Artifacts, like heroes, weeks, and other bonuses, now have a much smaller impact than in previous installments. But it's still better to have them than not to! Even now, one of the most useful artifacts is the "Unicorn Horn Bow." Shooting without penalties is still relevant, especially since the horn now also provides a damage boost. Necropolis starts to dominate even more ;).
Artifacts that provide a "+" to stats now have almost no effect on troops. Instead, they significantly enhance the hero's direct attack and magic! And now, magical power and magical defense also increase the hero's mana, so for a mage, such artifacts are a must-have.
Dynasty weapons provide much smaller bonuses than even "Strong" level artifacts, but they remain permanently :). And the "Staff of the Eight Aspects of Ashi," which is unlocked with the expansion, provides a good boost to both mana and magical power!
