-- Surprise Round Begins --
Matriarch attacks Diadell twice using her Action. She already used a Bonus Action for the surprise round to phase in next to Diadell. She rolls a 14 and a 9. She gets a +6 for attack, more than her mates get. So a total of 20 and 15. Diadell has an AC of 16. So she hit once. She does 1d10+4 damage. She rolls a 9+4=13. Diadell makes her Constitution save throw by rolling a 19. She takes half damage for the poison. Spider Queen rolls 4d8 and gets a 12. That's 6 HP off for poison damage. So she loses 25 HP in one round. She has 2 HP left.
Phase Spider 1 attacks Lynari. It rolls a 7 to hit and only gets a +4. That's 11. Barely misses Lynari with her AC of 12. It also used its bonus action to phase next to them, so it is done for the round.
Phase Spider 2 attacks Vel. It rolls an 18+2=20. Vel's AC is 12. He is hit for 1d10+2 damage. It rolls a 4, so 6 damage. He rolls a 10 for his Constitution Save. He gets a +1, so he rolled a total of 11, and that's all he needed. He succeeds and takes half damage from the poison. The spider's poison is 4d8 and it rolls a 15. That's 21 HP off Vel in one round. He had 30 HP to begin with. He now only has 9 HP left.
-- End of Surprise Round --
Already, 2 of the party are almost dead, and that is just the surprise round. Will they succeed?
Seems like a pretty tough boss fight already, and we've hardly even started.
