As it was too good to be used among the group, it went on to share the toothpick with dragons, demons and such in Volcano, Dragon Mountain, Demon Web and Ravenloft. Needless to say, the mobs didn't argue as they silently turned into corpses, resulting in from a sneaky placement of toothpick in their backs.
The group was led by yours truly, backed up by a triple poker Dedsune, a valiant tank Caldrick, a generous healer and raiser Draco, as well as other supporters, such as Osric, Gargon, Nightwolf and others. The gang was also complimented by a couple of newcomers, who (probably) were too astounded by the experience to coherently share their emotions.
While the group didn't pop much, it sure did leave a trail of corpses and had a lot of fun (triple toothpick stab on Tiamat to awful for one), etc.
Did I thank Blaster yet? Thanks, Blaster!

Hopefully, there will be more such exciting opportunities, not only limited to grenades, but also including temporary pass to Lyme to off-lymers (with specs), etc.
Thanks everyone for participating (Blaster, too!).
