When doing the charge attack we should slow the players an amount of percentatge, for instance a 90% of the original velocity. This parameter should be exposed in the inspector. If we Slow for 100% the players should not be able to move.
To do this, a good idea might be doing a base Charged Attack class and make Lyriel and Death Charge attack inherit from it.
Stunning the enemies hit when the attack is fully charge should also go in the base class, with a boolean to enable or disable it ( as maybe we end up wanting it just for death instead of both characters)
