Inferno

Creates a continuous jet of flame to scorch your enemies.

Inferno is a Sorceress Fire skill (level 6, no prerequisite) and the prerequisite of Blaze. Hold the button and the Sorceress breathes a stream of fire missiles for as long as you keep casting, paying mana continuously instead of per cast. The two numbers that decide it are the fire damage per second, 217–238 at level 20 before synergies, and the range, 15.33 yards at level 20.

The numbers

The damage is stored as bit damage in the EMin/EMax columns, scaled by HitShift 3, and the tooltip turns it into a per-second figure with the calc enms*12/256. The underlying minimum starts at 36 and grows +24 a level to level 8, +30 to 16, +34 to 22, +38 to 28 and +42 past that; the maximum starts at 72 and grows +25, +31, +35, +39 and +43 in the same brackets. In per-second terms that is 13–27 at level 1, 217–238 at level 20 and 360–384 at level 30. The line reads lvl, so +skills count.

The calc counts 12 hits a second. The Basin's page warns that the LoD tooltip assumed a hit every frame (25 a second) while the real rate was a hit every other frame; the current calc's 12 reflects that rate.

Range is ln12/4*2 ÷3 yards: Param1 is 35 (the "Range baseline (Duration of missile)") and Param2 adds 3 a level, so the range grows by 2 yards every 4 levels, from 5.33 yards at level 1 to 15.33 at level 20. calc1, ln12/2, is the missile's duration in frames.

Mana is paid while you channel. The row has mana 24, lvlmana 1 and manashift 2, which resolves to 0.38 at level 1 and 0.67 at level 20; the tooltip multiplies it up to a cost per second (its mana line reads mps). Param3 is the minimum mana to start casting: 4. The Basin's older table prints 7 8/256 mana a second at level 1 and 10 190/256 at level 20.

How it works

Inferno fires a stream of missiles (srvmissile "infernoflame1") that pierce, so one jet damages every target along its path; the Basin's page says they are size 1 and so travel a very narrow line, and recommends aiming at a distant point rather than selecting a target so the line passes through as many enemies as possible. It is fire damage, reduced by the target's fire resistance, see Dealing Elemental Damage and Resistances and Immunities; as a spell it needs no attack rating.

The row is flagged ContinueCastUnselected and ClearSelectedOnHold, the flags of a held-button cast. The Basin's page says Faster Cast Rate does not shorten the start or the end of the cast: a single click is a 15-frame animation, missiles start in the eleventh frame, and after continuous casting there are four frames before the next action.

Since even a single bit of damage in a frame stops a monster's damage regeneration, the Basin's page says a non-immune target's damage regeneration is halved while it is under the jet.

Synergies and +skills

• Warmth: +16% fire damage per level (skills.txt Param8 = 16; the calc reads skill('Warmth'.blvl), hard points only). The Basin's older value is 13% a level.
• Inferno feeds Fire Wall (+1% fire damage a hard point) and Meteor (+3% to the meteor's ground fire a hard point).
• Fire Mastery multiplies the per-second damage as with any fire skill.

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; each tick of the jet is such a hit. The Basin's page gives no other rule for Inferno against players.

Build notes

• The per-second figure assumes the target stays in the jet; the range at level 20, 15.33 yards, is what decides how long it does.
• Warmth is the only synergy and it reads hard points, so 20 points there is worth +320% while +skills on gear only move the base line.
• Keep at least 4 mana spare: the jet will not start below Param3.
