Love this game, though it gets easier as it goes along. I had some trouble with Little Johnny, but one-shot HAROLD and Goddess Helena. You can take down Helena easily by practicing on the statues in Gideon Park - she's much the same. I zerged HAROLD.

Does anyone know where the third delva echo is? the archievements says it's three

same location as the alpha, just have to re-enter the area

The missed the beta delver and all gamma beta alpha delvers can be skipped

Got a heavy duty called hot-n-heavy from the kraken dlc first boss. got it mark 17 with 694 dmg, I'm in NG+, 24 impact, 110% atk speed, +70 energy gain, 134% stamina consumption, 28 fire dmg. I went for a standard target right arm and sever. Don't think it's his hardmode weapon though. also for starts he is heavy and slow hitting and found him easy to parry. got a spear called Ungula Universalis from the second boss. Mark 18 with 894 dmg. 12 impact, 98%atk spd, 20 enrg, 87%stm.

I just recently discovered a Delver Echo Beta in the Underground, while following Eli's Path to the C.I.T.

18 bosses

So. You can make it to the Command place without fighting Eli & Johnny and likely the Captain. I *assume* you need to fight them to access areas you need afterwards.
