Lord Vanaduke
You'll need to update your JK tutorial for post shadow t2 Royal Jelly version.
I do like your vanaduke one though. Only thing that bugs me is the silly "100 CE giveaway thing" lol. Definitely 100% dropped a like on it though its good =)

I have Tutorial Guides too =)
You can generally see the strategy behind the kills and that in itself is a guide. I have....
2* gear kills (Just wolver set, bristling buckler/owl shield, calibur) of Snarb (clean 40 seconds), Prenerf RJ, New RJ, and twins.
Flawless Victories (The cleanest kills of bosses ever done on SK) Currently Snarb, Twins, Prenerf RJ, New RJ, Vanaduke, and Ice Queen.
Jelly Palace Guide (D15, D16, D17 all done in my 2* gear set)
0* gear kills (Just default 0 star set, Proto Gun, Proto Sword, Nothing else) of Snarb, Twins, and the New RJ!

***My original intention behind alot of these videos is the complete lack of an effective guide. Especially a few months ago when I started playing...I first looked for a Royal Jelly Guide and found NOTHING beyond "Just zerg it with poison, shadow, vials etc"
