# Monsters

Monsters have two properties: level and rank. The notation I use for
these are "`lvNNNrN`" i.e. "`lv150r5 Archvile`."

Upon spawn, both of these are assigned with a random formula based on
the current skill level and difficulty base setting. Leveling up will
give a monster more health if their level is above 5, and more random
damage type resistances if their rank is more than 1 star. Two
resistance points are granted every 10 levels.

A monster's rank scales some factors for them, including health gained
per level and base resistances.

Monsters can gain levels by damaging other things, including the
player and other monsters. The maximum rank is 5 and the maximum base
level is 150. Monsters may level up past 150, but cannot level up in
rank.

Monsters with a rank under 5 stars will have a blue colored barrier,
which becomes visible at level 20 and increasingly visible with higher
level and rank. Monsters with a rank of 5 stars will have a rainbow
barrier, or "Heptaura."
