So, the PHB has been out for 5-6 months or so by now. What are some of the more common rules mistakes/misconceptions/questions that have come up in that time? I'll start with some:
* You can't combine casting a spell as a bonus action with casting another spell in the same round, unless the other spell is a cantrip. So a sorcerer can't use Quicken Spell to cast two fireballs in the same round.
* If your character has multiple ways of calculating base AC, you only get to use one. Usually you use the best, but sometimes the existence of one method (usually wearing armor) precludes using other methods. So a monk/barbarian could either calculate AC as 10 + Dex + Con or 10 + Dex + Wis, but not 10 + Dex + Con + Wis. If he puts on a suit of studded leather, he can't use either class ability anymore, and instead gets 12 + Dex.
* Subraces are not variants on the standard race. If you belong to a race that has subraces, you get all the traits both of the basic race and of the subrace.
* Totem Warrior Barbarians can choose different totems at each of 3rd, 6th, and 14th level. So you could have resistance to non-psychic damage from the 3rd level Bear totem ability, and round-by-round flying speed from the 14th level Eagle totem ability.
* Unlike the similar abilities for clerics, druids of the land, and paladins, warlocks do not automatically add their expanded spells based on their patron to their list of prepared/known spells. They simply get the ability to choose them as part of their normal spell progression.
Any others that people have found?
