Petrora goes in at S- for PvE, A for PvP, second form tier 3 and A for HP boost
With high defence, hold ground and disarm being a one-shot revenge sealer / slayerbane this has a very good baseline and can’t be ignored. The entrance is interesting but ultimately I think its main benefit is how it counters any hold ground of those enemies and puts a delay on them dying so you really get a large benefit. Detain is brutally controlling on any defence buffed enemy then disarm countering revenges is a big deal too. So what I’m getting at here is she counters specific things very well (all of which common in PvP) then has the “slayerbane” with tanky stats baseline to fall back on.
Arrest is clearly the strongest move, but the TU is also quite high. I don’t believe it’s your reason to use this monster (in PvP anyway) but it adds to the strong baseline. You can basically kill anything you like on the first turn and getting that monster yourself is likely going to be good. If you can pullback Petrora you can easily arrest more enemies and the SS can also let you do it another time. In PvE Petrora looks brilliant as a way to kill+steal enemies.
I reckon the way to play her is begin by detaining anything you can then arrest a good monster and after that disarm and detain when those moves are possible. Mostly ignore the raid move, but it gives her synergy with protectors both because obviously this does critical damage but also enemies will kill them and become a target for disarm.
With a passive that retaliates the amount of damage dealt by the attack regardless of how much HP Cactus loses (e.g. on hold ground being dealt 2k damage then 2k damage is retaliated) this is like a new version of payback revenge which is much harsher and happens twice unless they have piercing due to hold ground! Then you throw in G.F. Jasmine or anything else to heal it off hold ground and unless they have piercing or instant kill Cactus becomes an absolute nightmare. Surely they just have to ignore it in these cases? Well, Cactus can taunt itself. You could potentially use Arachadiva or Rozaliz to turn into a 100% protect.
The retaliation alone is strong, but without moves to back it up then it would be very dependent on the taunt move. Luckily it doesn’t disappoint there either… Vigor spinebreaker piercing one-shots many of the most common monster types and even if you don’t have vigor then prickly jab deals roughly 300 damage every 10TU (~500 with an earth plant teammate). That stacks up as roughly 160TU to kill mythics in PvP and it has plenty of extra uses. E.g. countering HG/shield/stealth, letting Jasmine heal your GFs, Woolala/Uraniumedhus’ moves that drain HP every turn and more generally it helps kill enemies you’re not able to one-shot with your teammates.
I reckon this is the strongest generic legendary we’ve seen in a while. It doesn’t even need other garden fairies to perform well. What it needs most is teammates healing it.
With the sigil moves based around their current HP (or status buff) this seems like the easiest one to place moon sigils on enemies. Simply do a 30TU attack from another jellyfish then this can place the moon sigil with its own 30TU attack. For that reason I reckon it’s the best we’ve seen and most likely to be the one that makes the strategy possible to use. If you’re facing the jellyfish then this will be the one to kill. I’m giving this a placeholder ranking higher than the others until we’ve got all of them released.
Jel-Chaos goes in at E for PvE, E for PvP and D for HP boost
With less defence than the others and a kill move that has a different condition to the rest (plus higher TU) this looks unbelievably complicated to play with. This whole jellyfish setup is now by far the most complex we’ve seen in the game that I doubt anyone will learn how it works unless they play it for many hours themselves. Jel-Chaos can convert the sigils into one another which might be helpful or not depending on the current situation. I’m hesitantly thinking this jellyfish might help tie together the setup fairly well, allowing you to wiggle yourself into the right position if you can go full big brain. So that probably puts it a above average but not a big standout.
