Strategy guides have covered mostly the Storm Rider/Time Warden/Whelps combination, and the one from Tank Spot imo has the best desciption, so it's no use pasting the other ones:Wowpedia wrote:Four friendly drakes and a pack of whelps are imprisoned in the area where Wyrmbreaker is engaged, but only three of them can be engaged. The exact combination of available drakes is randomly selected. When freed, each drake or whelp pack will put a debuff on the boss.
The drake composition of the fight is randomly selected and, like classic Nefarian, getting a difficult combination of adds means you must deal with it until next week.
The Nether Scion
Pre-fight, applies a frenzy buff to Halfus Wyrmbreaker (+100% attack speed). When freed, reduces raid damage dealt, but will also cancel out Wyrmbreaker's frenzy attack.
The Time Warden
Slows down the speed of the protodrake's fireballs, but, but also roots players.
The Slate Dragon
Gives Wyrmbreaker his Malevolent Strikes ability, which causes a stacking healing debuff. Once freed, periodically stuns the whole raid for 15 seconds and does the same to Halfus.
The Orphaned Emerald Whelps
Reduces raid and boss damage dealt by 50%.
The Storm Rider
Gives Wyrmbreaker a Shadow Nova ability which deals AoE damage and knocks people back.
Have found a comment on the other combination tho:
All in all, we'll see by ourselves how it looks like, but probably it's good to remember about:Zorash wrote:Last night we had Storm and Nether up and this fight seemed 100x easier. We 1 shot it and healers had 60% ish mana left when he went down. The time-bound really is the nastiest raid damage drake. Oof.
With Nether/Storm we popped whelps and Storm at the start, burned storm with lust, then popped nether to negate the melee buff on Halfius. We burned Nether and then it was cake. The whelps were mostly dead from incidental AoE and tank damage, and halfius was hitting like a kitten with no real AoE to speak of. Definitely a nice combo compared to having the massive raid AoE to deal with. Just don't miss those kicks.
For interrupters:
+ have to set up a interrupt rotation for Shadow Nova (if we have Storm drake up)
+ have to use cooldowns to break the third Furious Roar stun to interrupt the immediate Shadow Nova
For healers:
+ tanks should have a cooldown used on them before Furious Roar
+ start of the fight is intensive, so pop Shadowfiend on pull, and it should be ready again 60s to the enrage
+ bug everyone to click on the Lightwell after a Shadow Nova if there is one!
For all:
+ stay out of the fires!
