Create Spellstone

The caster uses this spell to focus the Weave and bind fragments of raw magical power into a Spellstone.

Creating a Spellstone requires fitting all the collected gemstones into a special fitting that holds them together into the shape of a single large gemstone. The spell must be cast every day over these stones for 90 days. If even a single day is missed the gems shatter into dust and the process must be started over again.

Once successfully completed the newly created Spellstone glows brightly with swirling magical energy. The Spellstone sheds bright light in a 30-foot radius and dim light for an additional 60 feet. The Spellstone can then be inserted into a completed Arcan Conduit to act as a magical energy source.

If a sentient creature holds a completed Spellstone without any sort of protective gear or tools, they will immediately take 1d10 Force damage, and then be granted 9 levels worth of spell slots at the end of their turn if they are still holding the Spellstone. If they do not have enough expended levels of spell slots to be able to recover this much spell energy they will take another 1d10 Force damage for each level worth of spell slots that they were not able to absorb. If a creature who is not able to cast spells holds a Spellstone they will take the 1d10 Force damage immediately, and then another 9d10 force damage at the end of their turn if they are still holding it. Any sort of glove or tool that prevents direct contact with the creatures skin or hide is sufficient to prevent this effect.

If a Spellstone is not mounted into an Arcane Conduit it will spend its charges firing off bursts of arcane energy at random targets every 3d10 minutes. When the Spellstone fires off a burst of arcane energy it shoots 3 Magic Missiles at random creatures within range. If there are no creatures within range it instead deals 3d4+3 Force damage to whatever container it is sitting in or any objects within 1 foot of it. 

The Spellstone can be destroyed by taking 25 points of Bludgeoning damage from a magic weapon. If destroyed the Spellstone shatters and deals 10d10 Force damage to everyone and everything within 100 feet. 

If the Spellstone is brought inside an Antimagic Field spell, the Antimagic Field spell is ended and the Spellstone becomes inert for 24 hours. An inert Spellstone can be safely shattered.
