Your party is fine - it should give you plenty of options.
HoW *does* have improved AI - the monsters have a "call to arms" function that draws nearer monsters into combat. You cannot sneak around and draw them off one at a time. This is why preparation is important - prepare a defense and draw the monsters onto it.
Two notes - you are using a lot of 2-handed weapons. This means you are not using some of the excellent +2, +3 and +4 shields avaialable to lower your AC. You are also lacking a mage - this, whilst being a personal choice, might affect your ability to cause damage later in the game.
But other than that, your party sounds great. All of your characters can wear heavy armour. You have 3 characters capable of casting defensive spells (figher/druid, fighter/cleric and cleric) - use this. Spells like curse will make it difficult for the undead to hit you, prayer will make it easier to hit them, defensive harmony reduces your AC. Do you use "turn undead"? It won't damage the wights but it will turn them to give you better odds.  |
