Last time I did it I was very overpowered (not level-wise, just jobwise). I was maybe lv 20, 22 tops or so. But I had a summoner who knew Odin. Start of battle, Gafgarian attacked Agrias, then I had Mustadio Paralyze him. All the other units on the bottom level kinda.. grouped up to attack my ninja who I threw into the middle of them. Poor guys didnt know what hit him, bam Odin lands and 5 guys take 200+ dmg. Then all was left was 2 time mages and a paralyzed Gafgarian. My fastest Execution battle clear ever lol.

But if all else fails and you cant get by, just give everyone auto potion for this battle, theres a lot of units and you need lots of healing if you dont have a summoner who can take out a large group all at once. Having a fast unit with Blade Grasp to charge in first and group up all the knights/archers semi-close to each other can make it easier to drop a big summon on em. Blade Grasp ensures that unit will never die to the knights/archers. I also like putting Agrias on the 2-spot under the bridge to start (away from Ramza). If you are lucky, you can drop a Stasis Sword on 1 of the Time mages above, and get Stop to land. Thats 1 less unit to deal with.


Edit: And what the heck is up with "l o l" = "I cried aloud with Mirth and Marriment or whatever" hehe
