Item Supercharger

By means of this spell, a chronomancer attempts to alter the salient abilities of a magical item. This attempt can be made only once per item, and has a significant chance of ruining the item forever. Use the table to figure the chance for success.

Table 22: Item Supercharging Success Chances Item | Frequency | Duration -------+-----------+--------- Potion | — | 25% Ring | 60% | 65% Rod | 60% | 80% Staff | 90% | 65% Wand | 85% | 90%

Frequency is the number of times per day the item can be used, or the recharge time required between uses. When this ability is changed, uses per day are doubled or the recharge time halved. For example, the recharge time of a ring of blinking goes from six turns to three.

Duration is how long the effect operates. Altering this doubles the duration. For example, wings of flying could be used for 16 turns at speed 12, instead of eight turns.

The material component is an ounce of mercury.

Notes: Restricted to chronomancers; common.
