Lajav (5e Equipment)
From D&D Wiki
Martial Melee Weapons
The Lajav is a Kreen weapon that looks much like an over size nut cracker, standing about the size of a staff when straightened. This weapon is two pieces of wood, bone, or metal connected by a sturdy but flexible hinge. Each side of the weapon has a griping handle at the ends. Above these grips starts a row teeth used for crushing, usually made of Dasl but other materials have been used. This weapon is often used to grab a hold of enemies then crush them like a nut.
Venom and Crystal
The production of Dasl is a well guarded secret among the kreen and is a very special to them. So special in fact that they almost view it as part of themselves and will not often part with it or weapons made of it. The making of dasl is done by chewing on common sappy plants and mixing their venom with the chewed plant juice, then spiting it onto sand. However this paralysis the kreens venom glands any time they chew it and dose not allow them to use there venomous bite, after a long rest the kreen regain it's use. The dasl mixture stays soft for about a day and can be shaped by the maker till it hardens. Due to dasl's composition it must be made into smaller pieces then bound together with more wet dasl, this still gives a seamless and smooth look but takes time. The time a dasl weapon takes to make is the weapons weight times 5. For example a Lajav weights 5 lb times 5, this weapon will take 25 days to make. Dasl properties dose not allow for it to make longer weapons like swords or wider/thinner structures like armor, if it was ever made like this it would shatter the first time used. Dasl is best used for short thicker blades like wide daggers, gythka heads, axe blades, arrow and spear heads, and morning star spikes. I have changed some things to work better in 5e and general campaigns. If you would like more info I obtained my source material from this book it is 2e so may things are updated but the lore is sound and good. https://dnd.rem.uz/Advanced%20D%26D%20(unsorted)/Accessory%20-%20DS%20-%20Thri-Kreen%20of%20Athas.pdf
