Dragon tactics: (there are several)
- lower magic resistance / harm / magic-missiles
Try to cast about 3 lower-resistances, hit him with a "harm"-spell, now he only has 1 hp left so you magic-missile his a** to some very far away place
- Lower Magic Resistance / greater-malison, doom, spook / finger of death or so
Here you have to get his saving throws down after you lowered his magic resistance, which 'll allow you to polymorph him, slow him, weaken him, kill him with finger of death and so on ... this tactic takes a little longer but is more fun ( Fiirkaag the slow-moving squirl with 3 strenght)
In general you cant tackle a dragon without a mage of some sort, since a dragons "wing-buffet" (you get thrown back and knocked unconscious) plus its low AC and high THACO/Damage, makes it very hard for a group of fighters to get to him.
Further on you should allways summon some cannonfodder, IN GROUPS !!! , not all at the same time, so he waists spells at them.
VERY IMPORTANT TOO !!! :::: let your fighters/ summoned creatures stand AROUND him in a circle !! this means that he cant knock back evry one in a single "wing-buffet". You have to keep him busy in ONE place at all times, do NOT let him walk around, because your mage(s) wont be able to withstand ANY beating by a dragon.
So, basically, you can start attacking dragons when your party reaches a level so high, that it has Lower magic resistance (lvl 12/13 or something)
do keep in mind that lvl 12/13 will be VERY tough if you dont use cheesy tactics
Have fun !!
