1 Angel vs. 250 Magogs – Heroes 3 Complete
You must be able to block 2 Magog stacks immidiatelly (Tactics skill). Cast Shield immediately. Cure when needed.
Always position the Angel between 2 stacks and always attack the lower one so that you retaliate to the upper one and attrition them steadily.
AI will not attack if it will damage itself. Therefore Magogs will not fire for they would kill their own.
