We will take 36 players but can enter a zone with 30 for a successful run. 
Things to know about Einherjar:

1. Pulling a mob will not link all other mobs of the same type. Standard link rules apply npw

2. Certain mob will spawn depending on which mobs you have pulled that will either
    strengthen the other mobs if left to despawn or weaken the rest of the mobs if      killed.

3.  Reraise items, echo drops and Poison pots are a must!  As well as icarus wings for DD

4.  Fighting can not start until everyone is in the chamber or any player that has not      entered will be locked out.  (just like limbus)

    5.  Mobs in the room come in sets of 6 and 12, so at the start it is better to pull     the groups of 6 first.  This will not hold true for undead mobs because they will     aggro to low hp.
