Perception L Guide / Traps Location within BA
Courtesy of E'ric Tia : Perception L GuideInside BA there are a number of traps which can vary in lethality from a Massive Explosion which will instantly kill anyone without invulnerability to a Strong Dot with a 10-minute vulnerability up attached.
Perception L is a DPS exclusive action and is highly recommended to have one or two DPS in charge of percepting for the run.
Disclaimer
This is considered to be an intermediate topic for BA and you should not feel pressured to percept if it is your first time in BA.
Logos Action Configuration
Pair this with a DPS Wisdom like Wisdom of the Fiendhunter or Wisdom of the Elder.
Optional: when you first start percepting, it is okay to pair this with Wisdom of the Platebearer in case you accidentally pull additional mobs.
This will be your setup for the rest of the run.
Using Perception L, These are the possible messages that you can receive.
Nothing in range (36 yalms) - "Not Close"/"Far"
Within 36 yalms, but not within 15 yalms - "Closer"/"Near"
You have found a trap!
Post Art / Owain Stairs
1 trap here, in 3 possible locations.
The safe spot to percept in a little bit past the thick line at the top of the stairs. This spot will hit all 3 locations.
Yellow circles = other possible locations
Open Area where ART / OWAIN Team meets
There are 4 bleed traps here.
They are always in a square.
This square is usually off-center relative to the room.
The middle column that extends up the hallway to Raiden never has traps on it.
The traps can be quite close to the doors you enter from.
Room after Raiden
1 bleed trap in here
The Raid/Tanks will want to know if it's close to the top of the stairs [“you sense a concealed trap nearby”] so they know how careful to be when pulling mobs.
Yell chat is good for communicating with the raid.
You can move in and carefully move around places you’ve cleared with percept that are out of mobs’ aggro range. Sleeping enemies won’t aggro until they wake up.
Yellow circles = most common trap locations
Before the Treasure Coffer
1 explosion trap, 3 possible locations.
The spot to safely percept is just past the first square or thin border after the big double line, see red rectangle in the image to the right.
Elemental Rooms
In these rooms we’re looking for traps, but one of them also has The Portal.
The portal counts as a trap for the pop ups, i.e. if you’ve found all the traps in the room, and percept still pops up “you sense a concealed trap nearby” the portal is in that room.
Remember to check for portal after you find the traps.
Percept in the middle-back of the room after you’ve found all traps. If it still says “concealed trap nearby” the portal is in that room and you should keep percepting to find it.
The first two rooms, earth and fire, have 0 traps, portal can spawn in the back middle of the room.
The middle two, wind and lightning, have 1 explosion trap each. Portal can spawn in the back corners of the room.
The last two rooms, ice and water, have 2 explosion traps each. Portal can spawn in the back corners of the room.
The Raid will also want to know which room has the Treasure Coffer in it, which is usually the first room cleared because of Loot.
You can check each room for the chest as you’re progressing along the hallway, although Water and Fire are tricky to see from the hallway due to being behind stuff.
Be careful with Wind and Lightning rooms, it's easy to aggro them from the doorway.
Blue circle = Possible portal spawn - Remember to check for it after finding the traps!
Water chest & Fire chest can be hard to see from the doorway, look for the glow around the pillars
Post Portal Trash Room
1 bleed trap in here.
Again, we percept at the bottom of the stairs and alert the raid if it’s close, then move around percepting until it’s found.
For more information, see the room after Raiden, they’re functionally identical.
Yellow circles = most common places
Support Fate Hallway
Every room has 1 trap in it, it’ll be next to the blue circle used to spawn the Support FATE.
You can percept each room in 2 percepts every time:
1: Walk up to the 3rd or 4th cross (left), or the dividing line for fire/earth (right) and percept.
If this doesn't find the trap:
2: Walk up to the edge of the blue and percept again. This will hit every remaining possible spot for the trap.
Yellow circles =
4 possible spawn locations
