Poison Damage adds Damage over Time, so it does not add high Damage values, but applies utility.There are a lot of Cold Resistance / Immunity monsters.Cold Damage adds the lowest Damage values, but applies powerful Crowd Control affects via Cold Length.Lightning Damage adds the highest Maximum Damage values, with the easiest to break Lightning Resistance / Immunity.Fire Damage is arguably the 'weakest' since the most monsters in the game have Fire Resistance / Immunity.

Magic Damage is arguably the 'strongest' since so few monsters have Magic Resistance / Immunity.Vengeance damage is further increased by +xx% Skill Damage, whereas Non-Physical Damage from items, does not.This includes Vengeance Elemental Damage from earlier in the calculation.The Physical Damage conversion occurs later in this calculation, but the added Fire Damage from the skill is applied here.Any Skill which adds Non-Physical Damage to their attack is included at this point of the calculation.vengeance calculates its bonus Elemental Damage at this point.Boots and Shields do not benefit from +xx Min and Max Damage.In LOD, The Cranium Basher shows +20 Minimum Damage, but the D2Planner shows this properly as Adds 20 Damage.The Weapon Damage values, and Character Screen shows the correct bonus to both Min and Max. On Two-Handed Weapons (excluding Swords), if the +xx Min = +xx Max, the item displays the stat as ONLY +xx Minimum Damage.44 Min to 34 Max Damage is = 34 Min to 44 Max for the purposes of determining the Damage value per attack.The D2Planner shows the correct item's stats: Hurlbat of Transcendence.The in-game item stat range shows the Min = Max, which is incorrect. This is not properly calculated on the Character Screen.

If +xx Minimum Damage would cause the Min Dmg > Max Dmg on a ranged Weapon, the Max Dmg is unchanged.

If +xx Minimum Damage would cause the Min Dmg > Max Dmg on a melee Weapon, the Max Dmg becomes Min Dmg + 1.

If an item would add more Min Damage than Max, the two stats are displayed separately.

When an item would add Minimum AND Maximum Damage, the item displays this stat as Adds xx to xx Damage.

+xx Min / Max on other items does not reflect on the equipped Weapon.

When the +xx Min / Max Damage is On Weapon, the stats displayed on the Weapon itself reflects this bonus.
