Edition covered

The 2002 Wailing Death campaign and its third-edition D&D rules. Images show Neverwinter Nights: Enhanced Edition and may depict bundled adventures. Shadows of Undrentide, Hordes of the Underdark and community modules have different companions and campaign rules.

Higher AC and attack bonus are better

Enhanced Edition party battles large enemies inside a decorated chamber.

Neverwinter Nights uses ascending armor class and attack bonuses, unlike Baldur's Gate's descending THAC0 system. Compare the final character-sheet values after equipment and ability adjustments.

Important values
Value	Preferred direction	Use
Armor class	Higher	Makes attacks against you harder
Attack bonus	Higher	Improves weapon hit chances
Saving throw	Higher bonus	Helps resist matching effects
Hit points	Higher	Lets the character absorb more damage

Recognize threatened actions

Moving away, using ranged attacks or casting near a threatening opponent can expose a character to attacks of opportunity. Use appropriate skills, modes or positioning rather than assuming every menu action is safe.

Close-range risks
Action	Risk	Useful response
Cast while threatened	Interruption or opportunity attack	Create space or use appropriate casting options
Use a bow in melee	Enemy threatens the archer	Switch weapon or reposition
Leave an enemy's reach	Opportunity attack	Consider defensive movement options
Wear heavy armor as an arcane caster	Spell failure and movement tradeoffs	Inspect armor and class rules

Armor has tradeoffs

Heavy armor limits the Dexterity contribution it can use and can interfere with arcane spellcasting. An item with a larger base armor value is not automatically the best choice for every build.

Read the combat feedback

Damage resistance, concealment, spell defenses and attack rolls are different layers. If an attack repeatedly fails, inspect the log before replacing your entire weapon plan.

Useful tip

Damage resistance, concealment, spell defenses and attack rolls are different layers. If an attack repeatedly fails, inspect the log before replacing your entire weapon plan.
