desert dungeon drops normal slab fragments, ice region drops libero slab fragments volcano dungeons drop both.

can be combined at primitive workbench or higher.

The green slabs combine in a ratio of 4 to make a pruple libero slab that purple one summons.

I had a bug where they stopped appearing in the crafting bench, I thought I was going crazy, but they came back after I approached the bench again after a few minutes.

I kind of wish they just made it something on the ancient tech tree - cause I dont like it that it keeps appearing and disappearing on my workbenches. Have to restart the game or delete some files, re-verify, then it works once.

they are looted from gold and above chest or dungeon chests, pretty get pretty much at least 1 from the ice biome dungeons.

you need 4 slabs and combine them at the assembly line II

For normal boss -- You can find the frags in any dungeon on whole map. However vulcano, big dessert and huge mountain area dungeons only drop ones for harder boss.

Its not 100% chance tho. I had to run 6 dungeons to get 4 to be able to summon a boss as final chests when you kill dungeon boss drop those. If you are lucky you can get 2 in single run, but depends on chest quality.

High quality workbench can combine the normal boss, but for higher lvl you will need the electric one.

Also:
DO NOT SUMMON THE BOSS INTO YOUR MAIN BASE AS IT WILL GET DESTROYED...even says in red letters, but people cant read :D

I found them at the sanctuaries

[Grimzy]

Sanctuaries gave the normal slab fragments
Dungeons gave libero fragments
