Evoland Legendary Edition

Although this achievement is pretty straight foreward, here is a short summary and a few tips.
Travel to the big island north west of Genova after the great disaster. When in the past you enter the bridge just south west of the magilith stone. A scene with Dalkin will unfold, after that talk to him, but he don't want to fight.

In order to persuade him, travel to the future, go to Genova and in the right middle side of the city talk to a guy next to a door of a house. He will try to sell you the house for a ridiculous amount of money. Decline twice and buy it for cheap on his third offer.

Travel to present Genova and go to the same house. Use the key to open it and get the medaillon. Travel back to the past and go to Dalkin, with this medaillion you convince him to take up arms.

Here are some tips on the fighting:
- Use the battle points to upgrade your troops to cavalry, paladins or simple archers. Keep it balanced. Don't spam simple soldiers because the cost will increase. Later on, you can get catapults. Two should be sufficient, don't waste points on a third.
- At some point you can either take the south or north route. Take the north route, which is easier to win and after winning the north route, take the south anyway for extra points. It will help a lot in the final battle.
- Use the protect ability from Dalkin to shield your attacking troops. When moving troops, make sure Dalkin can either jumpin between, or move your troops next to Dalkin.
- Cavalry is strong in attack against archers and simple soldier.
- Paladins have high defence and should be used as a line of defence.
- Keep your catapults and archers at the back
- There is a level where you have to choose between 3 paths to execute an ambush. Pick the most left one.

In the final battle focus on killing Magus. The battle will be over once he is defeated no matter how many other troops are still on the field.
