/*
Berserk is a modifier that grants vastly increased melee capability for a short period of time, easily allowing the
holder to do more than twice the damage they would normally do, as it both increases outgoing melee damage, and
reduces their attack delay. The screen will also turn deep red and the holder will get larger in size.
The modifier also gives some defenses, in that it gives additional max health (this can bite them in the ass later since
its not permanent), makes them move slightly faster, cancels disabling effects when it triggers, and reduces the power of
future disables by a very large amount. It also suppresses pain until it expires, however berserking while under massive pain
is likely to cause them to pass out when exhaustion hits.
Due to the intense rage felt by the holder, the focus needed to use ranged weapons is lost, making accuracy with them
massively reduced. The holder also feels less of a need to evade attacks and will be easier to hit.
Berserk can be extended by having another instance try to affect the holder while in the middle of a berserk.
After the modifier expires, a second modifier representing exhaustion is placed, which inflicts massive maluses and prevents
further berserks until it expires. This generally means that someone getting caught while exhausted will be much easier to fight,
as they will be much slower, attack slower, do less melee damage, be easier to hit, and disabling effects will affect them harder.
Berserking causes the holder to feel hungrier. If they are starving, this modifier cannot be applied. Diona cannot
be berserked, or those who are suffering from exhaustion. Non-Drone Synthetics that receive the berserk modifier will
instead get a version that has no benefits, but will not cost nutrition or cause exhaustion. Drones cannot receive berserk, as
they are emotionless automatrons.
Berserk is a somewhat rare modifier to obtain freely (and for good reason), however here are ways to see it in action;
- Red Slimes will berserk if they go rabid.
- Red slime core reactions will berserk slimes that can see the user in addition to making them go rabid.
- Red slime core reactions will berserk prometheans that can see the user.
- Bears will berserk when losing a fight.
- Changelings can evolve a 2 point ability to use a changeling-specific variant of Berserk, that replaces the text with a 'we' variant.
Recursive Enhancement allows the changeling to instead used an improved variant that features less exhaustion time and less nutrition drain.
- Xenoarch artifacts may have forced berserking as one of their effects. This is especially fun if an artifact that makes hostile mobs is nearby.
Will cause three brainloss in those affected due to the artifact meddling with their mind.
- A rare alien artifact might be found on the Surface, or obtained from Xenoarch, that causes berserking when it thinks
the wearer is in danger, however in addition to the usual drawbacks, each use causes three brainloss in the user, due to how
the artifact triggers the rage.
