Pillars of Eternity killing Alpine dragon, PotD difficulty

Video showing the kill of the Alpine dragon in white marsh. PotD difficulty. No durgan steel enchantments, 13\14 all custom party (Paladin tank, chanter tank, priest, ranger, cipher, wizard). Some mistakes where made though (like aspd potion on ranger and cipher wasnt activated - canceled it with the next potion accidentally, didnt resed the bear with pally, some supressed items\buffs etc... ). The idea of the party is 200% aspd on ranger and cipher with chanter song, pally buff, time thief of ranger, aspd pots, items with aspd buffs (gloves, godag bow etc). Wizard and priest for support\control\aoe damage.
