"They can use decay to heal too." Remey didn't say this out of surprise, it was just a general fact. She was just making sure that the idea itself was said out loud since it was something that anyone else would cite as very odd.
There was also the fact that Alice and Su would be the ones who were most focussed on the forms of healing that the obsidian slime race were capable of. Especially since there were many back in Genesis focusing on the fact that there were either forms of elemental healing other than light or life mana based healing.
"They are the ones that use the decaying dark mana in just about everything. They seem to be a race entirely focused on the magical aspect of dark mana and how it works in nature. I have a feeling they can travel the world without much issue." With the way that Gil was taking this, he felt that the obsidian slime race could easily visit Genesis without losing too much or being too much at risk.
