Summary

Ambient Tempests are metamagic defined casters. Their spellshaping actually allows you to sculpt the spell to omit allies and hit only the enemies, not as cleanly as Spellwarp Sniper but able to sculpt it in a variety of ways instead of just shape. This class flourishes with high numbers of lower level spell slots. Their niche is to alter and change their spells in some fashion up to changing what spells they even know.

Class Features

All of the following are class features of the Ambient Tempest.

Weapon and Armor Proficiency: A Ambient Tempest is proficient with whatever they were already proficient with.

Spells per Day/Spells Known: From 2nd level on, when a new ambient tempest level is gained, the character gains new spells per day as if he had also gained a level in whatever spontaneous casting class he belonged to before he added the prestige class. He does not, however, gain any other benefit a character of that class would have gained (turning or rebuking level for mystics with the Sun or Necromancy domains, bard or assassin abilities, etc). This essentially means that he adds the level of ambient tempest to the level of whatever other spontaneous spellcasting class the character has; then he determines spells per day and caster level accordingly. If a character had more than one spontaneous spellcasting class before he became an ambient tempest, he must decide to which class he adds each level of ambient tempest for the purpose of determining spells per day.

Shifting KnowledgeEx: Once per week, the ambient tempest can meditate for an hour and learn a single new spell in place of one he already knows. This ability works just like the standard sorcerer and mystic ability to swap a spell, save for the frequency with which it can be used. Thus, the spell to be swapped must be at least two levels lower than the highest-level spell he can cast.

Ambient Secret: The ambient tempest begins to better understand the natural ebb and flow of the so-called “wild” magic, and he is able to fine-tune his use of ambient magic in a manner that gives him greater control over the effects of his spells. An ambient tempest is able to choose from a variety of ambient secrets. Unless otherwise noted, no ambient secret may be selected more than once.

Improved Metamagic With this ability, the ambient tempest can use a metamagic feat on a spell without needing to take a full-round action.

Improved Shifting An ambient tempest is no longer subject to level limitations on the spell that he can shift in and out of his known spells.

Metamagic Feat An ambient tempest can choose to learn a new metamagic feat in place of another ambient secret. This ability may be taken more than once.

Shifting Knowledge Each time the ambient tempest takes this ability, he adds one to the number of spells he can shift each week. He can still only ever use the shifting knowledge ability once per week, regardless of whether or not he has replaced his full allotment of spells. For example, an ambient tempest with the ability to shift three spells a week can opt to only shift one spell from his repertoire, but he cannot choose to shift the other two until a week has passed. The ambient tempest must spend one hour of meditation for each spell to be replaced. This ability can be taken more than once.

SpellshapingEx: The ambient tempest can alter a spell with certain metamagic feats in a manner that actually reduces its effect (and its level as well). This ability can affect the Enlarge, Extend, and Widen Spell metamagic feats, causing them to halve whatever aspect of the spell they normally affect instead of doubling it. Regardless of which feat is affected, a spell under the effect of a spellshaped feat uses up a spell slot one level lower than the spell’s actual level. An ambient tempest can only use one spellshaped metamagic feat on any given casting of a spell.
