Ple-Sen
I see, "the most honest lord" — swore allegiance to one, instantly switched to another. With friends like these, you don't even need root enemies.
Was thinking of reading Ples's guide today, but honestly, the desire to play this is really dropping. Everyone has some super-duper giga-abilities, both personal and global, looted epics from the merchant, and here you are sitting with stock garbage, enduring until the last turn, catching debuffs and eating crap, just because fate has it that you get pissed on.
Lester got a free doctor and a super cool painting. On top of the one Lester has from the start, which no one else can boast of.
Axel got a cool wyvern.
Ambrose got free trainability and a good bonus for 99% of battles.
Besides, you have 18 potential Knights, and Lester specifically has a chance to get a very synergistic dagger if he goes to hit Azarta.
