Truth dosent do nearly the damage of gally, gally does almost twice as much, the only hope Is you can launch 3 truth rockets, if you want to.compare raw dps you should be going with dragon's breath as its the only thing in game that's even close and is as.good as it better in some.situations (just ir yut haha) Also the biggest and most overlooked reason xur probably won't sell it is because if he did half the comunity would rage quit, while alot would get it and stop playing nearly as much because it's the one thing their chasing.
