|This build focuses on maximizing the amount of ORKOs Joshua is capable of achieving on Enemy Phase. With the combination of Audhulma's CD-1 effect and Quickened Pulse, Iceberg becomes a 1 turn Cooldown Special, which Joshua will be able to immediately activate after taking a single hit, making for a devastating counter attack.
Distant Counter is the obvious and undisputed best A skill for this set, as Joshua would not be able to function as a ranged check without it.
The B slot is actually left open for two recommended options, being Wrath 3 and Quick Riposte 3. Joshua only has to lose 10 HP to be put into Wrath range (Unless he's merged, in which case he must take 11 damage), letting him gain 10 extra damage for his Iceberg, which already does 16 damage at base, bringing up to a respect demanding 26 damage. Quick Riposte 3 is here more of less as a budget option if one cannot acquire Wrath 3 to give to Joshua. It should be noted that in more scenarios than not, this lowers Joshua's damage on Enemy Phase and should thus not be used if Wrath is available, but is a usable alternative.
The C slot is used for Def Ploy 3. This skill lets Joshua acquire more ORKOs, assuming that he's able to effectively ploy the enemy unit(s) which shouldn't be a very difficult task due to Joshua's fantastic 33 Res after taking Audhulma's +5 Res boost into account. As this build is focused around getting as many ORKOs (or even better, OHKOs) as possible, Def Ploy 3 is highly recommended.
The S slot is Quickened Pulse, with no competition. While Distant Def 3 helps him take a few more hits, namely from Bridal Cordelia and Trick or Defeat Jakob, Quickened Pulse puts his Iceberg on a 1 turn Cooldown at the start of the game, letting him activate it after taking a single hit, regardless of range, and lets him retaliate with a 26 damage Iceberg if Wrath is used and ready to activate
This set is used entirely for Enemy Phase baiting and is not intended to shine on Player Phase, so try and use Joshua to bait an enemy mage or archer that is unable to kill him, and retaliate with a counterattack that will more than likely slaughter its target.
