Miasma Bolt

Fires a bolt of darkness that releases a cloud of entropy.

Miasma Bolt is the Warlock's first Chaos skill (Chaos Skills, level 1, no prerequisite, unlocks Miasma Chain). It fires the miasmabolt missile, which deals magic damage on impact and releases the miasmaboltcloud missile, a lingering cloud. The numbers that decide it are the bolt, 22–25 magic damage at level 20, and the mana, 11.5 at the same level.

The numbers

• Mana is 2 at level 1 and rises 0.5 a level (mana 4, lvlmana 1, manashift 7) to 11.5 at level 20.
• Magic damage comes from EMin 2 / EMax 4 and their brackets, halved by the row's HitShift 7 (the damage columns are in 128ths rather than 256ths): the minimum grows +1 a level to level 8, +1 to 16, +1.5 to 22, +1.5 to 28, +2 past that; the maximum +1, +1, +2, +2, +3 over the same brackets. Level 1 is 1–2, level 10 is 10–11, level 20 is 22–25, level 30 is 38–47.
• The cloud has three tooltip lines that this page cannot compute, because they read the miasmaboltcloud row of missiles.txt rather than this skill's row: its average magic damage per second, its duration and its radius. The duration line is the cloud's own length plus Enhanced Entropy's level times a cloud parameter, capped at 100 frames (4 seconds); Enhanced Entropy's own tooltip prints that bonus as 0.2 seconds a level, 4 seconds at level 20, and prints the Miasma radius as 2 yards at Enhanced Entropy level 1, 3 from level 5 and 4 from level 10.

The damage line reads lvl, so +skills from items count; the synergy terms read blvl.

How it works

The bolt is a missile: it flies until it hits, and the hit is magic damage (EType mag), which goes through the target's magic resistance and nothing else, see Dealing Elemental Damage. The row has no ToHit, no SrcDam and no attack rating, so the bolt always hits what it touches and carries none of your weapon's damage or modifiers. Where it lands it releases the cloud named in the game's description, the entropy that Enhanced Entropy widens and lengthens. The row names no aura, state or periodic column: everything after the hit belongs to the cloud missile.

The bolt itself is 22–25 at level 20; the synergies and the cloud are where the skill's damage is, and the cloud's figures are not in this page's table.

Synergies and +skills

Two synergies, each with two lines: Miasma Chain and Abyss add +10% magic damage per hard point to the bolt (Param8, EDmgSymPerCalc) and +20% average magic damage per second per hard point to the cloud (Param9). Both read blvl. Miasma Bolt in turn gives +10% magic damage and +20% average magic damage per second per hard point to Miasma Chain, and +10% of each to Abyss (that row's Param8). Enhanced Entropy is the passive that lengthens and widens the cloud; it is not a synergy line on this row.

Against players

A player's hit on another player is cut to 17% of its value (difficultylevels.txt PlayerDamagePercentVSPlayer) before anything else, see Player versus Player; the bolt's magic damage is cut the same way. The table has no separate player value for the cloud.

Build notes

• The row's own growth is 3 and 4 a level at level 20; each hard point in Miasma Chain or Abyss is +10% to the bolt and +20% per second to the cloud.
• Mana is 11.5 at level 20 and 0.5 a level, cheap for a bolt plus a cloud.
• Levels past 20 come from +skills and keep adding: level 30 is 38–47.
