Who has enough powerful magic.

It’s best not to deploy Furies in battle if you’re playing against spellcasting and ranged units, unless you know they won’t go first, won’t reach their target, or won’t be able to eliminate all of them in one attack. Also, avoid deploying them when capturing a castle. Furies are an easy target for towers, archers, and spellcasters. But when there are no such units, Furies are really effective. Boots that give +1 speed to all stacks in your army are also desirable.
