I use Managarmr to tame Acro. Use high health if not accustomed to taming this way. (Mine have 6k health and 2.3k dmg which is way too much) Use Ice breath in burst to know how much dmg you are doing. Tek binos make it easier. After the first initial feeding. The rest of the process is fast and simple. Ice breath til low health or until it roars. Rinse and repeat. Knock back doesn't effective mana as much
