My level is 39% prodigious, I have 500,000 gold, the depth charge, rocket booster and ice cubes. My pneumatic spear is a level 62, but I can't catch any octo tentacles... they haven't shown up. Any and all help would be appreciated... I have read the Icelantica Quest wiki and can't find anything I have overlooked.... suggestions??
I'm not 100% positive this will make a difference, but do you have your rocket booster activated when fishing? I just purchased the rocket booster (had the depth charge, ice cubes, lvl 19 pneumatic, 56% prodigious) I have the booster activated and I've pulled in 2 tentacles in about 10 casts.
Hope it helps, and good luck! -Steve
