How do you increase the passive heal rate of hero/explorers?

I’ve been trying to mod Kichiro to increase his passive health regen but I can’t for the life of me figure out where to do that, I looked through protoy and ypspckichiro.tactics files and I couldn’t find it.
Also is it possible to make the healing work even if the explorer isn’t idle?
Would appreciate any tips

Edit: nevermind, it was as simple as adding a “unitregen” line

The regeneration is set in the civs.xml file ^^
