Urgent question On massive boulder

Hi, guys,

( Urgent, because I have only one bag space left, I need to use this skill immediately)

Right now, my boopie has kamikaze, rock fall, earthquake, and boulder.

I just got a massive boulder. So which skill should I replace?

Sould I replace kamikaze?

I'd rather change rock fall than kamikaze.. Most Fire & Electric monsters would be OHKOed by Massive Boulder / Boulder

i replaced my behemoth's kamikaze with massive boulder. I don't see any situation where I need kamikaze and rock fall is usefull in PVE. that's for me though.

Woow u have so many resurrect cards id prefer to replace rock fall.. Kamikaze u can use in pvp as well when opponent changes poke u use it and opponent gets good damage

Boulder is already like Rock Fall so why bother having Rock Fall?

I don't die very often in sealed space expert...haha.

Because I waited a very very long time, and trained my mobs to lv46 or above.

Then went there to finish SS expert. It was not that hard, no cards needed from 8-12, and one card per lv from 13-15.

FC veteran, I stopped at lv6...

And normally, I only farm at lv1 to lv5. I can deal with the enemies quite easily.

Because rock fall has ten pp... In case where potions are not allowed?

This is why you have 4 Mons.

I've never had a situation in pvp or PVe where I used kamikaze on my rhino.
My setup is m.boulder, marytr, quake for PVe. And boulder.

Quake is 10pp and power close to rockfall. For PVe 5 points don't matter much. For pvp every point counts

Massive boulder should go with sandstorm
