I tested in more than 10 battles.
The results i am getting is that the move description in turns is completely different in actual gameplay.
1 turn Shield and two turns buff.
The only way to follow the description is if i encounter slower Dino( ) or if i speed boost the low legged Croc to a Nitro Croc.
Unless they make the move a priority move. Furthermore it does not make damage as a move,so priority is kinda preferred.
But i would like to test it yourself and tell me your opinions,because i can be wrong.
