Enchant

Enchants equipped weapon of targeted character or minion adds fire damage to all weapons.

Enchant is a Sorceress Fire skill (level 18, requires Warmth and Fire Ball) and the prerequisite of Hydra. It is a buff: cast on yourself, a party member, a mercenary or a pet, it adds fire damage and +% attack rating to their attacks for minutes at a time. The numbers that decide it are 68–89 fire damage and +191% attack rating at level 20, for 10 minutes.

The numbers

The fire damage comes from the EMin/EMax columns, halved by HitShift 7. The minimum starts at 8 and grows +1.5 a level to level 8, +3.5 to 16, +5.5 to 22, +7.5 to 28 and +9.5 a level past that; the maximum starts at 10 and grows +2.5, +4.5, +6.5, +8.5 and +10.5 in the same brackets. That is 68–89 at level 20 and 143–174 at level 30.

The attack rating bonus is ToHit 20 plus LevToHit 9 a level: +191% at level 20. Duration is ln12 frames, Param1 3,600 plus Param2 600 a level, so 144 seconds at level 1 and 24 seconds more a level: 600 seconds at level 20. All three lines read lvl, so +skills count, and the row is flagged InTown: it can be cast in town.

Mana is 25 at level 1 and 1 more a level (manashift 8): 44 at level 20.

How it works

Enchant puts the state "enchant" on the target for the duration and that state carries three stats straight from the row: firemindam and firemaxdam (the damage line) and item_tohit_percent (the attack rating line). The fire damage is added to the target's attacks like fire damage on a weapon, so it goes through the attack's Chance to Hit roll and the defender's fire resistance, see Dealing Elemental Damage; the attack rating line is a percentage bonus like Bonus to Attack Rating on an item.

The Basin's page sets out who it reaches: the caster and selected allied players, mercenaries and pets, but not converted monsters or Reanimated ones. A higher level overwrites a lower one, not the reverse, and recasting the same level resets the duration. The skill level is read when it is cast, and so is the caster's +% fire skill damage: the Basin's page says Fire Mastery and items' +% Fire Skill Damage are applied when Enchant is cast, then applied again at the moment of a melee attack, so a melee hit's Enchant damage is multiplied twice; it says D2R applies the second multiplication to ranged attacks as well. The fire damage is also added to the arrows and explosions of Exploding Arrow and Immolation Arrow.

Param3 (33, the table's "% Damage for Ranged Weapons") is still in the row, but the Basin's page says the fire damage was never cut to a third on a ranged attack and that D2R's description was corrected to drop the claim.

Synergies and +skills

• Warmth: +9% fire damage per level (skills.txt Param8 = 9; the calc reads skill('Warmth'.blvl), hard points only).
• Enchant feeds nothing.
• Fire Mastery multiplies the fire damage, at cast and again on a melee hit, as above.

Against players

Enchant is a buff and never touches another player itself. The attacks it adds damage to are player hits like any other, cut to 17% of their value by the player-versus-player rule, see Player versus Player.

Build notes

• The damage line is small on its own (68–89 at level 20); the hard points in Warmth and the double Fire Mastery multiplication on melee are what make it a build.
• The duration, 10 minutes at level 20, and the InTown flag mean a Sorceress can buff a whole party at the start of a run and not again.
• The +191% attack rating at level 20 is the quiet half of the skill: it is as much as a large Attack Rating item for anyone it is cast on.
