Which Link Skill should I replace for Zero's?

Here's what I currently use on my Hero (All level 2 except Hayato's which only has one level, and Cygnus Knight at level 6.):

-Cannon Shooter
-Mercedes (No combat value, but the bonus EXP per kill adds up.)
-Demon Slayer
-Phantom
-Luminous (This one maybe? Lose 5% Defense Ignore in favor of 15% Damage Reduction.)
-Kaiser (Some aren't very fond of this one, but considering I use Ginger Ales and am a Warrior with high HP to begin with, I'd say more HP helps.)
-Angelic Buster (I know many don't like this one, but it has served me well. It lets me burn through the two bosses in Dimension Invasion very quickly.)
-Kanna
-Hayato
-Xenon
-Demon Avenger
-Cygnus Knight (This one? It's great for bossing, definitely, but my Hero is going to be stuck doing Dimension Invasion until he can finally do Stronghold unless Commerci has viable leveling spots, or You and I opens up some new areas for him. I don't think any of the enemies in any of these areas inflict status effects. Not even sure if the corrupted Cygnus Knights deal elemental damage despite their elemental associations.)

I'm leaning towards Luminous, Cygnus Knight, or maybe even Kaiser. But what do you guys think?

Cygnus Knight.

Kaiser or AB.

Hayato's.

Kaiser or AB.

I think this is agreeable with.

hayato

hayato or kiaser

How much defense ignore do you have?

Since you are a Hero, I'd lean towards Kaiser since you're in no urgent need for HP. Although tbh AB's link skill is kind of crappy too - it's only good for ultra-burst DPS classes like MM and Lumi assuming you don't have a ton of %Boss/DMG.

Hadriel

Luminous. A Hero has 50% PDR from skills already so 15% wouldn't exactly do much, especially if you don't boss a lot.

Hayato, it's just not very good.

I think Hayato's link skill should be replaced.

I would say Mercedes, but since I'm assuming you still want to level, I'd replace Kaiser's.

How much defense ignore do you have?

29% (Without Luminous' Link Skill.)

Get rid of kaiser's. Most bosses worth doing use % HP attacks so more health wont matter.

But, if you are done leveling, get rid mercede's and use Zero's.

Are you a Dark Knight?

Here's what I currently use on my Hero

Literally the first sentence in the thread lmfao

Literally the first sentence in the thread lmfao

oh well how about that

DONT JUDGE ME

I never bother with my AB or Jett - AB because I never remember to cast it anyway, and Jett cause it tends to be +3-all 3 atk anyway.

I also forget Cygnus even have a link skill lol.

Anyway of those I'd drop AB. Heroes don't burst damage anyway.
