Doomsday Engine

This isn't exactly a bug in JHexen; it's more of a bug in
the original Hexen source code that never got fixed.

Every single time a Heresiarch (the sorceror boss with
the 3 spinning mana cubes above his head) 'wakes up'
(i.e. from being attacked by another monster or seeing
you), it spawns a set of mana cubes above his head.
The problem is that if they wake up multiple times (by
getting distracted by another monster and then seeing
you again), they spawn ANOTHER set of mana cubes
and reduces their spell casting time (1/2, 1/3, 1/4, etc.).
This can make them practically impossible to kill
(especially on skill 5), since they re-cast their
invulnerability spell so quickly (usually it takes about 3
seconds, but with this bug it can quickly be reduced to
just over half a second).
