The protector gets scrolls based on his level of Justice. You gain Justice by killing reds. If you are working up Justice you need to wait 7 minutes between killing reds to gain.
By double clicking the Justice on the thing above your head on your paperdoll, you get a popup about who you offer protection to. You select someone doing the champ spawn. They can chose to be protected by you or not.
Everytime that person gets a white scroll (105) the protector also gets a white scroll (105). Everytime that person gets a pink scroll the protector gets a pink scroll. By having a protector you double ALL scrolls during a champ spawn.
Once the champ pops up the protector should NOT hit it. He should not do any type of damage to the champ or you will lose one scroll. The reason is that he can't protect himself.
You will get 6 scrolls divided amongst everyone who does enough damage to the champ and if the protector is a Knight of Justice then he will receive another 6 scrolls. They are all random, not duplicates.
Protectors can help out on a champ. Most guys have Discord on their protector and you can disco the champ making it hit for less and take more damage from the people attacking it. If you have necro you can also Corpse Skin and Evil Omen the champ, those curses don't do damage so you won't lose a scroll.
Make sure that you are either A) in some kind of form or B) have the spell Polymorph gump opened if you are going to Corpse Skin and Evil Omen Baracoon, as he will put you into rat form otherwise.
If your planning a template you have a lot of options. Right now I highly suggest:
120 Music
120 Discord
90 Provo
And get the bard mastery for Provoke. Party your group up and turn on that Provoke mastery. The buffs for party are crazy, the one I'm thinking of is the one that heals 7-16 points every 4 seconds to everyone in party.
You could consider hiding/stealth to get around easier... Magery to toss out EV's during the first levels of the spawn, Myst/Focus for the same thing with RC's. Something of that nature. If you want to use that Bard Mastery thing you need Focus and/or Med as they are very mana intensive.
