+
+- `NO_EXPLOSION_VFX` - spell has no visual explosion
+
+- `LOUD` - spell makes extra noise at target
+

+  category
+
+- `WONDER` - instead of casting each of the extra_spells, it picks N of them and casts them (where N
+  is std::min( damage(), number_of_spells ))
+
+- `PAIN_NORESIST` - pain altering spells can't be resisted (like with the deadened trait)
+
+- `NO_FAIL` - this spell cannot fail when you cast it
