I think it’s like rust idk. I don’t play ark😭

It's a pipe bomb.

These pierce titanosaur's resistance (at least on mobile) and doesn't make it mad

However i don't recommend killing a titanosaur with c4, as it would take over 400 due to the fact that you can only place 50 c4 at once then explode it and start placing again, and the titanosaur's high health regen will cancel some damage as you place down another 50 c4.

Boom 2nd! Put these on your friend while their sleeping.
