Use of Powers - Player Description

Players need to briefly describe how their Power works in-world for the Power to be effective. This is particularly important if it looks as if the power would not work in those circumstances - knocking prone a Huge creature or an ooze, or creationg Visions of Avarice treasure when the enemy are mindless undead. A notably good description may gain a bonus on the attack roll - +1 or even +2 if exceptional; a marginal one will typically give a -2 penalty; a completely ineffective one (illusionary piles of gold to attract dire wolves) will cause the power to fail. Players should take a bit of time to think about it before their turn comes up so they can give a good description immediately on their turn. 

Use of skills, movement also need to be briefly described in cases where it is not obvious what's happening. Again, a clever description can give a +1 or exceptionally +2 on the check.
