So, I've just about finished a Magus build I'm working on but I'm trying to give it a theme, but there don't seem to be enough spells to work with it. I'm going to be using the Blackblade with the color that the sentient blade looks like it is made of deep blue ice, so I'm trying to find a way to fit the cold / ice / frost theme into the spells known and used but there don't seem to be many on the magus spell list.

Is there a way to convert the element of other spells like say.... Burning Hands, Acid Arrow, or Shocking Grasp are usable with cold instead of their respective elements?

I'm pretty sure there's a Feat which can be taken multiple times that allows you to shift elements of a spell to any one other.

Ah yes, Elemental Spell.

Bumps the spell up one level though, so a level 1 becomes 2, 2 becomes 3, etc.

Also, have you thought about being a Suli that's tied to Cold?

Not familiar with a Suli...?

It's one of the Uncommon races. They're like half human/half <Insert Djinn Here>

http://www.d20pfsrd.com/races/other-races/uncommon-races/arg-suli

If you pick the alternate racial trait "Energy Strike" it replaces your ability to pick your elemental damage for Elemental Assault but lets you deal it with one specific element plus other abilities.

This is the Cold option:

"Icewalk (cold): The suli can walk on water-based liquids as if using water walk, except instead of hovering above the surface, she creates a temporary layer of ice that supports her and immediately melts once she moves away from it. This ice is not slippery to the suli and does not affect her balance or speed, though other ice affects her normally. Other creatures cannot travel on this ice, but the suli may carry a creature while moving."

-2 Int kinda hurts though, but it's definitely the most flavorful option I can think of.

Elemental Spell is one.

Alternatively, a level dip into Sorcerer, and there's some bloodlines that let you change the energy type of a spell into cold. One of which is Elemental, and another is the Marid bloodline.

Suli are a race of humanoids with Genie blood in their ancestry.

That Suli thing is coooool.

A dip into sorc could be useful with broad study?

A level dip into wizard can get the Evocation Admixture subschool which allows on-the-fly elemental damage type changing 3+ int times per day.

It seems that there are at least one or two spells for every level other than 3rd that are perfect for this theme. Ray of frost, chill touch (not cold, but come on, it's called chill touch!), frostbite, elemental touch, frigid touch, dragon's breath, ice storm, wall of ice, cone of cold, freezing sphere. If you're still hurting for other options, the samsarans can get other spells added to their spell list via the mystic past life alt. racial trait.

Not really sure. I haven't checked the sorcerer spell list for a long time to see if there is anything good for a 1st level spell.

Well, I am a fan of the defiler build, so I particularly love the Rimed Spellmetamagic feat. It makes ice spells entangle the target for a number of rounds equal to the spell's original level.

It works particularly well with two magus spells, Frostbite and Frigid touch. Both are touch spells that do damage and add a another status condition (fatigued and staggered respectively) without a save. Combined with Rimed spell, both puts a lot of suck on opponents. Frostbite can be used 1/per level each casting (but only does 1d6 nonleathal) and Frigid touch does 4d6 damage.

There are also a pair of traits, Magical Lineage and Wayang Spellhunter, that allows you to add Rimed spell without increasing their spell level. Oh course, that depends on whether your GM would let you add the latter...

I really love the idea of a Magus with Magical Lineage(Frigid Touch)and Rhimed Spell.

• 4d6 damage
  
• may take a single move action or standard action each round (but not both, nor can he take full-round actions)
  
• half speed
  
• cannot run
  
• cannot charge
  
• –2 penalty on attack rolls
  
• –4 penalty to Dexterity
  
• DC 17 concentration check to cast a spell

You could play a blade bound magus that ferries souls to their proper place while fighting and hunting daemons ;)

Even without broad study a sorc dip can be worth it. Make it crossblooded and you not only get to change spells to cold damage on the fly but another benefit in addition to that.
And one can never have anough cantrips, even if you can't combine them with spell combat or spellstrike.
If you chose to be marid/White dragon bloodline for example you get to change spells to cold and get +1 damage/die rolled when casting frost spells.
The special boon is that you still CAN cast the spells normally.

By being crossblooded you learn 1 fewer spell per spell level meaning you only know 3 cantrips and 1 first level spell. But the benefits are worth it in my book.

But to pull this off you need at least Cha 11.

And while you're at it, along with that crossblooded white dragon/marid dip, tack on the seeker bloodline to get trapfinding as a rogue, +1 to perc/dis device for traps, and disable device as a class skill.

Gives up the Eschew Materials feat... fair trade.

If a player in my game wanted to do it, I'd totally allow them to use the Staff Magus archetype and re-theme all of their staves as scythes!

There's the standard Blackblade strike ability which lets you turn the blades's weapon damage into an element of your choice.

Elemental Spell.

I was going to make a Magus that was basically a Fire Bender with this.

Human Magus 1

Trait: Magical Lineage (Shocking Grasp)

1: Imp Unarmed, Elemental Spell

Now Shocking Grasp can become Flaming Grasp or Half shocking half flaming.

First Level Spells: Flaming Grasp, Burning Hands, Flare Burst,

Second Level: Burning Gaze, Elemental Touch, Fire Breath, Flaming Sphere, Scorching Ray, Pyrotechnics

Third Level: Elemental Aura, Fireball, Flame Arrow

Etc etc.

Fire Benders!

This is more of a Water Bender though...

Honestly, Elemental Spell is your best bet.

Suli are a race of humanoids with Genie blood in their ancestry.

** spoiler omitted **

I didn't, I'm not even sure what /tg/ is. lol

It's probably better that you don't. ;)

As far as your ice-based Magus, I think the others have given you some good ideas to work with.

If you have access to the Class Feature that grants you access to Wizard spells as Magus spells you can access some more Cold based spells.

I have had NO trouble finding an ice cold theme with magi.

I couldn't find a class feature for the Magus that lets them access the Wizards spell lest, unless you are talking about the ability you can take that will let you use your Magus abilities with spells you have in other classes you have levels in?

That's a pretty awesome Arcana but I want to try to stay to a single class. So I think the metamagic one to change the spell is my best bet at this time. Though, I plan to talk to my gm about changing the color of some of the spells to ice to fit the character theme.

no there is an arcana that gives access to limited amounts of wizard spells too

no there is an arcana that gives access to limited amounts of wizard spells too

Oh! I think I see what you are talking about. At level 19 they get greater spell access to allow them to cast wizard spells. A long, long way for me to go! lol

He meant Spell Blending, the arcana.

There's more than one way.

Oooo I see, I completely missed that one! So many options, so terrible reading comprehension!

Greater Spell Access.

Spell Blending.

Both give access to additional spells.

Samsaran magus with the Mystic Past Life alternate racial ability is also an option.
