Dododex

ARK: Survival Evolved & Ascended Companion

So I’m taking a 146 on on genesis and Dododex says with my harpoon it will take approximately 56 tranq spear bolts and it will go down but it’s ended up taking over 140 and over 50 tranq arrows and he’s only 3/4 torpor. I left 5 secs between shots and he isn’t down. Anyone had this happen to them?
