How to getEdit
Two copies of Assassin's Blade are a reward for raising a rogue to level 2.
This weapon has the highest Durability of all Rogue weapons (aside from while Self-Sharpening Sword) having enough Attack to make good use over time, as long it doesn't get removed prematurely. This weapon is a great target for weapon buffs like Deadly Poison and gives those cards a ton of value.
However, while efficient, its high cost can prove cumbersome. The aforementioned Self-Sharpening Sword can be considered instead, as it costs 2 less mana, and benefits even more from weapon-buffing effects like Captain Greenskin or Doctor Krastinov.
Assassin's Blade is a one-handed dagger dropped from mobs in Shadowfang Keep. However, this weapon does not match that weapon's appearance, and likely simply references the obvious, a blade used by assassins or rogues.
