This is just a for-fun thread. What is the least synergy build that you can think of?
I’ll start with a couple:
Archer-cannon-musketeer-quarrel shooter
Swordsman-lancer-fencer-doppel (though deeds of vailor is a bit of synergy)
Edit: oh nevermind, seems like QS and cannon has some synergy.
hmmm… hmmm… hmmm…
Wizard > Alchemist > Chronomancer > Rune Caster
This hurts, oof
At one point I wanted to try to make Cannon-Musket work but there’s no synergy and too heavy drawbacks
Mattress and Tiger Hunter don’t really bring the dream to fruition either 
Cleric-Exor-Monk-Pard
Swordie-Lancer-Reti-Murm
Archer-Quarrel-Mergen-Musket
Wizard-Alch-any-any (I love Alch and their nice heals, but there isn’t enough battle support skills to give them a good field role imo)
Retiarius>Templar>Doppel
Mergen>Cannon>Musk
Pardoner>Monk>Miko
Squire>Shinobi>SR
Alchemist>Sage>FF
Alchem has no synergy with otger classes huh?
Well, at least it is somewhat of a standalone support class.
