First time, I used a Battlemaster fighter shield dwarf. With Gale, Shadowheart and Astarian. My shield Dwarf and Shadowheart both had medium armour. Astarian +1 Leather I think.
The whole party had aid cast on them before the fight, gale had mage armour and armour of agathys cast on him (level 2 armour of agathys).
IN my second fight I had a party of 4 customs - Shield dwarf mage with headband of intellect and shattered flail, Githyanki strength based rogue with the +1 tyr greatsword, Life cleric and a beastmaster ranger. Aid cast pre-battle. This one since I had a fairly optimised group with decvent magic items was a push over. My rogue didn't even join the fight for the first 2 rounds, instead I had her jump into the storage room and loot it and then jump back.
