This tutorial is for those already in possession of the 'keys' and have entered the 'arena'.
we usually use 4 or 5 Mystic spellweavers and having ventrilo, teamspeak, or such is very beneficial. Since Exodus has no slayer everyone having SDI suits/ spellbooks and naturally a 6 power 'circle' to begin.
once in the arena, run down the hill and stop before the 'square' in which Exodus spawns. cast paralyze fields at least 5 rows deep (east to west) and then 'arc emp' (arcane empowerment) and pre-cast a 'RC' (rising colossus) and (only 1 does this, the others have rc's waiting) run forward to spawn Exodus & 'drop' your rc at his feet. then haul ass back thru the waiting para fields

we learned that paralyze, mass sleep, sleep are all useless on Exodus but para fields work well. some tried to use energy fields but those not only block your rc but can block you as well and that can be disaster in the making.
ok, you got Exodus spawned, got fields & rc going, but his lifebar isn't turning red in a great hurry, what's wrong?? well, he's paragon 'coded' and the rc's are merely distractions to keep him off the real players / attackers. he likes to hit what hits him last so rc's are great to hit him quick right after you unleash an E-bolt, hailstorm, flamestrike, etc.. teamwork is KEY here. while 1 person fields, another makes sure at least 1 rc is up but try to keep 2-3 going at all times, and someone finds which element the Exodus has spawned weak against. some times it's cold, others it's energy, and so on. so you keep the para fields & rc's up, and everyone casts on him with whatever is hitting hardest. IMPORTANT: only use direct damage spells when fields & rc's are up. otherwise you'll end up having to run around, dragging Exodus w/ you.
Now, w/ the spellweavers having a 6 power focus, Word of Death (WoD) can hit for mega damage at 30% life. again, IMPORTANT note: this is where voice chat is super beneficial. you want to coordinate the attack so at least 2 players cast para fields while 2 or 3 are WoD'n him. if the wizards are setup extremely well and have 17-20 mana regen then the ones WoD'n cast 2-3x each and then switch to casting parafields and the fielders switch to WoD. rinse & repeat til he hits the ground

if all goes well, this scenario shouldn't take more than 15 minutes, 20 at most. the +5 stat scroll has been awarded to 1-4 players per run using this technique and as many as 6 players have confirmed drops in a single run. we've also noticed that the drops seem more plentiful the faster Exodus is killed. if the run takes more than 30 minutes, only 2-3 players get a drop usually.
i've seen sampires, throwers, tamers, archers, and bards all work this instance but for consistent, quick work of it, this is what we've found works best for everyone to get a drop, or at least a chance at one. if you've got a team where someone is willing to field for a thrower or archer, and doesn't care about a drop, sure, you can work it a little faster. this is not a method for speedy kills or hardest hits. this is for a team to all benefit equally.
as a side note: using this method, doing no more than 3-4 runs per day it took me 10 days to get all 14 of my toons (2 active accts) a +5 stat scroll & a box of the other drops.

if anyone has a different method, especially for 1-2 players working it, i'd love to hear it !!

PS: for the ever hungry for karma sampires, get a single set of keys, party w/ anyone else in game, and go to a shrine and use your set of keys. you'll get the +12,000 karma gain and not have to do Exodus. yes, necromancers can do it also for the -12,000 karma loss
