Was able to partially do it with the help of ChatGPT. The the settings i produced is like whats on conf. The hide_woe_damage. The hide_woe_damage just masked the damage into "1".
I cant find the GVG settings where you can actually hide the damage sprites.
BTW this is the chatgpt session:
atcommand.cpp
clif.cpp
and finally pc.hpp
Needs little cleanup but it behaves like hide_woe_damage. (only display 1 damage)
