Hello. I'm thinking of adding the berserker unit attribute to EB for BI, but I don't know enough about it yet to make a good decision. Here is the description for it:
Berserker units can go berserk (BI Only)
And it replaces one of the other stat_mental "discipline" attributes (low, normal, disciplined, impetuous).

What does it do *exactly*? It is like "run amok" for elephants? Do they automatically fight to the death instead of fleeing? Any state bonuses I should be aware of? Does it displace special unit abilities like shield_wall or warcry?

It could be an interesting addition for units like the gaesatae and other elite barbarian units.
