They're not healing , their max HP is being reduced with each hit GAS gives them without protection (is in the kit)
It may appear as healing, but their max health is getting lower and lower each time,
Let me put some maths on it
Let's say GAS hits the 10,000 HP enemy, and he does 2,100 dmg, GAS unique, if I'm not wrong, reduces 20% Max health, so, the New enemy Max health will be 8000 HP, with that hit, it would be 7,900 HP left on the enemy, but due to his max health now being 8,000, he is closer to the max than he would be if the enemy still had 10,000
That's why IT appears like it is healing, but it's not
Hope I explained myself
