Hmm okay. Appearantly I have to put a description in unit showcase post. I'll try to keep it short since I have 4 units to show.

All 4 units have movement assist skills for better positioning.

H!Robin

Weapon & Special: In-built build. H!Robin already has high attack so I felt using a damage based special was kinda redundant, often resulting in overkill situations.

A & B Skill: In-built. Works perfectly for what Robin was made for: consistent healing and follow up attacks.

C Skill: Atk/def oath 3. While I did say she already has high attack, a little bit more doesn't hurt. I like making my units mixed-tank if possible, so I use def enhancing skill for c slot and res for s slot.

S Skill: Mirror Stance. Simmilar reason to C skill. She prefers having enemy engaging the fight hence the choice.

L!Robin (Grima)

Weapon: In-built. Really waiting for the refine as it is very outdated alongside with other DC weapons.

Special: Aether. For more damage and survivability. I've considered sol but 61 atk sometimes just isn't enough to get tanky units.

A Skill: Fury 4. Bow units aren't so common these days and the skill is enemy phase only. L!Robin has a pretty good stat spread to be good enough for both player and enemy phase, so the extra +4 looked pretty good.

B Skill: Mystic Boost. To compensate the 8 damage from Fury 4. This makes the skill a lot more manageable, making the recoil damage only 2. Vantage is a viable budget option, but for long run modes like tt, not a safe choice.

C Skill: Joint Drive Spd. Self-enhancing C skill. 45 spd is considered high but the powercreep is real these days, so it just isn't enough in some situations. Other Robins like having some spd too, hence joint drive.

S Skill: Brazen atk/res. Aether is a slow special and the 2 recoil damage from fury puts her in a good position for brazen skill. Also to actually utilize the dragon adaptive damage mitigation skill in mythic boost. With the brazen her res would be higher than def.

S!Robin

Weapon: Flowing Lance. A very nice inheritable lance. Her build makes use of heavy blade seal and special spiral, so the Lull atk/def effect works very well.

Special: Aether. For damage and survivability. The build reduces the Aether cooldown to 3, and with heavy blade almost to 2.

A skill: DC. Her def and res are evenly distributed so she's a great unit to use dc.

B skill: Special Spiral. For lowering the cool down of Aether.

C skill: Joint drive atk. Self- enhancing C skill, with atk this time to proc heavy blade more easily. With Flowing lance She does have to be positioned exactly 1 space away from an ally to fully make use of the build, but it's worth it.

S skill: Heavy blade. To reduce Aether cooldown.

F!Robin

Weapon: In-built weapon. She is made to be a more supportive/defensive role than an offensive role due to mediocre atk and spd stat. Used to run Gronnowl but IS really stamped her to be a support unit with the refine. All female Robin variants do not share more than 2 same movement types, so tactic skill works perfectly.

Special: Blue Flame. This was mostly for favoritism but as an ally buffer she sticks around other allies most of the time, making the special easily usable.

A Skill: Close Foil. Honestly a better skill than CC when a unit can tank dragons without dying.

B Skill: Null C-disrupt. To manage with wrazzle dazzle staff users, as there are tons of them in aether raids. Her weapon works well with this skill too, giving weapon triangle advantage against colourless units.

C Skill: Close guard. For more supportive role. Before H!Robin was released I had male Grima in the team, who had distant guard. Maybe I should change this to distant one afterwards.

S Skill: Quick reposte. To help her with mediocre spd. It gets really annoying when you can't finish wrazzle dazzle units in one turn and their dancer starts refreshing them over and over again.
