Stiffy Fear
Stiffy Fear is a Status Effect. It causes a bright purple skull to appear over enemy units' heads which makes them run away from the battle in fear. It is commonly used by skeleton characters, also known as Stiffies.
This is used by the Skeleton Warrior and interestingly, Necromancer-converted melee units.
As mentioned before, the Fear effect causes enemy units to run away in fear. During this effect, the unit cannot attack whatsoever and when the unit is possessed, it cannot be moved around. As such, the Fear effect often causes units to fall into hazards like water or the void, common in maps like Medieval 1, Spooky 1, Dynasty, etc. Due to the fear effect preventing attacks, Skeleton warriors and/or other units are able to swarm feared units easily without much resistance. The fear effect is not without faults, however. The fear effect does eventually run out and turns the unit back to normal. Additionally, bigger or boss units are much more resistant to the fear effect due to their size. The fear effect can also be detrimental against ranged units, depending on the map, as the fear effect can allow them to retreat back and get more shots on units, while the units have to walk back to them again.
