Lvl 50 WHM quest. Help? T_T

[Genesis-xyx]

Cannot beat the level 50 whm class quest. I've tried multiple different approaches, just wondering if anyone can offer tips or advice from their go at it. Thanks!

Your gear looks ok for it. Kill the adds as they spawn and heal the tree in between.

Stoneskin the tree. Your friendly NPCs will not have to heal it and they will kill everything. Throw a couple Holy if bored.

Stoneskin and Regen the tree. Try and heal your allies too because they dish out mad damage and also heal the tree, keeping them alive is the best thing to do.
Don't let the tree fall below 30% HP. Be sure to Esuna the poison as it hits 500 hp per tick. It's rather easy once you pick it up.
I suggest abusing holy and grab mana potions.

P.S: try and Medica2 and hit everyone, the Regen effect is nice.

I just slept adds and healed the tree in the downtime and let the other dudes do the damage. Downside of that was the mana problems but I managed to get it done on my second go.

I just did cleric stance , and killed adds with stone 2
Turn off cleric and pop divine and presence to spam heal tree between add waves.
The biggest problem I had was targeting the damn tree, found it really awkward to click on it.

If you fail it more than 3 or 4 times you get "The Echo" which is a massive VIT and Determination buff, making any fight trivial. As long as this applies to the lvl 50 quest that is, although it should do.

I found that Stoneskin was the kicker here.
The tree has Massive hitpoints - and as Stoneskin is a % of HP, it has a fairly massive effect.

I simply alternated between killing adds with cleric stance and constantly checking tree for stoneskin - went smooth after that.
