[HoMM V]9 Race - Swamp! Is it needed?

Warlord - Worshipper - because among us, the Lizardfolk are like a sect.
Skills:
Shamanism - allows learning rituals and spells.
Soul Steal - allows stealing the souls of several warriors from enemy units - they will die, and the warlord and mages will gain additional mana, and other units will receive a small bonus (once per battle).
Fanatical Fury - a kind of self-sacrifice: the unit enters a rage (for a few resource units) and deals more damage, has higher initiative and speed, and defense; however, when the effect ends, most of the unit will die.

When I was talking about sects, I meant not idol worshippers, but less bloodthirsty creatures.
Maybe then, Shaman.
And what rituals will they perform? We have the ability to perform rituals.
