Hmm, chest > chest > fish > timed out is a little too fast. By right, you should be able to pop 3x chests and 1 monster before timing out[ i.e you should be able to cast 4 times without any trick] . Even if you manage to get the 3rd chest, it won't be a ring. Probably it has to do with reeling/tabbing technique and of course you still need to use the pugil's trick to get the ring.
