Hey, if a part of the name is in latin, why not the whole thing? "Corona Ampli Ateris Iridis" if I am correct... I may check the dictionary. I pretty much doubt that Nyarlathotep or whatever would speak in latin. I mean, can you imagine Cthulu coming to claim your soul saying "Pacta sunt servanda" ?
Now, Capt'n and Agar have said it plainly enough, but still I must add: I have no idea what a 'Tome and Blood' is. A d20 supplement I suppose. Now, I own the Player's Handbook... and that's it. I have no idea whether and alienist is someone like Ripley, or Mulder, or a girl who is into tentacle sex (you forgot to add that the +2 charisma bonus applies to kinky girls and boys as well,by the way).
This is another item that makes you want it, to keep it, and drives you mad. And costs your soul. It is not bad though. Go to Comment
All in all, this is a decent item, though I am familiar enough with D&D that the details are not a problem. It relies too heavily on system specifics to describe its powers.
The Outsiders Drag Away part I would replace with Outsiders _try_ to drag them away, which would be much more interesting. They might in fact try multiple times until some great confrontation. I would also cause just about all knowledge, spells, etc, gained from this item to be tainted or otherwise problematic. Yes they work, and yes they are powerful, but there are unfortunate side effects to their use.
Tämbourine is firmly placed on my back ,to unsheathe this sword I simply have to say "re clouse" meaning come to me or i can just reach over and unsheathe it the old fashioned way. This sword was created to my liking tambourine is made of raw-like metals I found in different regions as I begun to forge the metals together, I’ve noticed that the raw metal materials were different pieces to a wide variety of swords that were used the past and present, being so most blades have a sheer grey texture Tambourine’s blade became black as the depths of the oceans. The blade expands to 6” which weighs 426lbs the sapphire jewel placed on the tip of hilt (upper middle center of the base) it emits a aura texture of purple which weighs 24lbs the jewel is un-breakable it negates magic for tambourine has a mind of its own only belonging to me it finds a worthy opponents who doesn’t use magic or any type of power to their liking which I can agree with(who would want an opponent that abuses their powers to kill for no reason or to avoid dying by honor tambourine fights with honor and accepts its glory or defeat) I’ve named the sapphire Sophia because not only that its rare and radiant it resembles my burning passion for my love Sophia. I made the hilt to be a length of 15 inches its frame is created with fine katchin (very thick and heavy metal) it alone weighs 50 pounds its texture is black like mixture of, I made it to be a cruciform hilt so it has room for two hands. I I made the blades hilt aprox. 2”, the blade is double-edged but the left side of the swords frame can block and or negate ones attack if needed, it weights 500lbs making it nearly unmovable. To go up against this sword is to quickly find your own death. Tambourine is a twin sword to Terra.
