description: >
  Test game for trigger timing and optional triggers. One event `damage` with an impact (hp -2).
  Each trigger appends a letter to `log`, so the order is visible: f = mandatory 'when',
  w = optional 'when' (heals 1), X = optional 'instead', Y = mandatory 'instead' (only with armour),
  I = the impact itself, a = 'after', d = trigger on the content item Thorn (active only when
  equipped).
