# The Writhing Jar [[The Writhing Jar]] is a unique [[Hallowed Hybrid Flask]]. ## Mechanics Writhing Worms spawned by the The Writhing Jar do not generate flask charges or souls for Vaal skills or [[Soul Eater]]. The jar allows players to gain on-hit effects outside of combat or any time. On-kill effects work for summoning spiders from [[Arakaali's Fang]]. Killing the worms also triggers the on-kill effect of [[The Gull]].
