We were all proven wrong by ourselves regarding the Obsidian weapons in the end. They were different because they were easier to break block with! Obsidian Edge is considered inferior to Acheron but I'm thinking that it has an edge (hah) over its non-status counterpart and that's the charge's improved block breaking mechanics vs enemies that have shields such as Mecha Knights, Gremlin Mortars, and Gremlin Thwackers.
Sadly, this thought only struck me today as I was running O:CH and I've done no proper observation, analysis, or recording. Any thoughts or facts on the matter?
Sorry, but I don't understand. Is this a joke that I'm not getting? Does "block" mean enemy shield? How does Obsidian Edge help? Thanks.
