So I returned to PoE after a long break and I am playing on POTD. The Adra Dragon fight took days and many hours to work out but I thought I would share the way I finally beat the encounter.
I completed the first conversation with the Adra Dragon and got the Scale Breaker skill, but actually forgot to use it on my successful attempt.
My main character is a Paladin Tank, the rest of the party consist of Eder, Kana, Aloth and Grieving Mother. Plenty of gunnery skills and Arquebuses, Pistols with Beast slaying enchants etc etc. I've just managed to get them to level 13 and apart from the extra level benefits of extra HP etc there is one spell that makes a massive difference - Litany Against Major Afflictions.
Step 1. When we return to the cave post the Dragonslayer meeting nearly all of the party are tucked into the top left hand corner.
Step 2. The Paladin and Durance are close together at the bottom of the steps into the main cave. When MT engages the Dragon he gets the LaMA buff (this allows him to avoid getting stunned/paralyzed/zapped) and he runs clockwise around to the top right of the cave beyond the Adragans and tucks in to be as protected as possible by the cave wall. He drops some summons and then tries to last as long as possible (Cautious Attack, Zealous Endurance, potions etc etc) and get the Dragon to kill as many Adragan and Blights as possible. It's only a matter of time until he dies.
Step 3. The Xaurips attack the party on the top LH corner and we deal with them as cleanly as possible. The Dragon and any surviving Adragans do NOT approach that LH area and stay near my fallen Paladin so you have some breathing space.
Step 4. I then move my party down to the tunnel at the south of the cave (clearing any remaining Xaurips) and use Kana's summoned Ogres to lure the remaining mobs towards us and let either a. the Dragon kill them b. the Ogres wear them down with repeated attacks or they come into range of the party. Rinse and repeat until it's only the Dragon left.
Step 5. With the Dragon in the centre of the room it's careful positioning of your tanks and the Ogres to keep the Dragon away from ranged characters. Plentiful use of Paralysing scrolls (with a modest success rate) and all the buffs you can maintain to improve accuracy and remove fear. All of those necessities are detailed on this post by lots of people.
It's a satisfying victory and three superb items was a decent reward. Good luck and I hope this help.
