How to unlock the Calcium Deficiency achievement in Craftopia - Definitive Guide

Bone Dragons are located on Desert Islands. Bone dragons only "activate" when you're close by (within few feet). I believe you can find them on desert island level 4+, these dragons are usually around level 108 so, be warned. There are 2 types of bone dragons, fake and real ones. The real ones look a bit more destroyed. Walk up to a bone dragon and if it doesn't wake up it's the fake one.

As pointed out by Jay Cowl if you die go back to where the dragon was, its health does not reset.

It also doesn't matter if you use magic or swords, as long as you hit its core.

If you're struggling with the fight here's my one shot build (Deals about 60-70k per hit)

2x 400+ ATK weapons

Combat skills:
Charge strike - lvl2
Battle hymn, dual wield, berserk, backwater formation, unstoppable, lai slash - all max lvl
Lean force - lvl1
Wild Might - max level

Before the boss room eat raw meat and apply all 3 buffs, come up to the boss and use Lai Slash, boom 70k damage. Warning you're extremely vulnerable with the buffs on.

I found my first one in the hell biome but it was way too hard, found a bone dragon in the desert after killing the red dragon on the mountain. You can tell the difference if it’s real or fake if it has so many more bones under the main skeleton

Should also be noted they are resistant to physical damage. I suggest specing into magic with lighting and meteor attack. Straight north of the spawn is a village on top of the mountain. Purchase foods that have 15-30 second cool down with 350 HP heal. Whole fight took about 15 minutes. If you die you'll revive back at the spawn and can run back with his health being the same.

is there some kind of trick to getting these guys to spawn, i've looked on like 5 different desert islands and i haven't found one. is there a minimum or maximum level that they spawn at or do i have to clear all the dungeons on the island or something it's really getting annoying.

@Doomed Saint load up a level 4+ desert island and wait around for say 5 mins, then run around and you should find it. I've noticed it takes about 5 mins for the dragon to spawn

Well, I have 8 desert islands from lvl 3 to 7 and I have never seen a bone dragon yet. I go in one, spend a good 20 min there, fight 2 or 3 red dragons but cannot get a single bone dragon to show up. 3 hours of that yesterday, dozens of red dragons dead and no bone dragon. Am starting to wonder if they exist on xbox...

edit: Well, maybe i should have ranted earlier cuz my very next try after this post, i found a bone dragon laying on the beach and gave him the beating of his life :)
