Green Hunt Dragon (Boss) + Zaphael
The dragon does extreme amounts of damage (10k+).
Similar mechanic to normal green hunt, where the dragon counters after receiving 5 attacks.
Two main strategies:
1. Bring a full-blown cleave team with maximum damage, manual fight waves 1 and 2, blitz down the dragon.
2. Bring lots of tank and damage reduction.
Featured 5*: Noclyn
Noclyn is a pretty good PvE healer, but don't stress her if you aren't having problems in PvE or already have alternatives like Saika.
E7: Haste
Mero is a Sub-DPS / Debuffer / Contrived healer position who, despite her buffs, struggles to move out of her PvE role.
In theory, Mero's S3 is a suitable AOE opener skill that strips two, applies ACC Down, and 85% DEF Down, while being uncounterable.
Her S2 applies Resurgence to an enemy, which causes allies who attack that enemy to be healed. This is more useful in PvE where Resurgence painted on the boss would continuously heal her allies attacking that boss.
In E7 Mero's original was mainly used in PvE teams taking advantage of her high damage multipliers and her decent deck thinning potential manning a role of a damage dealer, a DEF breaker, and a healer in one.
Good base speed of 120 theoretically supports her promotion to an opener role than a mere PvE slave.
Good damage multipliers and 15% bonus base crit rate makes it easy to build her for high speeds.
Lots of useful debuffs, including DEF Down, ACC Down (tricky in PvP), and Resurgence (handy in PvE).
Too many counters already exist for her S3. AOE triggers Urd (Mero's Bleeds will overwhelm Urd's S3 which only cleanses two, but the enemy won't just follow up with Urd alone). Debuff spam triggers Obsidian.
S3 being an attacking skill, she is weak against water element units who are prominent in the meta, as well as evasion units.
Her being fire element makes her less desirable in Red Hunt which imposes a penalty for bringing non-water units.
She mostly works like a sidegrade of existing units such as Bunrica or Aub who are also AOE openers with DEF Down. Bunrica has 9 more base speed and buffs Immunity to the team; Aub is black element and has base accuracy.
(contrived) opener fit: 100% crit rate, as much speed, EHR, and damage stats as you can fit.
PvE fit: Medium to high speed, maximum damage, 55% EHR.
Bond Shop Refreshes
Mero's Bond: Quite literally a straight downgrade of Chaldea's bond: 5% less evasion, and less reliable damage buff. Skip.
SJoyce bond: Lets your Snipers randomly apply DEF Down with single target attacks. Mostly only useful for PvE. Skip.
Petra bond: Competes with Saika bond. Skip.
Bartoz bond: Technically one of the best bonds for Anh, grab if you want.
Theresa bond: Skip
