, and of course, the rapidity is also high, which allows you to play more fireballs. As for burning, the only explosive high-damage skill of Fire Method has the effect of collecting all the point damage you have released to your current target (even if you have jumped half, he will correctly calculate the complete point damage, not half) and release it into a new point (this is new, actually doubling the point damage to your current target). So when you release, the higher the point damage on the target, the better. This is related to the damage you point (the number of consecutive crits that are superimposed and refreshed, and the point where the live bomb is exploded. Try to have a live ammunition on the target, which will ignite after your critical strike, causing an inflammatory explosion. Throw it on the spot with an inflammatory explosion and release it. It is best to trigger the explosion by two consecutive fireball crits, which can achieve almost perfect combustion use. In addition, when you appear on the BOSS, there is a delay of about 1S from burning to burning, so try not to put it when the ignition time is less than1s.
