"Built for quickly bringing down and finishing off opponents with frightening efficiency"
The Ambusher's Hacker has by far the lowest requirements of any epic equipment, needing only a max of level 37 in blacksmithing, and a relatively low 30 in engineering to craft. It's probably the only epic recipe that will be craftable upon unlocking it—most others will demand additional weeks after unlocking in order to catch up to the requisite crafting levels. Furthermore, the Ambusher's Hacker offers great stats and bonuses for aggressive heroes. This makes it an appealing early investment for a powerspike if one plans to use a lot of the Thief or Barbarian. Just be sure to start researching prior one-handed-hacking weapons early because that crafting line takes over 2 weeks to grind through, much longer than any other crafting line.
In spite of these great advantages, the Ambusher's Hacker lacks crucial bonuses for an aggressive weapon, like a damage type bonus or an armor penetration bonus, which all the best late-game weapons provide.
Ultimately, the Ambusher's Hacker is outshined by its tier 2 counterpart, the King's Hammer, whose supportive nature synergizes perfectly with higher-priority meta heroes like the Warmaster and Cleric, making an already first-rate tier 2 epic weapon even better.
