In our race to see who could complete their goal first: For you, to release the missions system; and for me, to beat the Royal Jelly using only piercing weapons. I'll admit you put up a good fight, taking it down to the wire with rolling the missions out on the test server, but to the victor go the spoils.
Attempt 1: Nope...
Attempt 2: No sir...
Attempt 3: Third time lucky!
Some amusing stats: With the gear I was running I could do a maximum of 13x15 (195) damage on a single charge. For comparison, each mini heals for approximately 57hp. The DBB does 24 damage each hit, but is luckily very effective at keeping the field clear of the minis. 2 mist revs and 1 health split were used during the battle, which took a remarkably short 4 minutes and 27 seconds from end to end.
As far as I know this is the first and only Royal Jelly kill with only piercing weapons (at least since the October patch, when his royal pinkness became a real slime). Props to Meowcennary for helping me out on the final attempt.
