The Legends of Arkain: The True Story 6.5 - Forged by Iron and Blood 

There is a lot of ground to cover on this map. Enemies drop gold, so it is important to clear as much as possible in order to be able to reinforce your army and stay near the food cap. My personal choice of composition is primarily Executors because they have a small unit model allowing for easier pathfinding, a large group of Priests for Inner Fire and Heal, and a small number of Ironforged for ranged support. In order to get to Lady Elrin, the Power Generator near the Red base needs destroyed, making Red a decent first target. I snake my way there keeping an overall route through the map in mind so as to reduce backtracking later. The enemy bases are all heavily defending and have many many production structures; it is important to push towards the leaders without getting bogged down and stuck, else you will quickly get overwhelmed. It is good to apply Inner Fire at the start of engagements and switch back to heal as to not run out of mana too quickly. Moving to Duke Woras may be the most challenging given how much infantry his base can rebuild en masse. Make sure to have killed enough enemies on the way there in order to have a large enough army to make this move. As I kill a big batch of enemy units, I take advantage of the rebuilding time to move in and snipe the boss. All the other enemies despawn a few seconds after. Sometimes these battles can be a bit of a crapshoot if your heroes end up in a bad spot. Larine can stealth, but Cora may get stuck. The Order of the Tides is next, which is a similar situation where it can very quickly rebuild and keep you stuck in place. AOE on the path is great for enemies to be killed in large groups allowing for short bursts of forward movement. Lady Elrin has Thunderstorm, which must absolutely be interrupted. The pathing towards her can be a challenge to get Cora in for the stun, so I would recommend quicksaving before making a run at this or any of the heroes. I uncover the rest of the pathways through the map and storm Lord Korbaz's position. The neutral Gardener right outside where Korbaz is drops a Rusty Mining Pick. The boss room itself is very dangerous for your heroes as it is virtually impossible to retreat from due to pathblocking. Once all three areas are under your control, General Whitefield's army arrives in waves. It is impossible to save most of the captured buildings, so pick a spot to hold out. Any of the three bases can work as all have a place with a single entrance. I leave a Defender near a Contractor Camp and can reinforce quickly this way even if the building cannot be hotkeyed. This is Cora's time to shine with Flood and Blizzard as huge numbers of enemies stream into my chokepoints. Executors continue to hold the line really well and Priests reapply Inner Fire occasionally. The enemy Knights all thankfully use Charge, which increases their damage taken. I find it is unfortunate that killing Whitefield's entire army is required.

I really enjoyed this map because of how it operates instead usual RTS and feels like a proper sneak attach themed mission

It'll never not be fun to me how the name of this map is so similar to the second mission of the First Human Book (which isn't in the True Story) where Blen and Harmos fight the Ironthunder and Bloodhand clans.

Can someone break down to me Knight vs executor. Which one is the better unit overall? They have the same amount of hp, knight have more armor, much faster movement speed, executor have cleave , higher damage.

Do they make it for reforged graphic?
