Physical Description. A 2-lb reddish brass dragon with ruby eyes, a large red spinel gem on its chest, and garnet claws (4 per limb, 16 total). Value: incalculable.(Artefact)
Abilities. The Dragon is semi-sentient. It has a limited memory, and some powers of perception (including sight, hearing, Listen +20, Sense Motive +20, and Spot +20). It is able to detect deception, such as magical attempts to circumvent the XP cost of unlocking learnstones. It can recognize face and voice pairs (the limit is 32 at any given time). It can recognize 128 variations on 2 key commands, each in 8 different languages (Gnome, Common, Draconic, Elf, Dwarf, Sylvan, and Celestial; the native language of manufacture appears to be Gnome).
Learnstone Attunement. The garnet claws of the Arcane Dragon Assistant Tutor (or simply “Dragon”) are similar to knowstones, and are called learnstones. They may function for any class of spontaneous arcane spellcaster. Each learnstone has the potential of acting like a knowstone for a single spell that the owner (the “Acolyte”) is capable of casting, but does not yet know. The gem must be attuned to the spell by being cast by the Acolyte in the presence of another spellcaster (the “Tutor”) who already knows the desired spell, while the Acolyte is in physical contact with the Dragon. The first time the Acolyte casts the spell herself, she must be in the presence of the Tutor.
Success Improvement. All attempts to use the learnstone must be made while the Acolyte is in physical contact with the Dragon (for example, while holding the Dragon). The beginning failure chance for casting the spell is 90% (aside from other factors such as armor). A failure will expend one of the Acolyte’s daily uses of its corresponding spontaneous caster spell level. At least one casting attempt must be successful in the presence of the Tutor before the Acolyte may attempt the spell on her own. Each time the Acolyte successfully casts the spell, the failure chance decreases by 10%, until reaching 0% failure / 100% success after 10 successful casts. If the spell is attempted in the presence of the Tutor, the Acolyte gains a -10% failure circumstance bonus (but the Acolyte still must complete 10 successful casts before gaining a solo chance of 100% success).
XP Cost. The Dragon requires an experience cost of 250 XP from the Acolyte to unlock the first learnstone. Each subsequent learnstone requires twice the XP cost as the previous learnstone to unlock.
+1 Rule. For a new level of spell to be attuned to a learnstone (for example, for a 3rd level spell), there must be at least one more learnstone attuned to the level beneath it (and at least one more attuned to the level beneath that, and so on) for each level lower than that level. This is called the +1 Rule. For example, to attune a 3rd level spell, there must be at least two learnstones attuned to 2nd level spells, and at least three attuned to 1st level spells. None of the Dragon’s learnstones may be attuned to a cantrip (level 0 spell).
Knowstones. The eyes of the Dragon are enchanted knowstones (not learnstones) that are always attuned to Flare and Daze. The large red gem in the chest is attuned to Hypnotism. These cannot be re-attuned, and do not count toward the +1 Rule. Like the learnstones, the knowstones only function for the Acolyte while the Acolyte is in physical contact with the Dragon.
Ownership Transfer. Learnstones cannot be re-attuned to a different spell for the same Acolyte. However, an Acolyte may voluntarily gift the Dragon to a new owner. A verbal statement of ownership transfer is required, and the Dragon’s eyes will flash once if the transfer is recognized as willingly given and willingly accepted. This signals that the Dragon is bonded to the new owner. This process resets the Dragon (and the learnstones) for the new owner. If the Dragon is later transferred back to the last previous Acolyte, the previous Acolyte’s settings for the Dragon will be regained. The settings of past Acolytes, other than the last previous one, are unrecoverable. The Dragon will not recognize a transfer made less than 1 year since the previous transfer. The Dragon can recognize many somatic variations of the transfer commands.
Learning Report. The Dragon has the ability to report the progress of the Acolyte to the Tutor, or to the last previous owner. To report, the Dragon must be in the presence of the Tutor or the previous owner, and must be commanded by the Tutor, or the previous owner (whichever is applicable) to report progress. It can recognize many somatic variations of the report command, and can discern whether the command is given willingly. When the report command is recognized and accepted, the eyes of the Dragon will flash twice. The recipient of the report (and the Acolyte, if present) will enter a hypnotic state and receive semiconscious knowledge of the Acolyte’s progress. This will take the form of visual vignettes of the Acolyte’s spellcasting attempts of the attuned spell(s). The Dragon will attempt to include at least one success and one failure per reported spell. Vignettes last 64 seconds, and the storage capacity of the Dragon is 16 vignettes. For each learnstone that has been attuned to 100% success by the Acolyte since the time of the last report, the Acolyte and the Tutor (or previous owner, if applicable) will each receive 10% of that learnstone’s unlocking cost in XP. Reports may not be repeated, and Tutors may not receive XP for reports on learnstones that they did not assist in unlocking.
Ownership Record. The Dragon maintains a database of all past owners (text only, in 8 languages) and will recite them to the mind(s) of those present at the end of each learning report (the Acolyte, Tutor, and/or previous owner). The current list includes 8 of the past 11 High Chieftains of Yarptice, and 25 others, 18 of whom are from the royal house of Yarbin. The most recent five owners are: Vinon (prince of Yarptice), Yuroth (High Chieftain), Runhist (prince of Yarptice), Maton (prince of Yarptice), and Topor (protector of the house of Yarbin) (parenthetical notes are not included in the record, but are given here for clarity).
