Fire Magic Skill Tree

Focus your mind and launch a flaming projectile that deals magic damage equal to 400% of Magic Attack Power to all units within range and applies 5 Burning for 10 seconds.

This attack can also damage allies.

Effects & keywords

  • Burning (on enemy): 3 magic damage per stack, every 1 second (flat, does not scale with attack power; stacks up to 50). Example: 10 stacks = 30 magic damage/second before resistance. Duration is set by the applying skill. It never misses, is never guarded or critical and goes past Barrier, but the target's Magic Resistance still cuts it (x 100 / (100 + resistance)). On a Wet or Heavily Wet target each tick is x0.8.

Damage

Shown for stock Liana, Fire Wooden Staff at level 5 (level cap). Pick your physical and magic units in the sidebar.
Expected per cast 384 magic per target
= MAtk 89.3 x 400% x 1.076 crit
Versus benchmark 71.2% of Acid Slogel HP
Damage per energy 54.9 per energy at 1 target, 164.7 at 3 targets (7 energy)
Damage per second 13.7 per second at 1 target, 41.2 at 3 targets (from the 30 s cooldown)
Area 13 cells (Manhattan radius 2): up to 13 targets, 4,997 total if every cell is hit. Also hits allies in the area
Per cast range 384 direct only, up to 534 per hit target with the full 150 burn damage from one application.
Damage over time Applies 5 Burning = 15 damage/second (3/stack/s x 5 stacks) for 10 s = 150 total per application, before resistance. It is flat (attack power does not change it). It never misses, is never guarded or critical and goes past Barrier, but the target's Magic Resistance still cuts it (x 100 / (100 + resistance)). On a Wet or Heavily Wet target each tick is x0.8. Re-applied on each hit: at this caster's attack speed (0.6/s) about 32 stacks stay up, for ~96/s sustained.
Versus median 3.1x the median magic active per cast
Burning skips Barrier and never misses, but the target's Magic Resistance still cuts each tick.
Numbers are before target resistance (damage x 100 / (100 + R); most monsters have 0, armored ones up to 60 for a 37.5% cut) and before hit chance, dodge and guard. Combat difficulty does not change your own damage.

How the math works

Each unit in the area takes 400% of Magic Attack Power as Magic damage, then gets 5 Burning for 10s.

When it runs: On cast.

What it applies to: Targets come from the skill's area. SkillTable sets AffectTarget to MultipleAny, so allies in the area are hit too.

Things the tooltip does not tell you

  • The routine never reads the Burning stack count, so the damage does not grow with Burning.
  • Fireproof does not double the Burning it puts on enemies; Fireproof only doubles Burning that lands on its holder.
