Helm of inmost light or eternal warrior. First has light coming out and allows you to aim fist and increases the jump off it (?). Eternal warrior is my avatar and makes you harder to kill as you use fist

i'm pretty sure the first one is the one i was talking about, i'm a Hunter main so i don't know all the Titan exotics. :I thanks for telling me the name though, i just remember it as "that helmet with a crack in it that i usually throw myself off the map with" i remember wanting to use the second one, but it was year 2 and it didn't get a light update so i didn't want to use it, but from the text it looked like it was a great exotic though.
