The focus of Season 4 is to add synergy with the new Critical Hit system:
All Champions and monsters now have a chance to critically hit with their attacks, dealing 100% additional damage when they score a Critical Hit. The base chance for a Critical Hit for all Champions & enemies is 2.5%, with some Champions gaining base abilities and/or feats to increase that chance further. Some Champions have formation abilities that trigger when they or other Champions score a Critical Hit. Some Champions have abilities that trigger when an enemy scores a Critical Hit on a Champion.
In addition to the core Season Champions (Regis, Artemis, Pwent, Catti-brie, and Wulfgar), Bruenor, Drizzt, and Jarlaxle received some minor updates to align with the changes. Read below to learn more about these Champions and the details you need to know about Season 4!
The changes outlined below will roll out on Wednesday, June 14th, along with the preview for Season 4: Legends of Mithral Hall. Season 4 officially begins on June 21st, 2023.

Champion Overview
Regis (Seat 2)
Regis has been moderately reworked and now officially features the Gold Find role. While his core buffing abilities have not been changed, his healing abilities have been enhanced to be more useful during long, drawn-out engagements, and many of his abilities are now triggered by the new Critical Hit system.
Critical Hit: Regis' base chance to score a Critical Hit is 20%.
Regis' Ruby Encouragement ability allows him to buff the damage of those in the column ahead or behind him. His Bounty of the Hall ability adds Mithral Hall Stacks to your shared formation pool. It also increases your gold find bonus for each Mithral Hall Stack you have, stacking multiplicatively. His Ruby Healing ability allows Regis to heal the formation whenever he scores a Critical Hit, increasing the heal amount for each Mithral Hall Stack you have.
Ruby Amplification increases the effect of Ruby Encouragement each time Regis scores a Critical Hit. The effect can stack up to 10 times (multiplicatively) and resets when changing areas. Ruby Invigoration stores a charge whenever an enemy scores a Critical Hit against a Champion. This charge increases Regis' chance to score a Critical Hit on his next attack!
Specializations:
- Ruby Encouragement: Choose which column's Champions get their damage increased (ahead or behind Regis)
- Ruby Weakness: Choose which damage type deals increased damage to enemies (Melee, Ranged, Magic)
Artemis (Seat 3)
Don't worry, Artemis has not been adjusted except to have some new feats added for the reward shop & a default uncommon feat to increase his crit chance.
Critical Hit: Artemis' base chance to score a Critical Hit is 2.5%.
Artemis is already a force to be reckoned with on the battlefield. His entry in Season 5 allows him to gain new critical hit feats to further increase his damage!
Artemis' key ability is Observance. He observes and copies the positional formation abilities applied to other DPS Champions in the formation and gains a copy of those abilities on himself at an increased effect, even if he's already receiving that effect! His Jeweled Power ability allows his damage to be increased by 100% (multiplicatively) whenever Artemis kills an enemy. With each trigger of this ability, there's also a 10% chance that Artemis' next attack deals 300% more damage!
Specializations:
- Observance: Friend: Observance's effect is increased by 10% for each positional formation observed and copied from Champions adjacent to Artemis
- Observance: Foe: Observance's effect is increased 25% for each positional formation ability observed and copied from Drizzt Do'Urden or Catti-brie.
Pwent (Seat 5)
Pwent has been moderately reworked (mostly simplified) and now has several abilities that complement the new Critical Hit system.
Critical Hit: Pwent's base chance to score a Critical Hit is 2.5%.
Pwent has a new passive ability that is always active: Bleed. When Pwent attacks, he causes all enemies he damages to bleed, taking a half second of BUD damage every second for the next 20 seconds. While an enemy is bleeding, attacks that target them have a 20% higher chance to critically hit! Can You SMELL That? increases the damage of Champions not adjacent to Pwent. His Battlerager ability grants a chance to reset his attack cooldown when he attacks an enemy already affected by his bleed effect. Gutbuster Recruits increases the effect of Can You SMELL That? each time a Champion adjacent to Pwent scores a Critical Hit. Bruenor, Me King! grants one Mithral Hall Stack to your shared formation pool, and increases the damage bonus of Can You SMELL That? for each Mithral Hall Stack you have.
Combining all of this with Pwent's Round 'Em Up! Ultimate, where he stuns, damages and causes a bleed effect against multiple enemies will make Pwent a potent support for you Season 4 adventures!
Specializations:
- Recruiting Drive: Gutbuster Recruits is now triggered when non-adjacent Champions score Critical Hits instead of adjacent Champions.
- Scents of Mithral Hall: Increases the effect of Can You SMELL That? by 200% for each Dwarf Champion in the formation, stacking multiplicatively and including himself.
- Critical Wound: Attacks targeting enemies that Pwent has caused to bleed have a 40% additive chance to be a Critical Hit, up from 20%.
Catti-brie (Seat 7)
Catti-brie has been heavily reworked and now functions more smoothly as a Support or DPS Champion, instead of being a weird mash-up of the two. Since her Critical Hit ability has been expanded to all Champions, her abilities have been revised to synergize well with Champions who are better at Critical Hits, which is mainly Companions Of The Hall at this point. We revisited her abilities, specializations, and even equipment to make her work well as a support option.
Critical Hit: Catti-brie's base chance to score a Critical Hit is 20%.
Catti-brie's Powerful Draw ability deals additional damage to enemies the farther away they are from the formation. Mark for Death causes enemies hit by Catti-brie's arrows to take additional damage equal to Catti-brie's critical hit damage bonus. Grievous Wounds causes enemies that are marked by Mark for Death to be stunned and take even more damage when a Champion hits them with a Critical Hit. Push Forward increases the damage of herself and all Champions in front of her whenever she scores a Critical Hit. Mark of the Hall grants one Mithral Hall Stack to your shared formation pool and increases the damage bonus of Mark for Death for each Mithral Hall Stack you have.
Specializations:
- Piercing Arrow: Catti-brie's damage is increased by 400% and her arrows hit all enemies on their way to their target. Each enemy hit has a separate chance of being a Critical Hit.
- Big Push: Increases the base effect of Push Forward to 60% per stack and Catti-brie only loses half of her existing stacks when changing areas instead of all of them.
- Critical Family: Additively increases the critical hit chance of all Companions of the Hall Champions by 20%.
Wulfgar (Seat 10)
Wulfgar has been heavily reworked and now has several abilities that complement the new Critical Hit system.
Critical Hit: Wulfgar's base chance to score a Critical Hit is 20%.
Wulfgar has a new passive ability that is always active: He can be used in any Icewind Dale campaign adventure or variant, even if the restrictions would not normally allow him.
King of the Elk Tribe increases the Health of all other Champions by 25% of Wulfgar's Max Health. Clangeddin's Will increases the damage of all Champions in the formation whenever an enemy is stunned. Dumathoin's Will allows Wulfgar to gain Temporary Hit Points based on the boss's remaining health whenever he stuns that boss. Hammer of the Hall grants one Mithral Hall Stack to your shared formation pool. Wulfgar increases the damage bonus of Clangeddin's Will for each Mithral Hall Stack you have. Wulfgar's Smash 'n Grab ability allows the party to increase their damage up to 5 times in an area whenever Wulfgar attacks an armor-based enemy but doesn't remove a piece of the armor.
Specializations:
- Heavy Blows: Additively increases all Champions' critical hit chances by 10%.
- Flag Bearer: Increases the effect of Clangeddin's Will by 100%, and only 50% of the stacks are lost on area change.
- Moradin's Will: Increases the damage of Companions of the Hall Champions by 100%, and all of the Companions of the Hall are available to be used if Icewind Dale is the current campaign, even if they do not currently qualify based on variant or patron restrictions.
Adjacent Champion Overview
Bruenor (Seat 1)
Bruenor has been slightly tweaked so that his Companions' synergy ability works with the new system and has a new name (King of the Hall).
Critical Hit: Bruenor's base chance to score a Critical Hit is 2.5%.
Bruenor now has a new uncommon feat that buffs his Rally ability. He's also gained a new feat at rare, which increases the number of Mithral Hall Stacks Bruenor provides to your shared formation pool.
Jarlaxle (Seat 4)
Jarlaxle has been slightly tweaked to act as an introduction to Critical Hits for newer players.
Critical Hit: Jarlaxle's base chance to score a Critical Hit is 20%.
Jarlaxle has new feats that buff his critical hit chance and damage. He also has a new feat at rare, increasing his CON by 1, allowing him to qualify for Vajra patron adventures.
Drizzt (Seat 9)
Drizzt has been slightly reworked so that his Companions' synergy ability and specializations work with the new system, and his damage can keep up.
Critical Hit: Drizzt's base chance to score a Critical Hit is 20%.
Drizzt's Leader of the Companions specialization now increases his damage for each Companions of the Hall Champion in the formation. His Drow Stalker Specialization now increases his damage for each Drow in the formation. New feats have been added which buff his Icingdeath ability. He's also gained a new feat at rare, which increases the number of Mithral Hall Stacks Drizzt provides to your shared formation pool. Drizzt has also had a balance pass, and several of his abilities and upgrades have been buffed.
