Chloris: Holy waters for everyone, but especially tank(s), when it uses Fatal Scream, everyone with the spell cursna needs to bomb the Tank(s) as soon as possible.
Ranged Damage should used against Chloris, and if you can find a suitable spot, use the Terrain to block the Fatal Scream ability from hitting more than necessary. Nothing else in the fight is really atypical of basic "Kill it, and don't die" strategy.
Glavoid: Like a super version of Lambtom Worm, if you and the people have experience with Lambton Worm, It'll make the fight much easier. Absorbs certain damage types at certain times. Absorbs Physical when readying TP abilities, and absorbs magical when casting spells.
It's only real dangerous ability is Disgorge. Can do upwards of 3,000 damage, but is easily avoided by tanking the Glavoid on it's ***. It will occasionally reset itself face-to-face with the tank, but it's just a matter of running behind it again to avoid Disgorge. Make sure it is
NEVER pointed at anyone. Disgorge damage can be cut by multiple targets absorbing the ability, much like 1,000 needles or Discoid, but unless it's at least 5 people getting hit, or you have all the Merit Abyssites, it'll still one-shot the majority of people hit with it.
That's about all I can think of that isn't typical of any other fight.
