I think I found the most ridiculously relentless team of all time in Arena which isn't original likely but god damn is it crazy.
Bolint - Cowardly Lion - Yuzan - Basher.
Bolint's passive unity bonus:
1 Faction Ally
Whenever an ally hits an enemy, has a 10% chance of placing a [Stun] debuff for 1 turn.
2 Faction Ally
Whenever an ally inflicts a critical hit, fills their Turn Meter by 5%.
3 Faction Ally
Allies will ignore 30% of DEF against enemies under a [Stun] debuff.
This is Bolint's A3:
Attacks all enemies 2 times. Each hit has a 100% chance of placing a [Stun] debuff for 1 turn.
Level 1: Damage +15%
Level 2: Cooldown -1
can be brought down to 3 turn. This is his A3 unity bonus:
Faction Unity Bonus
1 Faction Ally
Before attacking, has a 100% chance of removing all buffs from all enemies.
2 Faction Ally
Fills this Champion’s Turn Meter by 15% for each [Stun] debuff placed by this skill.
3 Faction Ally
This skill will ignore 50% of each target’s RES.
You are getting stunned, and losing all buffs.
You are then getting Basher to A2 you, 3 turn enemy champ 2 turn cooldown on ALL skills.
Yuzan pops block debuffs 2 turn every 4 turns booked.
Lion's A2 now sits at a passive 50% ignore defense before you do literally anything with gear.
TL;DR: Bolint is actually soo god damn powerful, I set this team up in arena, if you see it, ATTACK IT, I wanna see how it does.
