Balance Help : Mythic Cone of Cold

[Bob Dobbs 875]

I have an ice-themed friend in my party who wants to use water and cold magic as a theme. We're hoping to come up with a Mythic Cone of Cold spell.

I tried to pattern it off of mythic fireball, but that spell has unique burning mechanics that fit Cone of Cold poorly.

So, I was wondering if you guys have any suggestions? We've been playing Pathfinder only two weeks and we're not really tuning savvy yet.

Hey, also, if you feel generous, do a Mythic Frigid Touch!... or any other cold/water themed spells you can imagine. Thanks for the help!

For Mythic Cone of Cold, I'd just do the d10 die damage upgrade + Rime Spell built in (entangled for 1 round per spell level), or possibly the Rime-Blooded Bloodline Arcana, but upshifted to 1 round per spell level.

Bloodline Arcana: Whenever you cast a spell with the cold descriptor, you may select one target of the spell to be slowed (as the spell) for 1 round. A Fortitude save (DC 10 + the level of cold spell + your Charisma modifier) negates the effect.

I pretty much agree that some sort of movement restricting effect is appropriate, in addition to the dice going up to d10s.

Perhaps...

1d10 cold damage per caster level (maximum of 15d10) and on a failed save targets are entangled and unable to move unless they make a Strength or Escape Artist check with a DC equal to the spell's save DC. Fire damage can melt the icy bonds, which have 1hp per caster level, but the trapped creature takes damage as well.
