nah.
Mine was around 250. As destro on Tugar you need certain things. It’s a very tight encounter for destro. The other one demo for God queen is supposed to be easier. I know other classes have an easier time with Tugar but the key with destro is you need to use fear a lot. So if you have bad haste fear is going to be more than a 1.5 second cast which is not good as you need to interrupt sometimes with fear to conserve your cooldowns. If you don’t you’re dead.
So it’s very item dependent. Also saving shards for Tugar not blowing them all on bile spitters. You should have the ravaged seed pod from EN. The pod will help with leech while giving you more DoT for saving shards. Also Discerning Eye of the Beast will help recover mana as fear costs about 330 mana which will consume all your mana proactively using fear on Tugar.
I did a writeup on the lock forum here: Alright boys, destro down (subpar gear)
But yeah the first couple hundred are just discoveries on what I needed for gear, setting up macros, weakauras, etc. So I’d say for someone not prepared, 200 is a very conservative number of attempts. 300 is probably normal.
