Diablo and Hellfire Difficulty

Singleplayer Diablo only has normal difficulty, there is a workaround but you will first have to play through the game in multiplayer up to level 30 (for Hell), Google it for more info. Multiplayer Diablo has 3 difficulties named the same as those in Hellfire. Hellfire is singleplayer only (there is a way of playing multiplayer, Google it, I don't have data for that) and has three difficulties named Normal, Nightmare and Hell. Singleplayer Hellfire Nightmare and Hell difficulties are harder than singleplayer Diablo on those difficulties, details below. As difficulties increase the player will need a higher to hit chance, more than what is described by the game as 100%, it is worth saying that no matter what your to hit chance is any monster on any level will always have at least a 5 percent chance of avoiding your attack so 100% or more does not give a guaranteed hit.

Note that the formula to calculate the increased monster to hit chance varies depending upon whether the attack is melee, ranged physical or spell based. For example the chance for a monster hitting you with a spell increases by more than the chance that a monster will hit you with melee. Data relating to the Diablo base game is calculated using what is known to be true in multiplayer, monster hitpoints are about half in singleplayer of what they are in multiplayer.

A note about monster level. Sometimes damage dealt by either a monster or the player changes depending upon the monster's or player's level. A spell which does 20 damage when dealt by a level 8 monster will be a lot more when cast by a level 20 monster. Monster levels increase with difficulty.

**Normal Diablo**. What you see is what you get. Some monsters are resistant or immune to fire, lightning or magic damage. Diablo is not resistant to Holy Bolt.

**Normal Hellfire**. The same as the base game but Diablo is resistant (not immune) to Holy Bolt.

Example: Rotting Carcass (Diablo and Hellfire). Monster level 4. Hitpoints 12. Armour Class 15. To hit player 25%. Damage 5 to 15. Immune to magic.

**Nightmare Diablo**. Monsters have more hitpoints, more armour, have an increased chance of hitting you and do more damage.

**Nightmare Hellfire**. As above but hitpoints have been increased by an additional 50 points.

Example: Rotting Carcass (Diablo). Monster level 19. Hitpoints 36. Armour Class 65. To hit player 110%. Damage 14 to 34. Immune to magic.

Example: Rotting Carcass (Hellfire). Monster level 19. Hitpoints 86. Armour Class 65. To hit player 110%. Damage 14 to 34. Immune to magic.

**Hell Diablo**. Monsters have more hitpoints, more armour, have an increased chance of hitting you and do more damage. Added immunities and resistances.

**Hell Hellfire**. As above but hitpoints have been increased by an additional 100 points.

Example: Rotting Carcass (Diablo). Monster level 34. Hitpoints 48. Armour Class 95. To hit player 145%. Damage 14 to 34. Immune to magic. Resistant to Fire.

Example: Rotting Carcass (Hellfire). Monster level 34. Hitpoints 148. Armour Class 95. To hit player 145%. Damage 14 to 34. Immune to magic. Resistant to Fire.
