Heroes 5.5 WarGame Edition - Tactical Edition.

Secret Revelation: The hero gains +2 to Sorcery and 1 random spell of level 1-3.

This is complete garbage compared to Wisdom and other perks. I definitely wouldn't take it.

Cursed Land: When moving, non-flying enemy units take 3 damage for each level of the hero.

This is also not very useful compared to others.

Secrets of Destruction: The hero gains +2 to Knowledge and 1 random Destruction magic spell of level 1-3.

It only makes sense to take it if you're playing a Warlock, and even then, only if you're really lacking in artifacts and wells.

Is it possible to make an enhanced version of Divine Retribution available for Warlocks as well, and to make the Phoenix Cloak and Pyrokinesis also apply to this spell? After all, it deals fire damage.

Secrets of Destruction: The hero gains +2 to Knowledge and 1 random Destruction magic spell of level 1-3.

In my opinion, it would be better to increase the damage of all spells by 10% instead, for example, and maybe add magic penetration.

Everything else seems fine
