Hi,
In the French version of the game Dr Drakken’s white skill says “réduit les vitesses d’attaque et de déplacement des ennemis charmés de 90%” which means it reduces attack and movement speed of charmed ennemies by 90%. Whereas in the correct one (meaning the English version of the game) it says " Decreasing […] of ennemies who are not Charmed by 90%". Basically the French description means the opposite of what it should be.
You could modify it by adding “[…] des ennemis non charmés […]” or “[…] des ennemis qui ne sont pas charmés […]”.
Hope this will help,
Best
