Lead the forces of light to victory!
Henzell says...
  1. Assuming you aren't monstrous, you get five facets, each consisting of three mutations (which usually just stack together). You will get one scales-type facet, one body-slot facet, two tier 2 facets, and one tier 3 facet.
  2. The {scales}-type facets are icy blue, iridescent, molten, rough black, rugged brown, slimy green, thin metallic, or yellow scales, or alternatively thin skeletal structure, large bone plates, sanguine armour, sturdy frame, or repulsion field. Body-slot facets: claws, horns, antennae, hooves, talons.
  3. Tier 2 facets: powered by death, powered by pain, demonic guardian, spiny, rot (rRot, foul stench), fire (rF+, flame cloud immunity, ignite blood), ice (rC+, freezing cloud immunity, icemail), magic shield.
  4. Tier 3 facets: robust (+30% HP), damnation ({demonic willpower}, {rtorment}, hurl {damnation}), negative energy (rN+/rTorment/black mark), {augmentation} (+slay/spellpower scaling with HP), ice (rC+, freezing cloud immunity, passive freeze), fire (rF+, flame cloud immunity, hellfire). Ice/fire facets are incompatible, as are foul stench/ignite blood.
  5. If you are monstrous (1 in 10 chance), then you get 3 body-slot facets but you don't get scales. You still get 2 tier 2 facets and 1 tier 3 facet, for 6 facets total. Your first body slot mutation will come with the message, "You feel monstrous as your demonic heritage exerts itself."
  6. Which XL each mutation is placed at is random, but different mutations try to place themselves at different times. For example, you should usually get your body slot mutation(s) in the first 2/3 of your mutations, and you usually only start your tier 3 facet in the second half.
