==Roles==
Roles are supposed to give you an intuitive idea about what a unit can do (better than other units) or what they're useful for. 
Word of warning: They are definitely not all-inclusive of a unit's abilities. Most units can be used in many more ways than what their roles would imply. 
Finally, Boss Killer is the super-role for DPS. This means that a companion with Boss Killer is automatically considered to have the DPS role. 
====
Units with this role either have, or buff, DMG Reduction against either MAtk., PAtk. or a certain class/type. 
Includes DMG Reflection as well.
Nothing stacks as long as it says it does.
Everything stacks with Azit Buffs.
 MAtk. Reduction (Including Mages)
Companion	Class 	Target	Effect
Ein 	Adventurer 	Self 	Reflects MAtk. by 50%
Eline 	Healer 	Party 	DMG from MAtk. -25% (Stackable)
Lawrence 	Shield Knight	Self 	With every attack (after transformation) creates a barrier that absorbs 70% of all MAtk DMG.
Layaul 	Shield Knight	Self 	DMG from MAtk. -40%
Reny 	Healer 	Party 	DMG from MAtk. -20%
Vita 	Healer 	Party 	
 Specific Reduction
Companion 	Class 	Target 	Effect
Rod 	Shield Knight	Self 	DMG from Mages -50%
Ashes 	Healer 	Party 	DMG -25% from attacks that target 4 or more companions.
Ashes 	Healer 	Lowest HP	(Main Skill)Casts barrier that reflects 30% DMG for 4 seconds.
Bronks 	Adventurer 	Self 	DMG from MAtk. -15%
Jin Bachmaul 	Shield Knight	Self 	DMG from Archers -30%, Returns 40% of DMG received.
Seyona 	Archer 	Self 	DMG from Adventurers -25%
Shamu 	Shield Knight	Self 	Reflects 30% DMG from "projectiles"(Archers)
Vernum Grendel	Shield Knight	Self 	Reflects 80% melee DMG (Proportional to own HP)
Honorary Mention: Nohara cuts down the MAtk. of everyone on the field by 50%. It's not technically a DMG Reduction, but definitely more useful than most (as long as you're not using mages yourself).
====
Healers that can serve as the main healing force based on pure heals (or average heal including barriers, granted they have high pure heals as well).
Companion	Justification
Eline 	Heals everyone in the party with Main Skill, which has high potential for Dimension Cube. She also has 20% Crit Rate unlike the normal 10% of other healers. Finally, she also has a party 25% MAtk Reduction buff that stacks.
Elle 	Has the greatest average heals (5-man parties) and a 20% MAtk Party Buff. She also has a "life-saving" skill that is very strong.
====
Boss-Killer companions clearly serve as DPS, so that role is taken as granted. 
Boss-Killer's work as especially great DPS against Alliance Bosses or Dimension Cube Bosses or both. 
Companion 	Justification
Antenore 	The best single target damage dealer in general. She does have a delayed start because it takes time for her transformation to take effect.
Elise 	Not useful against Alliance Bosses. However, she does amazing against Cube Bosses because of her HP Evaporation Skill. Her Main Skill also has a high modifier.
Juhong 	The best Patk damage dealer in general. Single target focus and very high damage numbers. Her ressurection by itself is useful against Bosses (it acts as a single shield for Alliance Bosses). Though, she can be used to deal the final blows to Green Cube Boss if it shouts and wipes the team.
Karan 	High ASPD adventurer that deals of a lot of damage.
Sylar 	Sylar is amazing against all bosses because he has boss-oriented skills that deal additional DMG to them. Also very useful against Advent bosses because of his multiple hits.
Elpaiton, Heidi	Front-liner for Alliance Boss because of Shields (Heidi has lower at 5). Heidi does more damage than Elpaiton.
====
Companions with Shields. 
It costs one shield for every skill you get hit with, apart from DoT damage.
Companion	#Shields
Heidi 	5
Elpaiton 	7
Paiton 	7
Jinryong 	5
Dylan 	5
Taron 	Variable
Taron's number of Shields is variable, 2 for every 5 attacks it deals.
Honorable Mention, Lin: When her HP hits 70%, she gives shields to 3 Allies with the lowest HP.
====
Companions that either diminish enemy heal/barrier effects, or target enemy healers.
Companion	Justification
Ash 	Periodically removes enemy backline barriers and reduces healing effects for them for a short duration.
Lipy 	Damages enemy Healers, stuns them and debuffs their Crit Rate and Healing/Barrier Effects.
Marine 	Reduces Healing and Barrier effects by 20% for all enemies.
Shamu 	Removes barrier cast on enemy hit by Main Skill.
====
Companions that counter Mages. 
Companion	Justification
Nohara 	Cuts down the MAtk. of everyone (including mages) on the field by 50%.
Eida 	She quickly stuns enemy mages. However, her damage isn't very good. Still experimental.
Layaul 	Takes decreased damage from mages. More importantly, stuns enemy mages.
====
