I thought the whole point of 4e's monsters were that you don't have to equip them. Perhaps this is why people are saying 4e is too easy? They forgot to add crit damage![]()
Generally no, they don't.I lent my books out and my DDI sub ran out so I can't answer this basic question: do monsters get extra damage dice on crits like PC's do?
A few monsters also use weapons that have the high crit property, like greataxes. I believe, if you look at creatures like orcs and the bodak reaver, you'll see they do extra damage on a critical as well.
Some (a few) monsters do have irregular critical damage, but then that's noted specifically right beside the power in question.
Don't add the enhancement bonus of a magical weapon to the attack and damage values of monsters and NPCs. And don't sweat it if you forget to use any special powers or properties of the weapon.
That is, the monster gets the weapon, but unless it crits, there is no difference in how it operates. Its only when the adventures loot the item that somebody will get the benefit of its enhancement bonuses.
