It's Berserker, not Bresker ^^
Though I would suggest not getting Aura of Haste / Blazing Strike if you're aiming for Mercenary. Blazing Strike has a cool animation, but random damage and does low-mediocre damage without really low DX (Like -10). And once you have Bunny skills, you won't really use it.
for more Buffalo hotness <3
