This is good for your non-party, specially with Alphen and Dohalim Boost Attack, create 2 when u get the chance, a good example is that if Rinwell and Dohalim can successfully Break Boost two enemies at once their Boost Attack is back fully charge, but must have unlock some 'Increased Boost Gauge from Enemy Downs'.

Stamina Ring

Half AG Cost Chance 20%
Half AG Cost Chance 20% (can be replaced)
Glutton for Battle
Glutton for Battle

For the controlled character (and possibly for the party AI too) everyone can use this accessory, imo experience wise the Half AG Cost Chance at 70% is ENOUGH, but if its not triggering enough for you and you want it to be always guaranteed then upgrade and pump it to 90%, the Glutton for Battle is stackable so if you're not going for the 90% then add another stack of this skill.

Warrior Emblem

Counter Attack Damage +30%
Counter Attack Damage +30%
Counter Attack Damage +30%
Counter Attack Damage +30%

The Warrior Emblem outshines and outperforms the Pierce and Grit Emblem, for overall damage and use against Gigants, Bosses, and regular enemies.

Magic Emblem

Fire Damage +15%
Fire Damage +15%
Fire Damage +15%
Fire Damage +15%

Self explanatory just gonna abuse Alphen's perk Flaming Edge, with Concentration, plus cooking buff from Shortcake, can be pretty stupid, add that with his best weapon or for overkill his Devil Arm... u can easily melt Bosses and Gigants on Chaos Difficulty, just make sure to have a dedicated healer on your Custom Strategy setup, and must be highly invested on unlocking a lot of his passive skills.

Faerie Ring

CP Cost -10%
CP Cost -10% (can be replaced if u have the Starter Pack DLC)
CP Cost -10% (can be replaced if u have the Starter Pack DLC)

Decrease Aggro L (can be replaced)

This can be also used by Dohalim too if u made him also a dedicated Healer in your Custom Strategy setup but that's only if u also got his School Costume DLC, you can also replace Decrease Aggro L with another CP Cost -10% if your CP is draining too fast and or if Kissara is in your party and have Increase Aggro L skill , and if u have the Starter Pack DLC you can replace the other 2 skills with: 2x Half AG Cost Chance 20%, 2x Counter Attack Damage +30%, or Smack Down & CAD +30%.

Mystic Crest

CP Cost -10%
CP Cost -10%
CP Cost -10%
CP Cost -10% (can be replaced if u have the Starter Pack DLC)

This is a good alternative from the Faerie Ring, also if u have the DLC you can replaced one of the skill into Decrease Aggro L, overall its a nice balanced accessory (Casting Time -20%, CP Cost -40%) for Shionne and Dohalim.

Impact Ring /or/ Stamina Ring

4x Counter Attack Damage +30%
or 4x Max HP Damage +15%
For a controlled Shionne and made just for fun that turned out pretty OP, was just spamming Magna Ray and Gravitas Field and everyone was dying quickly, I tried with 4x Pentration +120 and enemies were getting easily interrupted but not dying quickly.

Mystic Crest (Ultimate Version)

4x Counter Attack Damage +30%
thanks u/TyrantWave for pointing this out, this outperforms the 4x Casting Time -5%, even the AI is able to work with this accessory, but also need to test out if the Casting Time -20% from Mystic Crest will be any difference compared from using a Magic Emblem, but so far its currently the best version of Mystic Crest for Rinwell, and also must be heavily invested on a lot of her passive skills.

Mystic Crest

4x Casting Time -5%
I tried experimenting changing the 5th skill with: Glutton for Battle, Counter Attack, Decrease Aggro L, but find all lacking in comparison when she can spam cast faster, Decrease Aggro L would be really great but if u have Kisara in your party with Increase Aggro L and have your Custom Strategy setup to stay away she won't need it.

edit: good starter Mystic Crest for Rinwell, specially for AI use, and still unlocking her passive skills.

Impact Ring (Mob Slayer)

Penetration +120
Penetration +120
Penetration +120
Penetration +120 (can be replaced, or not...)

This accessory turns Law into the Juggernaut, can easily activate his Awakening passive skill, add that with Steel, Sharpness, Concentration, and with turning on and off the right skills, he can turn to the most dumbest OP party member, u can also change the 5th skill with Smack Down to make him more dumb if u have his best weapon or using his Devil Arms but tbh he doesn't need it, also works well with his Boost Attack.

Warrior Emblem

Counter Attack Damage +30%
Counter Attack Damage +30%
Counter Attack Damage +30%
Counter Attack Damage +30% (can be change, or not...)

This one is more kinda' an overall-rounder accessory for Law specially against Gigants and some bosses, damage output wise will outperform Pierce Emblem and Impact Ring, but still need to test with those accessories for regular enemies for his Awakening perk, can also change the 5th skill with Smack Down if so desire to be able to knock down regular enemies or just go for more damage output.

Kisara

Resist Ring

Increase Aggro L
Elemental Defense +60
Elemental Defense +60
Elemental Defense +60

If you have been giving all the herbs that increase Defense and Elemental Defense to Kisara plus her best Armor plus Food Cooking buffs then she can easily tank the entire game on Chaos Difficulty, this accessory outperforms the Revival Ring, Comeback Ring, Protect Ring, even the Grit Emblem with 3x Resistance +120.

Dohalim

Faerie Ring
Mystic Crest
Stamina Ring
