Blood of Chaos

Whether by accident or fate you have been exposed to the powers of elemental chaos.

Elemental Chaos

At 1st level, whenever you would cast a spell that would deal non-psychic damage, roll a D12. The damage type of the spell changes to the type rolled, shown by the chart below. At the DM's discretion, the spells effects may change with the damage type (cold may do less damage but slow the target instead).

1. acid
2. bludeoning
3. cold
4. fire 
5. force
6. lightning
7. necrotic
8. piercing
9. poison
10. radiant
11. slashing
12. thunder

Chaotic Resistance

At 1st level, whenever you would take non-psychic damage from a spell, roll a D12. If the rolled type(determined by the chart up above)is of the same type as the spells type, you take no damage of that type from that spell, but if the rolled type is opposite(fire-cold  radiant-necrotic),you take twice as much damage of that type from that spell. Otherwise damage is dealt as usual.

Semblance of Control

At 6th level, whenever you roll for Elemental Chaos or Chaotic resistance you may reroll the D12  and take whichever result you choose. 

Also as a reaction, you may force another creature to roll a D12 when it casts a spell(as if it had Elemental Chaos) or when it takes non-pyschic damage from a spell(as if it had Chaotic Resistance).

Chaotic Summoning

At 14th level, as an action roll a D12 to choose a creature type(shown by the chart below) to summon then invest a number of sorcerer points equal to half the challenge rating or lower of the creature you want to summon within the rolled creature type. The creature is summoned within 60 feet of you and is played by the DM. The DM decides wether the creature is hostile to you or not.

1. fiends
2. undead
3. celestial
4. beast
5. dragon
6. demon
7. fey
8. ooze
9. plants
10. giants
11. monstrosity
12. reroll the D12

Chaotic Mastery

At 18th level, whenever you would roll a D12 for  Elemental Chaos, Chaotic Resistance, or Chaotic Summoning, you may instead choose a damage type(Elemental chaos,Chaotic Resistance) or creature type(Chaotic Summoning).
