If I recall correctly a multiple Dragon Fight was request from the players after the Dragon fights in Baldur’s Gate II, so Bioware granted this request and offered such fight. So here we are again facing two Dragons at the same time, a Corrupted Copper Dragon and a Corrupted Silver Dragon. And to add to the problem the Dragons will immediately attack as soon as you teleport here and leave no time for preparation. However this time your character is also more powerful than he/she was when you faced the Dragons at Moonwood and the Dragons are not as powerful as the ancient ones. You can prepare for this fight though before you enter the portal from the Source Stone Sanctuary. Use any means possibly to raise your stats and check rolls and hotkey the Heal potions and the Stone of Recall. Once again this is a place that Barkskins and Stoneskins can be very useful. It would be too difficult to place any traps since the Dragons attack you on sight and even if you are skilled in hiding Dragon also have True Sight. Once the fight begins concentrate your attack on the Copper one since he is weaker and easier to hit than the silver Dragon. With little luck you can defeat the Copper Dragon pretty quick and then go for the Silver Dragon. The silver Dragon is more powerful and you will be having a hard time if you engage him in melee. Keep an eye on your hit points and act accordantly and watch out for the breath attacks of the Dragon, some of then can paralyze you so immunity to paralyze will prove most useful. Finally when both Dragons are dead retrieve the Guardian Keys from each of the bodies and proceed to area #3. The keys are needed to unlock the two gates that block the way to the Inner Sanctum
If you thought fighting one dragon at a time was tough, well here's two. They do the
normal amount of dragon damage, as well as knockdowns, with thier own immunities. This is
a very tough battle and keep your attacks focused on one at a time, use the recall stone
and you'll be able to get past them.
Get ready for a terrible fight. This battle ranges from Quite Easy (if
you have the Belt of Greater Swordsmanship) to Nearly Impossible (if
you don't.) It features a Copper and a Silver dragon, corrupted from
their milennia hanging in the source stone with Morag and her crew.
Like the Genie said, "TEN THOUSAND YEARS...will give you such a crik in
the neck!" The dragons can obviously sympathize, so make sure you have
Stoneskin, Cat's Grace, Bull's Strength (especially), Endurance,
Elemental Resistance or whichever of those apply to you. Don't bother
Hiding- they can see you as soon as you come in, and have True Seeing
on them at any rate. You might try immediately running back and to your
left, pinning yourself in the corner of the wall and lake- sometimes
you'll be able to hedge out one of the dragons. Concentrate on the
Copper first- both Dragons will do about the same damage, but the
Copper is much easier to kill. The undertaking of killing two Dragons
is not as incredible as you might think- these are far from Ancient Red
Wyrms. Linu, of course, is the best girl for the job- Dragons are much
easier when reduced to 1d4+1 hitpoints and Daelan's knockdown isn't
going to work on the Dragons. Don't be stingy with the Heal potions,
spells, or commands. After the Dragons are dead, save the game to a
separate file...for the last time.
