Uh... Saber. Thoughts on other refines?

Ikr, I thought about the same set for him, he will have Aegis ready all the time unless the enemy has Guard, I was keeping an extra copy of him for fodder, but now I may merge him

It depends on the Special and when Golden Dagger's effect is needed:
- Shield Pulse is great for setting up on turn 1, but it is a wasted slot afterwards.
- Breath skills are useful during enemy phase due to its synergy with Golden Dagger's DC effect. How much you get out of it depends on the type of Special you use. For this example, let's assume that Saber's Special is ready on enemy phase. If it is a defensive Special, the enemy's attack procs the skill, allowing Saber to charge it with his next attack, making it easy to be available for next enemy phase. If it is an offensive Special, the enemy's first attack is wasted, Saber's attack procs the Special. In order to get the Breath's effect to be used, Saber or the enemy need to make a second attack. Easy enough with Saber due to Quick Riposte being a Seal, but harder without it due to his middling base Speed. In addition, taking player phase into effect, the Breath skill is useless, so you need to rely on more precise attack management to have the Special ready again for next enemy phase.
- Special Spiral is the most consistent due to the fact that it triggers its effect out of combat, ignoring Cooldown acceleration and turn usage. The only downside is that it doesn't set him up on the first turn and will likely require him to either engage on player phase to set up for enemy phase or wait until Saber is engaged on so Special Spiral can procs afterwards, maximizing his usefulness from turn 2 and onward.
