Is there some trick I'm missing to the Royal Jelly? I've got all 4* gear, a Vile Striker WITH a low damage bonus vs Slime, and it just seems I can never take the Jelly King out. After everyone uses up all their vials, we're still sitting there wailing on the JK with no progress (most of the time my sword won't poison him at all, but I take one whack at a passing little jelly and it's poisoned...), and then he just starts spinning non-stop. He'll spin around the room, stop for about 2 seconds, then spin some more over and over and over again until the whole party has wiped.
Myself and two (capable) friends just can't seem to beat him. Clearly there's something we're doing wrong, any ideas?

If you pack a lot of normal and piercing, it could work. The best gear to take out JK in my opinion is the Virulisk set. Don't rely on Vile Striker to do the poisoning since you can barely hit JK. Use a bomb or just don't waste your vials.
The poison bombs aren't worth using. Their poison is minor, so it doesn't last more than a few seconds. It's also tough to charge a bomb in a room as crowded as the JK fight.
Bring poison vials and use them judiciously (don't throw one if he's already poisoned). Also bring fire and curse - as many as you can. If you don't get a ton of curse (likely), people who don't have curse vials should bring shock. Stack the status ailments so you're preventing healing and doing lots of damage at once. Then just wail away with your swords. Don't bother with other weapons except perhaps setting off a bomb to clear out the little guys while he spins because only swords can do enough damage.
What are your other two capable friends doing?
