Luca stabs the Dragon with his Shortsword Vexing it for next turn, using the Bonus Action Steady Aim to gain advantage at the cost of his movement, then the cunning strike Withdraw which allows him to move half his speed anyway to go behind the pillar. However at the end of his turn Ellidira is banished by the dragon, and then I remember that the banish also does force damage so I deal that.
Loonas dashes at half speed through the water, and uses a tactical shift to heal and get a bit more movement to get to the shore. The Dragon uses Guiding Bolt on Balamur to add a bit more damage.
Man they are unlucky. Ellidira is returned in front of Belamur to be easy pickings. The Dragon Recharges and uses it's fire breath after moving into position. It's a fairly weak Fire Breath that rolled low but they all botched their saves again.
Elidria tries to use Hold Monster on the Dragon, but it makes the save, she then retreats into the smaller room. Using it's LA it Pounces on Luca again and brings him to 0, and his Epic Boon of Recovery's Last Stand ability heals him back to half HP.
Belamur Casts Blade Barrier to Divide the Main area in two. The Dragon fails it's save and uses an LA to half the damage as Belamur follows Elidira inside. The Dragon banishes Luca after that to end the second round.
