As a person who went through the world war phase in his past life, Wil knows the best regarding the rules that weren't explicitly stated in the update details.
A few of them are:
There will be only personal system announcements for each player until the end of the war.
A player will have unlimited chances to revive and participate in the war but only the first enemy player who kills a fellow player will gain points according to the level.
When a player dies, he/she receives a non-removable debuff of 10% stat reduction which will stack upon every death until the ninth one. From then, the player will continue to maintain his 90% stat reduction until the end of the war.
During the world war, there is no safe zone. Players and NPCs can be killed at any place at any time.
