I have an elemental lightning ptero, an elemental poison ptero and an elemental lightning tapejara but when I try to hit prime dinos in order to put them unconscient the torpor does not go up. I even tried with arrow but i simply cant give torpor to them.In every other dinos it works just fine, and when i searched it all the videos i found about taming primes they just attack with the lightning tapejara and tamed it.Help me please.
