Adventure in Dan-thurás

Tinker?

• Mending & Repair: Patching mundane utilities like torn clothes, pots, and broken household wares. 
• Improvised Gear: Creating simple, lightweight items from the standard equipment list, such as caltrops, pulleys, signal whistles, or a tinderbox. 
• Clockwork Gadgets: Small mechanical devices like wind-up timers, intricate trap triggers, and tiny music boxes. 
• Improvised Weapons/Explosives: Modifying ammunition, crafting traps, or assembling alchemical grenade triggers (often with DM approval). 

Wood stone  or bone would also work…

"But I would need tinker's tools, as I do not have any right now." Yenn looks down sheepishly.

“Joe Joe Joe.  What are the chances you’ve got tinker tools?”  Orien says while holding out his jug of wine.
