So I decided to spend 2,000 Ancient Mana to get the full withered army and started the training scenario. Everything was going fine until I left the first room, then 18 out of 20 withered just vanished. I even killed the Volatile Wraith on Heroic without any issues.
Anyone else had this happen?
Either they killed by the volatile add aoe, or you left them behind. Heroic world tier withered die by one hit from anything.
Also by chance they survive on low hp, there is a high chance they just got feared and run away unless u click on it.
The heroic tier for withered training is hella bugged, it isn’t normal how they die so fast.
There’s definitely a problem with it. I practically one shot everything in there now and my withered still just die in huge numbers randomly sometimes.
EDIT: Listen to Noztra’s advice below
I discovered how messed up the HC world tier version of the withered training was few days ago, since then I have only ever done the scenario on the normal world.
Though something even seems bugged with that.
I did this withered training lots during the actual Legion expansion, and there definitely seems to be a problem with it in the Remix version.
Even on normal tier starting with full sized withered army with many upgrades, I can nuke a boss in seconds, yet my withered will still go from 100% HP to average of 14-20% between all of them, on just that fight. That’s even though the boss didn’t even have time to get a spell off.
Now this was definitely not like that in Normal Legion expansion.
I can still complete the scenario just fine, but losing withered out of nowhere can mess up the amount of chests you can send back at the end.
Thankfully the achievement only rewards bronze 
I finally completed the achievement yesterday and managed to over 400 points aswell
Get to 740 and zerg it pretty much
Wait for your withered and when an aoe is cast on you run away from your army
Keep them on follow
The elementals aoe is interruptible
The key is to make sure they’re dead before the second cast
If you have a stun, then third cast
I had a huge problem with the Witchered Army as a tank, because already in the second room almost all my mobs were dying. I switched to DPS and went through almost the whole thing without any losses (just for opening chests). I think something’s messed up with the tank scaling.
I might give it a try again on 740, thanks for the tips! I guess I’ll gotta play extra carefully with the army as they’re a bit squishy then.
True! But I wanna get it nontheless 
It isn’t mostly about getting to 740 gear, but to how much versa you got in the Infinite Power buff. If your stats are low in the buff, the gear isn’t going to get you even close to what you need to clear this in Heroic World Tier!
Perfectly doable, had score of 493 for the first try today on Heroic Tier. Make sure you have collected all the upgrades from chests in normal runs first…
Only thing I did was to avoid the first two locked rooms to the right and left and before getting to the Dro’s Key mini boss, I already had over 300 score…
740 ilvl and 93 IP, used the 1300 mana option for 15 Withered.
After following Noztra’s advice to take a few days getting all the upgrades on Normal, this was a breeze. I think it took 4 Normal runs to get them all. Plus, I’ve got my Vers higher by now too so burning the bosses was a bit easier.
I finished with the max 700 on Heroic and I REALLY messed up at the start and got most of my original 20 killed.
The health upgrades and the upgrade that reduces the chance they will run away when they get hurt are key.
Didn’t put the Withered in Mayhem once. I recommend not using it so you don’t have to start chasing them around. You can do enough damage yourself or just wait until you have more versatility to get the achievement.

So obvious, never crossed my mind, so thank you so much for the reminder
