Yes it's possible, unfortunately it's also possible for your RNG to be that bad.  Especially now with the number of factions in the game.  I know it's frustrating but keep grinding and you'll get one.

better yet, but the 10 revenge accessories from the clan shop every week. You're guaranteed epic or lego, 5 or 6 stars.

Even if the counterattack bonus is small, or even if it doesnt even fit your charaacter that well, most times its easier to get good jewelry from there than in spider dungeon.

I hate to ask this, because I know what the answer is going to be, but - what stage are you farming? If it's anything under 16, you're really wasting your time - the amulet you get, if and when it drops, will almost certainly not be worth investing into.

yeah, i love this. i think this is just gonna be the best value for clan gold early on, as well. 

and to OP, it's very much as Short said. 

Due to there being 15 factions that each have 3 different accessory drops, we could be waiting a long, long while on specific pieces.

im not trying to get an amulet that im going to keep forever or max out, im trying to complete the champion challenge for puting all 3 accessories on a champion. and as far as accessing the clan shop goes the clan im in is only lvl 5. and it seems to be the case that most of the clans of higher level are constantly at full capacity or not willing to take in newer players, which is understandable.
