The strength of obsidian on United Factions

How strong is obsidian? is it really true it can withstand the blasts of a TNT block impact? Yes it is indeed! But.. nothing is unbreakable ;) The endurance of obsidian is set to a certain amount of impacts.

Obsidian will defend your base against a raid, however it will still be possible for a raiding faction to destroy your obsidian defences. 

The minimum impacts obsidian can take is set to 10 TNT blasts before the obsidian finally breaks into pieces.
