Metagaming is using Player knowledge that might not necessarily be character knowledge.<br/><br/>An easy example would be your Character switching to a Damage type  that bypasses a creatures resistance or deals double because you looked up the stat block online.<br/><br/>Yes it is their turn, but I want to give Redknight the chance to spread that damage out like he intended but I misunderstood...or we can leave it like it played out.
