With the level of immersion and freedom that was allowed by Morpheus Online, utilizing the concepts of physics was also quite viable.
Of course while this might not work with all the enemies, in the case of several low leveled ones, it still worked. Arthur had used the very same thing and relied on the thermal expansion and contraction to break the scales of the Grogal.
The repeated heating of the scales with the Draconids breath was perfect for it and was also why Arthur had gotten Brambles to only target the Grogal's back. The final addition of Frost Touch brought down the temperature suddenly which caused the scales to shatter apart.
With that, the skill of the field boss was disabled permanently allowing Arthur to finally deal proper damage to it.
"GURAAAAAAAAA~!" Of course the Grogal was not pleased by it and was actually in decent pain.
But that was only the start of it all as Arthur attacked right away.
