Drider is 30ft away (the far side of the room). For the init, after getting half the party I had rolled the rest and the Drider had still won so the Gloombind bolts were Round 1 (its like -Ve energy scorching ray so no Saving throws)
She sounds fine
Its 30ft away, round 1, so feel free to charge in (joining Kona) and start slapping it around (post the gloomblind bolts)
