I think it would be a good idea if we could see our phobies getting physical damage after being attacked and when healed by healing phobies or health spas, the damage would slowly be removed until they are completely healed
For example, the damage that occurs on grave diggers statue after being attacked can be seen in the form of cracks but in this case it can apply to our phobies such as dents on robots and flesh tearing off of monster phobies.
