Mod: Spell name for Moloch's summon imp(continual)

[Xietor]

Has anyone run across the spell name or number for the spell that allows for the continual summoning of imps during the combat? Adding a few #onebattlespells to some throne of heroes and wanted to add this one without diving into spell modding.

In other words, in Throne of Heroes I am limiting spells to those already in the game.
