He only lets me do it when I have one hand free to technically ‘grapple’ and I have to topple/shove them to make them prone. But thanks for the reminder!
I try not to do ‘unrealistic’ grappling and try to use the tools I have to grapple. For example, use the pick to pierce their limbs and keep them in place or pin them down with the shield when prone. But always with a hand free to make the condition to grapple legit.
