The Dryads area healing spells cured poison every second as they healed, so the group members weren't even noticing the damage from the ranged attacks. It was only a small amount per second, but it added up fast, as it stacked if it wasn't cured.

At first, they didn't realize what was happening.
Karl was the healer for the run, even though he hadn't personally cast a single healing spell yet. He cast [Eternal Lightning] on the group, but the Dryads did all the actual healing.

All that they knew was that there was a barrier on them, and there were no negative effects stacking up on them. With that, they could pummel the surprisingly durable flying insects with blade skills until they fell from the sky to be torn apart by Carnage.
