Can't wait for dumb tanks to try and pull in extra mobs and reset the boss
For hunters there is another tip, though it does require it being timed slightly, but you can feign it. Not acquiring a barrel at all. Least from my experience.
Druid can shapeshift out of form but not into
Eudora also fires from Left to right. Approach from the right when chasing.
Paladins shouldn't use Freedom to early. If you cast it while it's not on the player yet, the barrel stands still and is still active. So if someone walks through he gets trapped.
I was able to use Dispersion on my S-Priest to avoid the barrel as well.
Mage blink also works for the barrel
For blackout Barrel - if its casted on them, Evokers can cast Deep Breath before the barrel gets on them.
If you get targeted with the barrel you can run on top of someone else and have it go onto them instead. Easy way to troll guildees.
Priests can use dispersion, yes you have to cancel the effect after but you break out of the barrel and can move - even get a little heal to boot and movement speed for that next ability overlap to not die or survive a single hit from grapeshot.
Like others have mentioned Eudora shoots the grapeshot in a clockwise direction after she jumps around to a new location. So if you have to run to her you should do so so that you only take 1 hit by running to the right side of her location.Rauol also gets "good brews" thrown near his location which are highlighted by a blue circle. If a party member stands in one you get an 8 second buff or either 30% crit or haste.Additionally the green caustic brews are thrown. If the tank can position the boss to get hit by one it also puts the same dot on the boss as a party member would get. Which is huge for tyrannical weeks.
Very cool clips. Incredible visual guide. 10/10
Warlock movement impairing immunity, Soulburn coupled with Demonic Circle: Teleport
Surprised the comments about Eudora's firing pattern aren't included in main article but adding to the ones above that she always does Grapeshot from HER left to right so you always want to approach her from YOUR left (facing her) when she jumps to a corner
