Your flury of attacks does...little (well, 14 m.missile damage).
The gargoyle reverts to semi-stone and launches a now familiar flury of its own. Forge is missed, as is Buckthorn, but Dayereth and Simorai are both hit. It then settles within reach of those two and hits them more (AP, 68 damage on Sim, 104! damage on Dayer). Then, it flies back to its favored pedastal (#1).
No roll 20 access today, but will have it tomorrow. It goes again by about 10:30 AM tuesday.
