It should not be framerate dependent, but I did want it to shoot out a large number of flames so that it would look more like fire breath since I wasn't able to learn the particle system enough to do that, I should probably reduce the damage per bolt so that it won't kill you outright if you get hit by one or two. I have some ideas on how to tweak the tank to make it feel better and not get one shot at higher health levels as well. Right now it works by reducing the damage by a large percentage, but I might try out making it take a fixed amount of damage instead. Thanks for the feedback!
