well, actually it doesnt change the of getting a locket, but only one person will get it (the one who reaches it first). so ppl try going solo to get one for themselves. the darkfang shield must be prety rare (and new) cuz ive seen nonoe with it.

I don't know if it affects the original party if somebody goes solo after seeing a love puppy, but I read somewhere about that exploit being fixed so that going solo is guaranteed to not earn you a trinket drop.

Love Puppy trinkets are scaled based on Stratum as any material or equipment drop is. You can get a 1* in any level, 2* Depth 4 or lower, 3* Depth 9 or lower etc. Sucks to find a Love Puppy at, say, Depth 2 'cause any slim chance you have of finding a trinket will only be for the 1* version. Sources tell me there are only two True Love Lockets in existence.

I've seen 6 Love Puppies, most of em in the Jelly Palace. So ya, JK runs would be my suggestion if you want to run into one.
None of them dropped any trinkets before you ask. haha

Good luck, I've seen over a dozen and got one, shortly after I started playing on a Snarbolax level, it's a 1-star trinket that gives +2 health. handy on T1 lockdown, but not much else.

I think it's funny to see the WTB: Heart Trinkets posts, people don't understand how rare they are, and that the price should be over the price of the original Regalia sets.
