There has been lots of talk about Gruul and his erratic behaviour. Well, I can assure you that this kill was with all the fun you can expect to have included. During the four nights we spent inside his lair I think I saw him really delay only one shatter, and even then it might have been just his normal behaviour. So, a clean and nice victory for us, something one can be a bit proud of.
After all the small little changes and positioning we tried I have to say that there really is a way to make the randomness of ground slam to be less devastating. Of course this still doesn't prevent an otherwise good start to go totally wrong in a few seconds, but I guess that is why we got all the alchemy masteries and easily obtainable bigger bags to carry more stacks of consumables.
Now what we need is to repeat this a couple of times so we gain enough people with attunement for the Serpentshrine Cavern. Easier said than done.
