Transcendent Pneumatic Alleviator (abbreviated as TPA) is a first order defensive spell which creates a magical impact shield around the caster.

The barrier functions as a force field that will completely absorb most forms of damage until it is destroyed.


This spell costs 45 GP to cast and takes up 25 units of mind space.


The following skills are used in the stages of this spell:


  • A handful of fine grey ash (consumed)
  • A shield (not consumed)

If the shield used is not a combat shield (i.e., one that cannot be used for blocking), the spell will be much weaker. The lightest proper shield currently in the game is a small leather shield.

Shield health and buffering

TPA buffering and shield health simulation

This shield has two aspects associated with it

  • The shield's total health, which is the total damage it can absorb.
  • The shield's buffer, which is a proportion of the current total health.

The shield's total health degrades:

  • At a steady rate as time passes.
  • Whenever the shield absorbs damage.

The buffer fills up whenever the shield takes damage and, if filled past capacity, causes the shield to break. While the shield is not taking damage, the buffer slowly empties. The colour of the shield is an indication of how full the buffer is. The shield colours are as follows, in increasing order of fullness of the buffer:

  • Colourless/invisible.
  • Dull red
  • Bright red
  • Wobbling orange.
  • Flickering yellow.
