What's the biggest combo you've performed? Include how many cards were used, how many hits it was, and how much damage it did. My biggest combo was:
Cards: 18
Hits: 28
Damage: 3928

Can anyone beat that?

well, i just started my game, my biggest combo so far hasn't been that big but its been:
Cards:15
Hits:12
Damage:1027
it went:
sorcery sophia, weak, medium, strong, vulcadrum, flametongue, weak, medium, strong, scension, wooden club, weak, medium, strong, swallowtail.

Those are pretty good for starters. I have improved my largest combo. It is now:
Cards:18
Hits:32
Damage:4368

WOW! that's a big one. mine have gone up too. the # of cards is increased by one, but now the hits are 19.
it goes:
fire sophia, weak alt., medium alt., strong alt.,vulcadrum, fire club, weak, medium, the jump thingy of milly's, strong, sevenstar dust, blazetounge, weak, medium, strong, cliffsunder.
so the cards are 16, adn the hits 19, and the damage is 2137

Yeah, they get HUGE once you learn an EX Combo with about six cards. Also they get bigger the farther you are in the game. Where are you right now?

my largest combo is this so far.
total cards:13
hits:19
damage:1274
this is the order, starting with guillo
weak attack
medium attack
strong attack
icefan
levinsnake's rise
weak attack
medium attack
strong attack
cliffsunder
ice bloom
weak attack
medium attack
emerald thrush
and that's against an imperial elite soldier.

Actually I may have beaten you all but a fair bit.

49 Hits
21,000 points of damage (close estimation to the nearest hundred)

This includes Relay Combos will all 3 characters during a MP Burst against 5 enemies very strong and high hp:

Level 2 Elemental Equip Cards

Weak, medium, strong B attack cards chained from all 3 characters with previous Ele equips for each character too.

Sagi ExCombo Scension Onslaught + Level 4 The Godling's Rapture (No I did not get The Apotheosis ExCombo for some weird reason).

Then... Milliarde ExCombo Lightning Turkey II

and finally Guillo Equip, W, M, S, Fulgadrum, Goddrake's Thunderclap + Aphelion Dustwake

Mind you, after Guillo's Goddrake's Thunderclap all the enemies except the unluck SOB I dumped all this on were already dust in the wind, and I was just 1 more hit away from the big 50 hits.

Wow! Thats a big combo! So it looks like you used 21 cards to do that. But don't worry, I'll beat you once I make the perfect deck!

BTW, you probably didn't get "The Apotheosis" EX Combo because it requires normal weak, medium, and strong attacks, B's won't work for it.

myne in 3,226 with all three relay combos

mine was 19 cards 32 hits 9332 damage against a upgraded paramachina i think the longest combo thing is dumb in the battle stats tho because the longest isnt always the most powerful

Mine was 25 51 hits about 39,000
on the turn prior to this I gave sagi a berserker drink so he did 20,000 by himself
but I'm not giving away my one attack boss finishing combo

well im up to bout 23k damage now

Level 37
