Robin Hood - Sherwood Builders

If anyone needs help with getting achievements, here is my 100% Achievement Plan for Sherwood builders. This particular achievement can be found at 13:16 in the video

You will need to strike (default ) an enemy with a sword, while crouched from behind, to perform an insta kill. At the start, only enemies at or below your current level can be executed (red skull icon); those who are above your level will just take a large health hit (knife icon), but survive and immediately engage in combat.

You can generally find a few easy targets at the various enemy camps and warehouses, or patrolling the road, where the use of the tall grass allows you to approach unseen. You can find some stationary lookouts, which are easier to get behind, but most are patrolling a specifc pattern in the area; observe from a safe place and plan an approach.

Your crouched movement speed is barely faster than the enemy's walk speed, so timing can be tricky at times to cover large distances before the target either moves again or turns around and spots you. Try to close the distance as best you can using cover - tall grass, trees, buildings, crates, etc - before going for a moving target. Shooting an arrow at a jug or other breakables found around the camp can help get you the opening needed to reach your target as well.

You can increase the enemy execution level by up to +3 (you level) with the acquisition of each of the 3 Bloodlust skill nodes, found in the Path of Shadows skill branch.

Other skills and armor can help reduce visibility, allowing you to remain undetected as you approach a target. Additionally, the time of day and movement speed are each factors at work as well. Being spotted or attacking an enemy with too high a level will quickly get you outnumbered and lose the chance to backstab others in the area.
