5 Challenges Blaster Casters Need To Prep For (in Pathfinder)

I said it myself back in Vulgar Displays of Power: Tips For Getting The Most Out of Your Magic in Pathfinder, but blaster casters often find themselves getting less bang for their buck when it comes to an effective use of magic. With that said, there are few things more satisfying than pointing your hand, barking a word of power, and watching as the troll's head explodes, or a rain of fire destroys an enemy squad.

If you want to be an effective artillery piece, though, there's a slew of things you need to keep in mind when it comes to what your enemy can do, and the challenges you're going to face with regards to your effectiveness on the field. Because it's tough enough channeling the destructive powers of the ether... there's no need to do it with a set of ankle weights on, too.

Challenge #1: Energy Resistance


Is that fire damage? Oh... that's too bad...

There is nothing that is a bigger pain in the rear than charging up your big gun, only to find that the enemy is going to knock between 5 and 10 points off your damage. Or, worse, that your enemy is immune to that magic because of the element you've chosen to use. This is the most obvious pitfall out there, and a lot of players are rolling their eyes reading this, but I've seen this scuttle blasters' effectiveness more than once with players who go all-in on a given element, and then find by mid-level that they're essentially casting with one hand tied behind their back.

As such, it's a good idea to make sure that you have a wide variety of tricks up your sleeve. Like I said in 5 Challenges You Have To Deal With in Every Pathfinder Adventure Path, that means you need to have several elements you can call on. Fire is the most common resistance to find, in my experience, but cold is right behind it, and electricity and acid comes along behind that. Sonic is rare to have resistance against, as is negative energy, but there are some creatures that possess it.

Whether you choose to keep a wide variety of spells on-hand, or you have a trick that lets you convert and change the energy descriptor of a spell like the Elemental bloodline does for sorcerers, this is going to be a primary issue you'll have to deal with from relatively low levels.

Challenge #2: Evasion and High Saves


Did you just throw a fireball at me, you pleb?

Area of effect spells have the same satisfaction you get from dropping a sledgehammer on a problem. And when they work, hoo boy do they work... but when they whiff it can take all the wind out of your sails.

Which is why it's important to use these spells in situations they're geared toward so you get the biggest possible impact.

Area of effect spells (fireball, lightning bolt, and other classics) work best when you are dealing with hordes of creatures rather than single targets (and are supremely effective against swarms), and when those enemies are in a formation that gives you the biggest bang for your buck. Because if you roll 10d6, and hit about 30 damage on a given creature, that's not a lot of harm done... unless you did it to a mob of 10 monsters, in which case you spread quite a bit of damage around! The problem with area of effect spells is, of course, that a monster takes half damage on a successful save. And if they have evasion (or worse, improved evasion) then you're just throwing around fireworks for all the good you're doing.

The key is, again, variety. While you should try to jack your save DC as high as you can get it (I covered a lot of options in How To Increase Spell DCs in Pathfinder forever and a day ago), you should also have plenty of single-target spells that don't allow for a saving throw at all. Because that trio of rogues might be able to laugh off your fireball, but a scorching ray at your full power, or a bevy of magic missiles, is going to put them in the ground before they can get a chance to pull out any fancy tricks.

Also, don't keep hammering away at creatures with high saving throws that keep besting certain spells. Change tactics, and attack a different defense (their touch armor class, their Fortitude save, etc.). You need to attack their weak spots, not slam your fist into their strong defense and hope you get through.

Challenge #3: Spell Resistance


Fool! You have no power here.

Spell resistance is the absolute bane of blaster casters. While it isn't usually an immediate issue when a campaign starts, it's going to start cropping up as soon as your campaign deals with outsiders, dragons, and other powerful monster types... so you need to be prepared for it.

The first thing you need to do is boost your caster level as much as possible, and to take feats like Spell Penetration to be sure that spell resistance isn't an issue when you decide to cut loose. There are also rods that give you bonuses to overcoming spell resistance, and keeping one of those on your belt is always a good idea.

With that said, it is equally important to make sure you have at least a few spells up your sleeve that don't allow for spell resistance. They are few and far between, but they do exist. A lot of them aren't blasting spells (glitterdust is a perfect example), but you need to keep your options open for when the other bullets in your gun aren't going to get the results you want.

Challenge #4: Sight Lines and Effective Firing


Got you, you little bastard!

One of the simplest ways to take away a blaster's ability to affect you is to vanish. Whether it's into a cloud of smoke, by turning invisible, or ducking behind total cover, not having a line of sight/line of effect to a target can stymie you in some of the most frustrating ways. And it's going to happen sooner or later, so you need to be prepared for it.

If you have darkvision then you're already one step ahead of the curve. However, it's a good idea to invest in an ability to see invisible creatures, and if you really want to throw a monkey wrench into their gears use spells like the previously-mentioned glitterdust to mark them out for the rest of the party. Invisibility purge is another great trick to keep up your sleeve, though a simple smogstick is also a useful, alchemical solution to the problem. You should also keep gust of wind on hand, or consider investing in fogcutter lenses, or a goz mask, as both will allow you to see through fog, smoke, etc. Of course, these would also allow you to pop smoke yourself with an obscuring mist spell, and to fire with impunity at enemies who can't see you.

Just some food for thought, there.

Challenge #5: Actually Dealing Damage


These numbers just aren't adding up...

One of the unfortunate truths about blaster casters is that they just don't pack the wallop you want them to... and this only gets truer as you go up in level. As such, you need to tweak your load out to make sure that you are getting every point of damage you can out of your spells.

For example, a higher effective caster level (such as how the Sanguine bloodline increases your caster level for any necromancy school spell by 1) can be a boon. Blasting spells tend to do a certain amount of damage based on your caster level, and while they have caps, slinging around the most damage dice you can as fast as you can is a pretty big help. It also doesn't hurt if you can apply metamagic feats to your spells, allowing them to surpass the normal amount of damage they'd do, maximizing the damage without rolling the dice, etc., etc. Furious Spell, in particular, can be helpful for those who intend to cast while under the effects of some kind of rage. And, of course, make sure you target a creature's weaknesses in order to get bonus damage out of your spells (a creature with a weakness to fire, for instance, takes 1.5 times the damage from fire spells).

However, it never hurts to add every point you can.

As an example, the evoker gets to add half their wizard level in bonus damage on spells that deal hit point damage. The trait Volatile Conduit allows you to boost a fire, cold, acid, or electricity spell by 1d4 damage as a free action once per day. There aren't as many of these abilities, as most combat feats specifically mention they cannot be used with touch attacks (or they must be used with a physical weapon), but even stacking on an addition d4 here or +2 there adds up over time.

  1. Hm. I'd actually be more interested in techniques to deal with creatures immune to fear in specific (for those intimidate-focused rogues out there) and mind-affecting in general (for all those enchanters, enchantment-focused sorcerers, and witches out there).

    Personal experience? Me? Naaaaaw, why would you think that? :)

  2. A level in Solar/Orc Crossblooded Sorcerer lets you add +1/die for damage and +2/die if that damage is fire. It also gives you Low-Light Vision and Darkvision.

    It pairs well with the Spell Sage Archetype, which also improves the Wizard's versatility. It's inefficient, but a 2-round CLW at the cost of two slots to get the healer off the ground really helps.
