I dish out some damage with the warpick and usually throw it at an enemy or simply drop it in the middle of combat. Sometimes I throw away the shield too or use it to grapple, like topple an enemy and then use the shield to pin them down as a ‘grapple’. I try to flavor it differently, depending on combat situation, as not to make it too boring for everyone while just going “Imma grapple them”.
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.
