path of frost (dk ability) makes you and ur party walk on water, but if you dont like some people in ur party or u just feel like being a dick you wait for everyone or that one person to jump off a cliff into water and hit path of frost and they will die when they hit the water.
u might say, when can u use this !!!!
well in many instances when u finish you usually jump down into water to go to the exit fast like in utgrade keep, pop a frost as someones falling and SPLAT
not very usefull but funny and fun if someone in the group is bothering you
have fun
