Skill functions and interactions

• Stages: Flameblast deals more damage at each stage, starting from the second. This means it does base damage at the 1st stage, then 100% plus 165% with hits at the second stage, and so on, resulting in 1485% more Spell Damage modifier at the last stage, or 15.85x base damage with hits, and 540% more damage with ailments at the last stage, or 6.4x ailment damage.

• Cast speed: At base cast speed it takes 2 seconds to reach the maximum stage. Increasing the cast speed reduces the time to reach the next stage, similar to how IncinerateIncinerateSpell, Fire, Channelling, AoE

Unlike other skills, which are used once and quickly finish, when you use a channelled skill, it doesn't finish until you release the relevant button/key. You continue performing the same skill. You need to pay mana repeatedly to keep the skill going. The channelled skill's mana cost must be paid again to maintain it with a frequency determined by the cast time. If you can't pay, the skill will end, just as if you'd lifted the button. Dying, being stunned, and other game mechanics that interrupt the use of skills will cause channelling to end as well. Effects which trigger when you use a skill will only trigger when you initially start channelling - regardless of how long you maintain a channelled skill, it's still the same use of the skill. You need to stop channelling if you want to use it again.
2.1.0	Damage has been increased by around 20% at all levels.
2.0.0	Now grants 1% increased damage per 1% quality (quality no longer affects ignite chance). No longer works with Spell Echo. Base Cast Speed has been increased from a cast time of 300ms to 200ms to compensate for no longer working with Spell Echo.
1.3.1b	Reduced the damage of Flameblast by 20%.
1.2.0	We have reduced the critical strike chance from 6% to 5%. We have reduced the damage by 15% at all levels.
1.1.1	Fixed a problem where Flameblast was accidentally buffed heavily in 1.1.0. Based on feedback on the insane version, we then buffed the pre-1.1.0 version by 48% on purpose in this patch.
1.0.4	Flameblast has been added to the game.
