Silica Needed to get Old Habits

[Baldur93]

I almost completed all the map. All elephants are killed and there are just few question marks have left (mostly not far from Cyrena). All tombs are completed as well. But it so happens I have only 39 silica now and I need 50 to unlock Isu device under Sphinx, which hides that armor. Any ideas where to get additional silica?

You must have missed a bunch in the tombs. Go back and search them more thoroughly. Be sure to use that sense scan thing to highlight hidden areas and caches. Spam it, every few seconds. Keep your head on a swivel, look up and down too. Any marked pick up, find a way to it.

I believe I got about 60-65 from doing all the tombs.

This points to 65.

Success. I scouted maybe 5 or 6 of tombs and found more silica, so I had exactly 50 on me and activated the mechanism. I will get the achievement soon. Thank you.
