|Zephiel has undeniable potential to be a great tank, boasting both high base HP and Def. This build aims to bulk up Zephiel using Fort. Def/Res 3 and the Water Boost 3 seal; both passives to cover up Zephiel's low base Res.
Zephiel's Eckesachs with the skill refine basically grants a Distant Def 3 skill, increasing defence against Ranged enemies. No reason to replace it.
Given the low mobility of armored units, Pivot and Swap are good choices if you do not have Armor March 3 active.
Bonfire takes advantage of Zephiel's high base Def, which is additionally bolstered by Fort. Def/Res 3, to deal high amounts of additional damage when it triggers. Most of the time, most enemies would fail to deal significant damage to Zephiel due to his massive defensive stats. They would later suffer a punishing blow from his hand.
Fort. Def/Res 3 is the driving mechanism of this build. Abusing Zephiel's high base Attack, it elevates Zephiel's Def to higher levels and covers his low base Res. ≥44 Def can mitigate a LOT of damage from melee users and spells doom for most Bows and Daggers with the built-in Distant Def 3 from Eckesachs. ≥30 Res improves defending from most magic attacks. (Word of warning: Summoning a Kliff can take some considerable luck. But well worth the investment if you use Zephiel a lot.)
Simply put, Wary Fighter 3 from Zephiel's original kit is essential as Zephiel has abysmal Spd. It prevents you from facing double attacks. (Save weapons that allow enemies to attack twice, Brave Celica with Double Lion and units with Swordbreaker 3 active...)
Given his massive bulk, Zephiel is an excellent candidate for Armor March 3. Keep other armored allies close in order to boost movement for said allies and Zephiel himself. If you already have an ally with Armor March 3 or don't have access to the skill, Fortify Armor is a great alternative to reinforce the bulk of armored allies.
The recent Water Boost 3 seal from the Tempest Trials synergizes well with Zephiel's high base HP. If his HP is higher than the opponent's in combat +3, he gains a significant +6 Res combat boost, which paramount to ≥36 Res against Dragon units and ≥42 Res against Magic enemies. It cannot be neutralized since combat boosts are passive. Make sure to keep an eye on his HP!
