-----------------------------------------------------
There are many video show the way to defeat Abyssal Robin level with F2P in the title. I found that they all requires many high-level Sacred Seals. It means they are not newbie friendly. Because I have not played long enough to achieve those Sacred Seals (just one month). So, I have tried to defeat this map with my team and low-level Sacred Seals. The IVs of Micaiah and Veronica are unimportant.

✦ Marth Abyssal Solution
5* Brave Veronica / 5* Brave Lyn (-Atk +Hp) / 5* Hoshidan Summer Micaiah / 5* Legendary Ike
+ SI Used:
- Legendary Ike: Atk Tactic 3 (from Legault, you can get it from Brave Celica but it's a terrible idea), Reposition (from Selena)
- Brave Veronica: Attack+2 (from Cecilia), Spur Atk 3 (from Ogma)
- Hoshidan Summer Micaiah: Axebreaker 3 (from Laslow), Hone Atk 3 (Mathilda or Serra) - Even if you got -Spd Micaiah, the Axe Flier cannot double you because of the Axebreaker 3
- Brave Lyn: Vantage 2 (from Lon'qu or Gordin), Reposition (from Selena), Threaten Spd 3 (from Navarre or Selena) - Threaten Spd 3 is used to reduce the speed of the Archer, and allows Brave Lyn to double him. If you have +Atk Brave Lyn, you do not have to inherit this skill. +Atk Brave Lyn can easily kill him. Luna (from Catria or Walhart).
+ Seals Used:
- Speed +1 on Brave Lyn (In the video, I used Brave Lyn +1, so I have 39 speed instead of 38 speed. You need at least 39 Speed to double the Archer and kill him. So, Speed +1 is needed to raise her speed to 39).
- Savage Blow 1 on Brave Veronica (no need, I just have this Seal)
- Quick Riposte 1 on Ike (Must have)
- Spur Atk +1 on Micaiah (Must have)
+ Summoner Support S on Ike
