My thoughts on the costumes with an initial grading (A/B/C):
Justice: C. She looks like a come from behind hero dealing damage to all, increased if allies are dead, and extra mana generation to fire again. Maybe she could be annoying in a field aid war if she’s in the corner? In most cases I’ll keep using her regular version as I don’t like to plan to have to come from behind with a subpar hero.
Khagan: C. All ally buffs from a slow hero do not excite me too much. I like Guv’s thoughts about a complete change to the costume. Maybe he could be a titan hero where you mana pot him immediately for the defense and mana buff, but neither are large enough for me to want to do that when I can just use Wilbur.
Leo: A. Elemental defense down are rare as is, and can always be used. I’ve been keeping Leo on the bench more often for Costumed/Emblemed Li. I would quickly put Leo back in over her if I got his costume. I’d put this in the top 5 of all 5 star costumes. It takes a hero I generally don’t use and makes him very useful.
Marjana: A+. Elemental defense down at fast speed and decent damage will be very welcomed by many. I can’t imagine anyone will use Falcon over her.
Obakan: C: I don’t get the design of the 60% counterattack heroes. Perhaps it’s to compensate for protecting everyone, but it’s just not enough to deter an enemy for me. If it’s regular Boril, I’ll attack the Wings first. If it’s costume, I don’t care about the counterattack. I’m f2p so I don’t have many alternatives so I do use Obakan from time to time. I’ll take his costume to make him better. In a world of Fast mana, he’s severely underpowered. Perhaps all fast heroes should be designed like him so speed wasn’t so prevalent
Thorne: C: let’s keep describing him as useless, but when he hits, he hits like a truck. He’s an unexciting hero who was not necessarily upgraded.
5 star summary: It seems like the better the hero is in their normal usage, the better a costume that hero got. Marjana has the best costume of the bunch by far. The other heroes are ignored by many and other than Leo, I’m not sure any will make a comeback due to their costume.
Chao: A. I love the Onatel mana steal. I’ve even been using Renfield in class trials just for that special skill. He won’t mana up as quickly as it’s only one target, but this I’ll be using Chao more than my costume Li.
Colen: B-. Basically the same as the default version.
Cyprian: C. Couldn’t have said it any better.
Grimm: B. An attack boost and a higher % damage. This probably helps if you want to use multiple Grimms on one team, but I’d still rather use the defense down default version in most cases.
Gormek: B if you have trouble with minions, C otherwise. Basically Gobler. Against other 4 stars this isn’t super helpful, but as a red hero, he can help against Telly. This version will work better with Wilbur rather than having two heroes provide defense down.
Hu Tao: B+. Not enough to make him a top four star, but I’ll take this version over his default.
That’s a lot of damage in 2 turns at fast mana. Even 300 would make her great. I’d probably still take her over Colen even if she went down to 200 over 2 turns. Just please don’t make her target and nearby.
Sabina: A-. I’m not sure she’ll replace C-Rigard.
I don’t agree that they should necessarily have the same HoT. I would say Mel should have higher HoT than Rigard given his secondary effect isn’t as valuable to me. I do think Sabina’s is low enough that I won’t use her over C-Rigard. If they were even, I’m still not sure she wins.
Scarlett: B. I don’t love the costume other than the rebalanced stats. I do like poison damage in a red stack. Her and Kelile will put some pressure on the enemy.
Dave has a great summary on her costume.
Wu: B?, I like sticking with Wu as a big wildcard. If Wu was very fast, the defense and status ailments would be nice. At average, by the time he fires, I’m coming from behind. Less mana and less attack don’t help that. Maybe you can use two Wus? One to buff defense and one to buff attack.
4 star summary: These are the costumes I may actually get. I already use Chao and Sabina and will hope for their costumes to continue to use those two. Kelile will become an emblem priority if I got her costume. Gormek is lower on my list, but a costume will make him higher in the rotation for me. I’ve been saving a second Cyrprian for months hoping he’d have a good costume. If this is it, I’ll feed him away and open up space.
Dawa: B-. She just won’t replace Bane for me.
Gan Ju: B-. See Dawa comments.
Graymane: C. Won’t use.
Jahangir: B. He gets used in challenge events and this will help.
Kailani: C. I guess this is similar to her current costume, but I only use her for 3 star rush tournaments with no purple.
Nashgar: C. basically the same as his default.
Oberon: A. This is a huge upgrade. For 3 stars without much HP, 324 is a lot of damage to take on, especially in a rush tournament.
Ulmer: A. I’ve used him less as I’ve used C-Gunnar more, but this is a good pairing. Use both and you have defense down and attack up. Good 1-2 with a blue stack that will also have Nordi.
Valen: A. Similar to Ulmer this helps him not overlap with C-Gunnar.
3 star summary: Valen, Ulmer, and Oberon are nice, but the others are useless to me.
In general I love costumes. They’re relatively easily attainable and boost heroes in new ways.
