GRRR...

Grrr... I need to beat the stupid submarine shrine boss or else i won't be able to play the desert stages. Tips? I'm lvl 35. I have a sniper, sniper, priest, and a mage.

I managed with my sniper shooting poison arrows w/bullet card, my magician shooting ice to slow the beast, my boxer hitting w/onigiri equipped gloves, and my priest helping stats w/ a long wooden staff.

I kept my party auto-walking, but manually spread them out so only one would get frozen at a time. I think that my magician slowing was critical, because that slowed the rate at which attacks came at them.

My party members did each become frozen at some point, but by spreading them out only one was frozen at a time. My boxer's gloves dropped enough onigiri that after a party member would become un-frozen I quickly dragged him over to some onigiri for healing, and then back to the action.

You might be able to do something with similar by equipping one of your snipers w/ poison, and the other w/ quint or quad with an onigiri card.

Get a poison sniper with the catapults card (v2: "Cavern 1" 5%, v3: "Submarine 3" 1% droprate). If you have full MP and Catapults v3 you can add an Emerald v3 (Green Gel Wheel, Mist Groove 3) else add a nice Peridot v3 (Green Gel Bat, Mist Grove 1, 2%).
The catapults card is the key here. It makes the fight that much easier. Disable all your rangers auto walk (except of one sniper perhaps) and only use that one to attack. (So you only need the combo above once.) If he dies, use the other one and give him the stuff. If he dies too, revive one. Keep the other two at the beginning, so they don't die.
Also you might want to restart if the Boss does not spawn to the very right, because its easier to keep the rest team alive if he is not in the middle.
If you use the Emerald, you have to poison him about 200 times, if you use the peridot around 100 times (full 4 seconds) is enough. So if you can get enough shots in (catapults v3 and full MP) use the emerald, else its probably easier to use the peridot.
If you want to use the rest of the team... I recommend Big thunder, catapults card and perhaps a black stone 3 (if you don't have 30 dex) or purple crystal perhaps... but seriously don't.
*edit* Oh and you probably need a little cash for reviving... In my first go without the catapult I used 80k Gold for revives. The second time with catapult it was around 10k, but I also had to pay a lot less for the revives then (came from 100k).

Get a ton of money and whenever your people die, revive them

I wonder if the game keeps getting updated soon this boss will be as easy to kill as castle

[Qwerty]

...Except the game doesn't seem to keep being updated soon. It seems that it's schedule has slowed to that of PG.
