Damage Types

Resistance & Susceptibility Descriptors:
insignificantly     partially       quite               outstandingly
faintly             kind of         substantially       extraordinarily
hardly              somewhat        very                completely
barely              moderately      exceedingly
scarcely            reasonably      exceptionally
slightly            rather          extremely

The following damage types are relatively common in our realm:
air             chopping        fire            pure divine
biological      cold            mental          slicing
blasting        cursed          piercing        water
blunt           earth           poison          whipping
caustic         electric        pure arcane

These damage types may occasionally be encountered, but they are more rare:
leeching        pressure        stasis
mind control    sonic

These types are hardly (if ever) used.  At some point in the future some
of them may be repurposed for some new type of damage.
antimagic       natural         portal
falling         polymorph       radiant

Damage dealt

Some races will also deal damage of some of these types, based on what their resistances are. Right now these appear to be only evolutionary races: firedrakes, imps, and elemental giants. This will show up in 'score'.

For a low hero firedrake:
Attacks from your dominant hand are augmented with fire damage.
Attacks from your offhand are augmented with fire damage.

For a dust imp:
Attacks from your dominant hand are augmented with earth damage.
Attacks from your offhand are augmented with earth damage.
