Ball Test

The Ball Test is part of the Irregular's Test. An Irregular doesn't have to take it. Rather, it is used to test their judgemental skills and how well they know their limits.

Test
The Irregular must beat or dodge the keeper such as White Steel Eel and pop the Ball.

In [http://towerofgod.wikia.com/wiki/Ch._1:_1F_-_Headon%27s_Floor_(1) Ch. 1] Baam is given a Ball test by Headon (the First Floor Guardian). In this test the ball's keeper is a White Steel Eel which is in its breeding season and therefore have not been eating in a month, hence it is very hungry. Both the ball and eel is placed in a area with dense shinsoo. It is noted by Yuri Zahard that the difficulty of the test is to high for a low floor test and that it would be more fitting for 20th floor or higher.

Headon argues that the difficulty is fitting since Baam is a Irregular, but that he will allow for the rules to be bend a bit, and he will accept for Yuri to lend the Black March to Baam.

Other use
An Observer is a modified Ball used by Scouts.
