Evasive: all units receive +1 to speed and initiative before battle (you can make the chance of receiving this bonus before battle 50%, for example, and increase the probability with increasing level) (this is like the Temple of Chance).

Guardian: at the beginning of the battle, the Stone Skin and Evasion spells are cast on the creatures, at the level of the Light Magic skill (you can imitate the Dwarven set on hidden artifact slots).

Specialization: Main Devil: all imps and their upgrades receive +1 to HP (not per level) and +1 to attack and defense for every 2 levels starting from the first (this can be done like this: Ingvar - only for demons, and we change the specialization from Warriors to Imps, and for every 5th level, +1 HP up to each 40th level from the first (i.e., always only +1)).

Specialization: Sandman: all Inferno creatures in the hero's army gain a draining aura (the damage size is suggested to be changed accordingly (in inverse proportion)).
