Touhou Project

The autocollection border:
its a mechanic introduced in touhou 6 that makes all items be automatically collected when your character is at maximum power. since touhou 10 it was tweaked into autocollecting regardless of power, because of the fact that getting power items is harder from touhou 10 and up. its invisible and its located at the top part of the screen, its measured at 1/5 of the screen, while playing as Marisa
Kirisame, its measured 1/4 of the screen.

The spirit world gauge:
its a mechanic in touhou ten desires that amps your attack power up to eleven, makes you invincible to bullets, and some characters have different features related to them.
how to activate: press the trance mode button when your spirit world gauge is full. otherwise get hit while having the gauge 1/3 full, although you will die afterwards.

The divine spirits:
Divine spirits are dropped by defeated enemies, as well as bosses after defeating their spellcard. In addition, bosses will continuously drop blue and gray spirits while they are damaged. The rate at which the spirits appear increases the closer the character is to the boss. This can be anywhere from almost none at long distances, to 3+/second when the character is very close. Any enemy in the game can drop blue and gray spirits, while green and purple spirits are dropped by specific enemies at predetermined points in the stage, as well as after each boss' spell card (excluding their final spell).

Collecting a divine spirit will fill the trance gauge slightly. In addition, each type of divine spirit has unique effects as follows:

Blue: Adds +10 to the players point item value (+100 while in a trance state).

Gray: Acts as a point item, granting points equal to the player's point item value. Fills the trance gauge to a greater degree than other spirits.

Green: Adds +1 to the players bomb meter (+2 while in a trance state). An extra bomb is awarded for every 10 bomb points the player collects.

Purple: Adds +1 to the players extend meter (+2 while in a trance state). The first extend is granted at 10 extend points, the second at 15, the third at 20 and so on.
