Both houses can propose laws, declare war, override the president veto with 2/3 vote, and can propose amendments to the constitution with 2/3 veto.
Public Events are one way that players can try and get an Exotic Engram to drop. Itâs a small chance at best, but since Public Events are so fast and easy to find now, theyâre not a terrible option.
There's no exotic engram drops. You can buy them from Xur. Never personally seen one drop in the Crucible. That's engrams though, plenty of weapons to be had lol
