- 500-999 gp: Rolls 1 extra die on all effects, DC is increased by 1
- 1000-2499 gp: Rolls 2 extra dice on all effects, DC is increased by 2
- 2500-4999 gp: Rolls 3 extra dice on all effects, DC is increased by 3

Engraved Infusions. You can spend 8 hours to enchant and carve a magical engraving into gemstone that is worth at least 100 gp, at the end of the process you must also succeed on a Dexterity (Jeweller’s Tools) or Intelligence (Jeweller’s Tools) check.
On a failed check, the gemstone’s value is decreased by 10% for each point of difference between the roll and the DC, destroying the gem if you fail by 10 or more.
The DC of the roll depends on the chosen engraving, and it increases the value of the gem by a specified amount:
- Explosive (DC 7 – 50 gp). The gem can be used as an improvised ranged weapon or as ammunition into a sling. On a hit, the target takes extra 2d10 damage and all creatures within 10 feet of them must make a DC 13 Dexterity saving throw, taking 2d10 damage of the gemstone’s type on a failure or half as much on a success.
- On a hit, the gemstone has a 25% chance of being destroyed.
- Protective (DC 10 – 150 gp). If a creature takes damage corresponding to the gemstone’s damage type, they can use their reaction to reduce the damage by 1d10.
- When used, the gemstone has a 10% chance of losing its magical properties.
- The gemstone must be held in at least one hand or embedded into a weapon or shield.
- Offensive (DC 10 – 150 gp). If embedded into a weapon as an action, it deals extra 1d4 damage of the gemstone’s type for 1 minute. The gemstone loses its magical powers once the duration expires.
- Potent (DC 13 – 250 gp). When you force a creature to make a saving throw with your spells or class abilities, you can use your reaction to increase the DC by 1 (You must use this reaction before the target rolls).
- When used, the gemstone has a 25% chance of losing its magical properties.
- The gemstone must be held in at least one hand or embedded into a weapon, shield or a spellcasting focus.
- If you embed this gemstone into a magical item, it can also be used to increase the DC of its abilities.

- 2500-4999 gp: 7 days
