Get Coyle & Co. to (or near) the library door

 * Coyle Lovell, the NPC you love to hate. Keep him back behind the group for safety.
 * If you have a party member who can stay far in back (perhaps a healer, ranged, or caster), have that party member talk to Coyle & Co. and keep them well away from the fighting. Certain monsters will respawn in some areas and will roam the passages; so don't just leave Coyle at the start entrance for several minutes.
 * The first passage south only has a few fire mephits; the second one takes you past WF clerics, a rust monster, and air mephits. Your choice.
 * Once in the final hallway, hold Coyle back while you disable the two blade traps (before the blocked intersection). Then, just before the library door, same with the sonic trap. Don't advance Coyle yet...
 * In that final hallway to the library (with the traps), there are some bookshelves to the south. Do *not* have Coyle and company follow you in there - they are not smart enough to get out (although it is possible to slowly push them out).
 * The library door is locked by 2 signal crystals, requiring you to flip 2 levers, 1 each found north and south. When Coyle gets near the library door, an ambush will spring - read below...

The doors north and south

 * Once Coyle is near the locked library, the two blocked doors (leading north and south) will break open, with an earth elemental coming through each. Kill both earth elementals, or Coyle will bravely die fighting the one you skipped.
 * If you can lead Coyle & Co. up to the door itself, he will stay there, and be close to where the end-fight spawns when the second lever is pulled (far away). If, otoh, you stop once the side doors burst open, nearer that intersection, you can tell him to stop there, well away from the end fight when the final door is open. The NPC's will be safe there from re-spawns.
 * North:
 * The second shrine in the north wing is opened by a lever up the stairs in the large room.
 * The alcove behind the secret door with the northern rune lever is empty.
 * South:
 * The first lever has a Str check (17-18) to reach the chest.
 * South of the STR lever is another lever which opens the way forward. This is protected by a single row of spike traps - easily timed, and also disabled by the lever.
 * mischief        = 61
 * vandal          = 80
 * ransack         = 98
 * neutralization  = 2
 * bonus_xp_notes  = To reach the kill bonuses it is required to kill respawns.  The Glass Spider and Rust Monster before the first trap respawn every 3 minutes, as well as the two Flesh Renders by the northern lever that controls a crystal to open the Library door.
