There are a few BFF’s in Raid like Seer and Lydia, or Maneater and Painkeeper and even Siphi and Rotos but, one of the lesser-known ones is Sepulcher Sentinel and Valkyrie and as killable clan boss teams go, these BFF’s are the best, well except a certain void legendary and a tank of a dwarf, but we are not talking about them, it works on Ultra nightmare and nightmare, and this comp is affinity friendly as well.
This comp includes Valkyrie going last in the turn order, sepulcher sentinel going on a 4:3 ratio along with another DPS going 4:3 as well and two other DPS champions.
The reason we want Sepulcher going on a 4:3 ratio is due to her Block Debuff ability is on a 4 turn cooldown so at this ratio she will always have block debuffs up for the stun and the second AOE attack from the clan boss and Valkyrie goes last so she puts up her Massive shield and her counterattack for both AOE attacks to maximize your damage with the counterattacks and the shield will keep you alive.
Your other DPS champions can be anyone that doesn’t boost turn meter with an ability or a passive like Ninja. If you use them the speed tune will fall out of sync.
Sepulcher Sentinel: 245-246
4:3 DPS: 239-240
DPS 1: 187-189
DPS 2: 185-185
There are multiple variations of this style team simply by altering the speeds slightly. The ranges on this tune are very tight, so make sure to double-check (both on affinity and off).
If using Sepulcher Sentinel (or equivalent 4 turn cd block debuff champion) you’ll want to delay 1 turn (a1, a2) so the block debuff happens on the second attack of her double attack skill (right before the 2nd AOE)
The other 4:3 champion will take a double turn after the stun and before Valkyrie on void and before the stun on affinity.
The 185 champions will go after Valkyrie on affinity.
Recommend delaying valkyrie’s a2 skill two turns (a1, a1, a2) so it activates before the first aoe.
You’ll want to ensure everyone has increase defense before the stun or the other 4:3 champion will take the stun on affinity when the increase defense buff from Sepulcher Sentinel falls off.
If using Sepulcher Sentinel (or equivalent 4 turn cd block debuff champion) you’ll want to delay 2 turns (a1, a1, a2) so the block debuff happens right before the 2nd aoe. She will take her double turn after the stun.
The other 4:3 champion will take a double turn between the AOE’s.
Recommend no delay on Valkyrie’s a2 skill so it activates before the first aoe.
You’ll want to ensure everyone has increase defense before the stun or the other 4:3 champion will take the stun on affinity when the increase defense buff from Sepulcher Sentinel falls off
It will be near impossible to keep increase defense up for the full fight, but you should be able to still get impressive results and last a LONG time with this setup.
