Armageddon

Create a meteor shower to rain fiery destruction on nearby enemies.

Armageddon is the Druid's level 30 Elemental skill, requiring Volcano; it unlocks nothing. It is a buff on the caster (aurastate armageddon): for 10 seconds rocks fall at random around wherever you are, each dealing fire plus physical damage where it lands. It is the one fire skill the Basin says can be cast as a werewolf or werebear. The numbers that decide it are the per-rock damage, 390–471 fire plus 244–271 physical at level 20, the duration, 10 seconds plus 2 per hard point in Fissure, and the cost, a flat 35 mana with no casting delay.

The numbers

• Fire damage is the EMin/EMax columns: 25–75 at level 1, then +15/+16 a level to level 8, +20/+22 to 16, +25/+27 to 22, +31/+34 to 28 and +38/+40 past that (EMinLev1–5 and EMaxLev1–5). 170–231 at level 10, 390–471 at level 20, 702–809 at level 30.
• Physical damage is the MinDam/MaxDam columns: 18–26 at level 1, then +10/+11 a level to level 8, +12/+13 to 16, +15/+16 to 22, +18/+19 to 28 and +22/+23 past that. 112–129 at level 10, 244–271 at level 20, 426–463 at level 30. The Basin's page warns that the older tooltip did not display the physical damage; the current skilldesc row has a line for it.
• Fire damage per second from the lingering fire is a tooltip line that reads the missile table and is not in the repo's bank, so it is not in the table above. The Basin's page gives the display formula, 3 fires × bit rate × 25 ÷ 256, and warns that only one fire lingers after each impact and that +% fire skill damage does not apply to it although the display is computed as if it did.
• Radius is Param3 = 8 (aurarangecalc par3), which the tooltip prints as par3 × 2 ÷ 3 = 5⅓ yards at every level, so it is not in the table.
• Duration is auralencalc = ln12 + Fissure hard points × Param7: Param1 250 frames ("Duration baseline"), Param2 0 a level, so 10 seconds at every level, plus Param7 50 frames, 2 seconds per hard point in Fissure (the table calls it "Eruption"). It is constant without the synergy, so it is not in the table.
• Rocks are created every Param4 = 6 frames ("Delay between Missiles created").
• Mana is a flat 35, and the row has no delay column; the Basin records the older game's 6-second global delay and none in D2R.

The damage lines read lvl, so +skills from items raise them; all four synergies read hard points only.

How it works

Armageddon is a cast on your cast rate (Casting Speed). The Basin's description: rocks rain down at random inside an 11⅓-yard square centred on the caster's current position when each rock is created, so the shower follows you; on impact, physical and fire damage are applied within a 2-yard radius and a fire lingers briefly, applying fire damage. Casting again while it runs simply resets the duration. The damage cannot be blocked. The fire goes through Dealing Elemental Damage, cut by Fire Resist and raised by Fire Skill Damage; the physical through Dealing Physical Damage.

The shower is random and stays close to the caster, so it is not an aimed attack: the Basin's judgement is that its best use is as area damage around a Fire Claws werewolf or werebear, since the two skills share their synergies.

Synergies and +skills

Four synergies. Fissure, +2 seconds duration per level (Param7 = 50 frames, "Duration synergy", inside the duration calc). Firestorm and Molten Boulder, +14% fire damage per level each (Param8, "Fire Damage synergy", through EDmgSymPerCalc = (skill('Molten Boulder'.blvl) + skill('Firestorm'.blvl)) × par8). Volcano, +18% damage per level on the physical (Param6, "Physical Damage synergy", through DmgSymPerCalc = skill('Volcano'.blvl) × par6). All read hard points only. The Basin's page lists Volcano as a fire synergy in the older game; the current row puts it on the physical half. Armageddon's own hard points are a synergy for Volcano (+12% fire a point). The Basin also lists Hurricane as a prerequisite in the older game; the current row requires only Volcano.

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 Basin's page says nothing more about Armageddon against players.

Build notes

• Twenty hard points in Fissure turn 10 seconds into 50, and with no delay the shower never has to be down; the other three synergies are +560% on the fire and +360% on the physical.
• The physical half rides through fire immunes and is nearly two thirds of the fire at level 20.
• Castable as a wolf or bear and centred on you: a Fire Claws shapeshifter gets area damage from the same synergy points, for 35 mana a cast.
