Good morning gamers,
I have always been a HUGE fan of the magical powers in MESBG and how the system of casting and resisting spells works. The rules for casting and resisting hasn't changed much since I got started and the only additions that were made (Heroic Channelling casts a spell on a 6 now and you get Will points back on resist tests that get a natural 6) have been good - and I think the change to Channelling was epic in this edition. The purpose of today's article isn't to go in-depth into every spell - we'll be doing that in a later series - but rather to explain how casting works, things to think about for different caster types, and how to pick the right targets for your spells. Furthermore, you should be aware that I'll be using the term "spell" and "magical power" interchangeably in this post (and have already done so in this paragraph). Let's dig in!
How It Works: Casting and Resisting Magical Power in MESBG
Casting got both harder and easier in the new version of MESBG. This is partly due to the change to Heroic Channelling, where you spend a Might point to "get the spell off on a 6" (more on that later), but also the casting difficulties of most spells went up (nothing is cast on a 2+ anymore and many spells are cast on a 4+ or a 5+). While the casting difficulties went up (and many people would say this had made casting magic harder - and it is now), the fact of the matter is that magic itself got stronger in this edition of the game - so learning how to use it is definitely a good idea. We'll see why magic is so good at the end of the post.
In order to cast a spell, a model with at least one magical power has to be unengaged in order to cast one of its magical powers (though there might be a list that gives its members the ability to cast some of their spells while engaged). This means that if you can charge an enemy caster before they get to cast, you can prevent them (most of the time) from being able to cast a spell. Perfect!
As you probably noticed in the statements above, each model with at least one magical power can only cast one magical power each round (though again, there are models that might plead an exception in certain army lists). Since many casters have access to more than one spell, they have to be selective and intentional with which spell they're using this round. It's often a good idea to figure out BEFORE you play a game what spells you intend to use and in what situations you intend to use them. For casters like Moria Goblin Shamans, this may be decided pretty easily (I'm casting Fury with two dice and then I'm done OR I'm channelling Fury and will save 1 Will for a one-off use later), while casters like Ringwraiths and Wizards might require an entire chart to figure out what spell you're going to cast. Experience and practice helps with this a lot.
