You can be revived by surviving gang members and return after the storm. However, if all of your members die before a storm, then that is the end of the beef/war - If you are water dumped or have decent RP behind killing someone, i.e water dumping, throwing someone into a smelter, meat grinder etc, you are not allowed to remember or be reminded and you are now out of the beef/war.
No loopholing this rule:
Nobody outside of your gang is allowed to revive you, and you cannot fly out if you are the last person alive.
If you fly out during the war, you are classed as dead—no excuses.
Additional Rule: Once you are killed, change out of your gang fit and put on normal clothes.
If you remain in your gang fit and get killed again, don’t complain—it’s your fault.
