General gameplay tactics and its features.

It's not always easier... Besides, you can only see powerful heroes of level 30 after a long game...

sometimes even level 108 :D

Tactical tricks:

-using a Berserk, bring together two stacks of enemy Dendroids; they will attack each other and remain standing motionless until the end of the battle... no need for Blindness - you can destroy both with one spell...

-during a city siege, if the defender blinds your unit, take a Teleport and throw the blinded unit over the city wall and place it near the enemy archer. The archer is blocked, and the computer won't attack your unit as long as you have other troops...

-gates: if you are attacking a city, zombify any enemy unit and open the castle gates for them, or vice versa - take your leftmost unit, bring it to the gates, and leave it to be destroyed by the enemy towers... The gates will never open again, and the enemy is locked in the city - now shoot... You can destroy your own catapult, for example, with Meteor Shower, so that it doesn't make holes in the walls... This is true when the defender has slow, non-flying tanks, and you have an archer...

-it is important to remember that the strength of city towers depends on the number of buildings in the city... The more buildings (including the Grail), the stronger the towers.

A little about tactics. Maybe this isn't an achievement. But it uses one very well-known spell. (On a normal random map, all the not-so-numerous troops were gathered absolutely fairly.) Two simple spells were used: Clone and Berserk. Both are expert level. Hero level 32.

Question: how did you manage to block both archers with one spell? Did you just get lucky with the enemy's troop placement, or did you use the "Resurrection" spell...?
