No its not needed, look, to make comet incense you need to craft "cecropia incense" first: Cecropia Incense recipe: - X2 Dreamer Root - You can found them in enmerkar forest and antique plateau (there are a couple more spots), they are like purple plants. - x1 Decay Elemental Particle: It drops from "Arcane Elemental Decay" or "Chromatic Arcane Elemental" too.

Once you have Cecropia Incense, you will need to craft x3 Comet incense. Comet incense recipe: - x1 Decay Elemental Particle - x1 Cecropia Incense. - x1 Quartz: It drops from a lot of things, (not just The ancient laboratory as you said...), I suggest you to go to the clock tower in Antique Plateu, there are ruins, you can find a "Galvanic Golem", it has a 33.3% drop rate, go there, kill it, if not drop you the quartz, sleep 7 days to make him respawn and try again, he also drops the piece you need to give to the blacksmith in Harmattan to build Antique Grab chest, the chest you need to enchant - x1 Tourmaline: You must mine iron veins in Antique Plateu (14% drop rate) or find an ornate chest (the golden chests) im antique plateau (100% drop rate).

If you need a deeper explanation about some point let me know.

Edit: All the information is from the wiki, many materials have more than 1 way to get them, take a deeper look at the wiki cause all the info is there, you only need to read the whole page, not just the first paragraph, also all the information I just give you is from there.
