I made a version of this for myself that increases it from 70 to 110, which is enough of a change that instant killing most infantry becomes possible. 20000 is insane but I imagine that's intentional by the mod creator

it effects everything. also if you have enough stacked effects boosting charge bonus, you'll see an absolutely massive increase in the effectiveness of that unit

Question: How does this affect monsterous units and cavalry?

huh. Nice
I also found a charge reflector cap too. Could be fun to make stationary units benefit more from charge reflector
