Candle of the Surreptitious Scholar
When you speak the command word and use an action to expend 1 charge, the candle’s flame to spring to life. Its bluish flame provides clear illumination within 5 feet and _dim light_ for another 5 feet. The enchantment of the candle is such that the light that it sheds is visible only to you, allowing you to read, write, or engage in other tasks with no penalties from darkness. Each charge is good for 1 hour of illumination, after which the candle winks out.
By expending all 3 charges at once, you can create an effect identical to _light_ except that only you are able to see the light it sheds.
If you expend the last charge, roll a d20\. On a result of 5 or less, the candle loses its magic and becomes a mundane item.
