Entropist

Enchantment Tale
Entropists are often heralded by the frigid winds of the north blowing through the countryside, bringing a freezing chill at the most unnatural of times. These wizards have harnessed the magic of negative entropy, a field studied extensively by the Sh’thani spiretechnicians of old. During the Age of Spires, the magic of forced order from chaos was harnessed to empower many spiretech devices. The ad-hoc usage of this magic (without the channel of spiretech) often manifests as “ice” magic. Entropists are masters of this art, producing chill and frost at will, and shaping the chaos of natural moisture and temperature into frozen forms of their desire.
Icicles • Signature Talent
You start each encounter with a number of icicles equal to your Magic + mastery. You may spend Icicles to temporarily increase the entropy of a device when taking the Operate action (limit of one icicle per action). (Icicles may also be spent on other actions in this tale.)
Frozen Armor • Tier 1 Talent • Action
Spend any amount of icicles to gain that much armor until the start of your next turn (if in danger, or for 1 minute otherwise).
Chilling Strike • Tier 1 Talent
Anytime you successfully make an Attack (Weapon) action, you may spend one of your icicles; if you do, the target of the attack is slowed in addition to any other effects.
Ice Lance • Tier 2 Talent • Action
Make a Magic vs Steel check against a nearby character; if successful, deal d4 + Magic damage to that character. In addition, if successful, you may spend one of your icicles - if you do, that character is also frozen.
Critical: Gain one icicle (you cannot go above your normal maximum).
Frostbite • Tier 2 Talent • Action
For the next 10 minutes, your touch or step instantly freezes any water it touches. Holding your touch or step to a location will cause the frozen patch to grow slowly over time.
Ice Palace • Tier 3 Talent • Action
Spend any number of icicles - manifest a building or structure of pure ice whose total size is 10 times the number of icicles, cubed. The construction can be any intricacy you want, and can contain furniture or other smaller structures also made of ice. The temperature inside the structure is moderate. The structure will last for 1 + mastery days, after which it will rapidly melt and evaporate, leaving no trace behind.
Frozen Heart • Tier 3 Talent
You are completely comfortable in any cold condition, and you can, as a free action, reduce the temperature of the area around you (a radius of 10 times mastery feet) to the freezing point. The chill will dissipate within minutes after you release it, or you leave the area.
Tarr’ko • Tarr'ko Talent
You gain an innate tarr’ko card - Channel, the Uncontrolled Arcane.
Notes: Innate tarr’ko cards cannot be lost, stolen, or exchanged; they are gibberish to anyone else who looks at them.
