The following items representing in the images are required:
1. Buy an Animal Courier, spawn it.
3. Buy & give flying courier recipe to Animal Courier, make sure you don't use it.
2. Buy Ring Of Protection and drop it.
3. Buy a Sobi Mask and drop it.
4. Move your Courier a little bit away from you so you don't face problem doing next step
5. Now select Animal Courier, Hold [shift] (queue command), pick Ring Of Protection & Sobi Mask using [right click] and then immediately select the courier and upgrade the Animal Courier into Flying Courier using [left click] and release [shift].
6. If the step #4 goes perfectly, the Sobi Mask and Ring Of Protection both items you picked up using shift (queue command) will not form Ring Of Basilius.
7. Now, make Armlet On Mordiggian on your hero.
8. Give it to the Crow!
9. Now activate it :)
10. Bah.. A Fatal Error :@
After having so many bugs in DotA 6.66b like PitLord's Firestorm bug. We hope that IceFrog will soon come up with a solution releasing DotA 6.67 map, which he has mentioned before.
