The strategy behind Princess Zody team in HAAT P4?

curious of, not if :)

Leia provides the buff on her basic, not as a special ability, Cody invokes basic attacks with his special, so Leia would hit at least 8-10 times in a topple, quite hard not to gain a buff on at least one of those attacks. And then the buff she provides is crit chance - the most important thing for a Clone team. If you don't score crits with 212th, it won't reset and you'll be ... "kittened".

I dont use this team but I believe leia has a chance to give cc up which means you can spam cody his 212th attack more. I would recommend searching on youtube as I believe there are some good video's that explain the strategy.

The team I use that can solo P4 is resistance: zFinn, res trooper, poe, bb8, rey. (res pilot might be better than rey since he can expose on his special as well)

hope this helps

Problem solved Thank you for enlightening me!

As well as the CC buff, Leia's multi-attack also helps to minimize the cooldown on Cody's special (in the same way that Fives' does when you attack a slowed target).
The goal is that Cody can hit 212th every turn when AAT is toppled

As to your other question on different teams -... yes Resistance is actually better in P4 than Clones. They can solo it with BB8 using 10 or fewer turns of the tank. That setup would be zeta Finn, Poe, RT, RP, and BB8. They can solo it without BB8, but that setup needs a zeta on Rey to daze the B2s and bank exposes. Most use clones in P4 and res in P2 though since resistance is comparatively better in P2 than Clones.

To add some more, Rex can't do much in Phase 4. Effect of TM reduction and hp-dependent bonus Dmg on AAT is negligible, if not 0. Only thing that works is AOE Tenacity up to protect the squad from killing blow of airstrike.
The thing is that the status effect lasts 3 turns while cooldown is 4 turns, and AOE Tenacity up should be properly timed to avoid this short window with no positive status effect in action. Properly timing the AOE buff is quite tiring, and one bad luck can ruin the team. You might get used to it, but replacing Rex with Princess Leia is far more easy and efficient.

I don't have my clones or Resistence quite up to gear to use in Haat yet, but I do Wiggs R2 Lando Leia all with decent mods (~+50 speed) and they regularly get me 3 mil. Never gonna solo, but very easy to run and gets consistent damage.
