World of Aloth
Wondrous Item
Very Rare
This long metal tube has draconic runes written on it. They translate into draconic boom tube. The head of the tube is shaped like a dragon head and it has a beautiful grip shaped like a dragon’s tail.
As an action you can say the trigger word “Mercy” in draconic. When activated the boom tube shoots a big bolt of lightning in a 5 feet wide 90 feet long line. All creatures in the line must make a dexterity saving throw DC 18 or take 10d8 lightning damage on a failed save or half damage on a successful save. Once used the Boom Tube can not be used until it has been fed a vial of storm salt.
After each use of the boom tube, roll a d20. On a 1, the boom tube is partly destroyed and cannot be used. After each shot the chance of partly destroying the boom tube increases by one until it has been given 24 hours to cool down in which case the chance is reduced to 1. To fix a partly destroyed boom tube a creature with proficiency in both arcana and tinkering tools can spend 1000 gold and one day to attempt to fix it. At the end of the day you must succeed on an arcana check and tinkering check 15 plus the chance of destruction when destroyed. If you succeed on both checks the boom tube is fixed, if you succeed on one the boom tube is not fixed and the process must be attempted again with all resources lost, and if you fail both checks the boom tube is completely destroyed and cannot be fixed.
