The veil for Ceizak delve is located on a rock midway on the path at H-8. The closest waypoint is biovac #1 then run north then west.

5/5NM + Boss Ceizak Strategy:
DDx3 (at least 1 needs to be a Requi DD or mura SAM) BRD COR WHM
RNGx3 DRG BRD COR
SCHx3 RDM GEOx2

Corsairs and BRDs (if both not 4song) swap FULLTIME (if 4song BRDs then only swap at boss). CORs and BRDs each pick one DD to haste, since RNGs don't need. RNGs will need to end up with 4x Minuet and Chaos/Samurai/Coursers/Rogue rolls for NMs and will need Chaos/Samurai/Hunter's/Courser's for the Boss. DDs will want at minimum March x2 Minuetx2 and Chaos/Samurai/Fighter/Rogue for the NMs, DDs will want at minimum Marchx2 Madrigalx2 Minuetx2 and Chaos/Samurai/Fighter/Rogue rolls for Bee.

Butterfly - kill normally, do light or dark at 49% and 24% hp to break the DT
Chapuli - do not silence, only WS while it casts, can WS anytime after it reaches 20%
Scorpion - keep it dia'd, RDM chainspell stuns at 40%, should use Embrava at this time
Gnat - both GEO need to use 2x debuffs, RDM needs to keep poison/addle on, BRDs need to keep thren/requiem, everyone pwns if the enfeebs stay on, should embrava at about 50%, no WSes with additional effects, after 65% can use murasamemarus + requiscats
Wamoura BRD debuffs only, power through to kill, 20 exuviations until DT gone, use murasamemarus and requiscats from 100% until dmg normalizes, no WSes with additional effects
Bee RNGs try to hold back until 65%, treat first 75% like a melee zerg, use embrava at 25%, RNGs start steady DD after 65% and do heavy dmg after 35% and use coronach only please, mursamemarus + requiscats after 25%
