Many say she's a dumb healer cause amuse is treated as a buff, but with 2 heals + glancing debuff on 1st skill, she's still great for raids and is definitely recommended. She can be put at the frontline too with good runes but I will recommend putting her at the back as her 2nd skill heals based off her max hp.
Emma has a great AOE heal on her 3rd skill, but is only useful when max skilled cause of the long cd on her last skill. Her last skill also gives defence buff and extra heal will be topped up as a shield which helps. She also has glancing debuff on her first skill which is great.
Support healers:
Support healers are needed to provide more heals for the team. Side healers refer to those with a small heal, or a single target heal.
1) Colleen
If you have read through my guide about debuffs, you will know how valuable she is. Plus, she provides a heal ~30 %(correct me if I'm wrong) on a 3 turn cd when max skilled. Even though she is considered a dumb healer, she is great as a support healer.
2) Konamiya
Her AOE heal is lackluster, but is good enough for a side healer. Plus it also provides an AOE cleanse on a 3turn cd, the least for any cleaser in this game.
3) Delphoi
Her AOE heal is better than konamiya, but is on a 4 turn cd. She provides AOE cleanse + immunity for 2 turns and also provide slow debuff on the first skill which is unreliable as it requires her to crit. She has decent base stats which can be runed to tank the frontline as well.
4) Eladriel
I don't really like him in raids, but I do see people using him. I guess he has the stats to tank the frontline as well as provide a good single target heal, but he doesn't provide much sooo yeah. I won't recommend building him unless you really need a decent support healer who can tank the frontline as well.
In conclusion, for healers, you should bring 2-4 healers. So either 1 main 1 support, 2 main, 2 main 1 support, 1 main 2 support. 2 main 2 support healers etc etc. For me I use 1 main 1 support healer, which is recommended if your team can survive so that you can bring more debuffers/dps to fasten your run.
Cleansers
Cleansers are vital in raids to remove the debuffs and the stun the boss gives. Cleansers should have 100% resist (after lead skills) and should be on violent with as high speed as possible. They should be the fastest monster in your raid team.
Recommended Cleansers
1) Lisa
In my opinion Lisa is the best cleanser for raid. Her cleanse is on a 4 turn cd when max skill, but she lowers the cooldown of her allies then she bring to attack with on her cleanse skill attack command, which is very valuable in raids. Not only can she reduce the cooldown of your monsters, you can also land debuffs from those monsters she bring to attack the boss with. In addition, she also provides glancing debuff on her first skill which is great for raids. I personally am using Lisa as a sort of solo cleanse for my raid team, I have a Fedora but his cleanse + immunity is unreliable cause it is on a 5 turn cd.
2) Konamiya
Konamiya is a great cleanser whose cleanse skill is only on a 3 turn cd. It also heals for about 15% ish once it uses his cleanse which is useful as it can act as a role of being the support healer as well. The downside to it is that his base speed is really slow so you need good speed subs on him to work.
3) Dona
Dona is also a great cleanser whose cleanse skill is also on a 3 turn cd. Dona also increases attack gauge by 15% and an additional 5% for each harmful effect removed, so she can potentially increase the attack gauge of your team by 30% as the boss lands attack slow, attack break and oblivion on your monsters. In addition, Dona provides attack slow and armour break on her 2nd skill which is useful.
4) Anavel
Anavel is a great cleanser as well whose cleanse is on a 3 turn cd when max skilled. In addition, she also heals for a decent amount if your attack power is high enough as it is base off attack power. She also provides a 3 turn armour break on her 3rd which is a bonus. She has high base stats so it is easier to rune her to meet the requirements of stats needed to do r5.
5) Wind Harg
Her cleanse is on a 4turn cd, but she brings attack slow on her 2nd skill as well as attack bar manipulation. Her first boosts attack bar and her cleanse skill casts a shield as well. I have not seen many people using her in r5 so I don't know how good is she. I have heard mixed responses about wind harg. Her kit looks alright as a solo cleanser but to be safe you can run wind harg with another cleanser.
6) Delphoi/Fedora/Velajuel
In my opinion, the 3 monsters cannot solo cleanse for raid, at least at r5 level. Firstly, their cleanse are on a 4 turn cd, For delphoi, her ai is stupid so she will still use her 2nd skill which is useless in raids. Her 1st skill requires her to crit for her to land attack slow. Delphoi can still be use in raids, but definitely not as a solo cleanser. You need to add another cleanser listed abo
