There are multiple ways to get this seemingly impossible achievement, but this is the only way that worked for me after I looked up and tried different methods. This is a very luck-based and inelegant solution, only attempt this if you have no more self-esteem left after being repeatedly chased across the XL map by the AI and then slaughtered like bleating sheep.


Do this part very quickly! You have mere moments to locate and gauge the AI. Their strength will start shooting up in literal seconds.

If the AI doesn't meet all three conditions, keep restarting. Otherwise,

Throw everyone and their grandma at the enemy AI's gate. Once the gate is down, try to select only your catapults (group select is double click one unit and hope it registers because sometimes this doesn't work). Have the catapults target towers and buildings while the rest of your forces fight. If the enemy has necromancers, try to take them out if you can reach them. Protect your ranged units, don't let the AI through your frontline.

After much butt-clenching and frantic micro-ing, you might be victorious with enough survivors left for the rest of the map. But at least the hardest part is over.

... or is it? My win was embarrassingly bad. I was able to overcome the AI but the other circles destroyed all but 2 of my units. In the end, I only had 1 wizard and 1 healer left alive while the rest of my army was in Circle Heaven. The only enemy units left were these wooden towers inside a water circle that I would snipe with my 2 units, run out of tower range to heal, and then repeat my cowardly assault until all 8 towers were slowly whittled down to nothing, just like my dignity.

Note to self: press the save button once in a while.

I'm not sure if you absolutely need healing mushrooms and monster mushrooms to spawn in order to succeed with Angie using this tactic, but I know mushrooms were present and utilized in my win.

It's definitely not the best solution but I hope it works for you like it (barely) did for me. If anything, you can try it out in between losing the normal and intelligent way since each attempt will only take a few panicky minutes. Good luck and get that 100% already.
