Place the following text as a sub-rule in Daemons.

Ifrit

Summoning Cost: 3

  As a Daily Action, the employer of Ifrit may pay up to 4 pairs of souls to Ifrit. Then, in the GNDT roll, 1DICEX, where X is the number of souls paid(total souls, not pairs), plus one(1). They may then target any corporation who has more souls then they do (after souls have been paid to Ifrit) and remove souls from targeted corporation equal to the result of the dice roll.

More clear wording, and use of Daily Action instead of Daily.
