Hephaestus' child: God of fire and weaponry stands out
Dances for triumph but fails
A bisque fulmination: 1 odds allowed an inferior player & 2 unglazed china that is not to be glazed but is hard-fired and vitreous
1 to send forth censures or invectives
Joins in its broken pride
In futility lavished: uselessness
By a redoubt of marksmen: protective barrier
Solace through backlog: 1 a large log at the back of a hearth fire & 2 an accumulation of tasks unperformed or materials not processed
Summarily applied
I'm thinking it's a weapon with a flame ability if it isn't Ifirit. My guess is Flame Sword.
