Karaul's Clutches spawn in once upon entering The Brumal Aerie, and can also be summoned by Lua error in Module:VarQuery at line 21: No results found...
The eggs themselves do nothing at all, staying in the nests. They can be destroyed, which prevents them from hatching later. The eggs do not hatch unless Karaul Silverwing forces them to. She does this by launching a projectile towards random eggs upon landing. The projectiles travel at a speed of 1000. The eggs hatch 1.5 seconds after the projectiles reach them. Each egg hatches 3 Silverwing Clutchling, which then attack the players.
