I've been trying to beat Estark Extreme for days now in DQ Heroes 2, but cant get anywhere close. I'm looking for some co-op help for the boss fight. and yes I am level 99. I want to get the platinum trophy, however theirs a trophy that requires all weapons and you can get Estark's weapons if you beat his Extreme fight in under 8 minutes. If anyone out there could help I would gladly appreciate it
