Turn 8: How do you trigger the towers?
I want to share our experiences about tower triggering, which brought us the kill.
Wave 1: Dread (2) | Raid West (0)
Wave 2: Mines (2) | Raid West (0)
Wave 3: Dread (2) | Raid West (0)
Wave 4: Mines (2) | Raid West (0)
Wave 5: Dread (3) | Mines (1) (this one ensures you skip the last ballistic missles)
Wave 6: Mines (0) | Raid West (3) | Raid South (1) (if you skip last missles, both raid towers will explode at the absolute same time as allagan field does)
Wave 7: Mines (2) | Dread (1) | Raid West (0) (Mines and Raid tower explode the same time as allagan field does)
Wave 8: Mines (2) | Raid South (1) | Raid West (0) (Boss should die during or before Mine spawn)
What we experienced: Towers of wave 1-5 last exactly 60 seconds and each stack deducts 15 seconds. Towers of wave 6-8 last exactly 80 seconds and each stack deducts 20 seconds. Allagan fields explode exactly all 40 seconds (cast, 30 seconds timer, little break, cast, ...).
If you skip missles (which would offset the timing by 5 seconds to your negative), all field explosions can be aligned with raid tower explosions, which makes last phase incredibly easy.
Turn 8 is really a time scheduled fight, once you've cleared it you will clear it always. It is like the old Turn 4 in our opinion.
