More detailed AI observation, for all skills, sorted by profession. Work in progress.

Any skills that are used in a unique or note-worthy fashion are suffixed with an asterisk (*) and repeated in a separate table at the bottom of each profession's section.


Some general notes:

  • Skills that interrupt will often be postponed in use as long as the target's skill activation window remains visible.
    • The use of interrupting skills on heroes is therefore more effective against enemies that activate a lot of skills in a short timespan, as the heroes are enticed to preserve the interrupts.
  • AI seems to mimic players' reaction time/speed, such as activating skills for which the condition is met just before activation, but removed before the skill can actually be queued.
    • This makes sense as heroes are designed to be substitutes for players, not overly-aware robots.
  • AI seems to be vastly superior to players in terms of interruption time, suggesting an uneven split of replicating player intelligence.
    • When an interrupt moment arises, heroes will often react instantly instead of replicating human-like response times. Therefore using interrupts with no [or almost no] time to take effect will nearly ensure success.
  • AI will consider bonus damage a valid reason to ignore other effects of skills, but still take them into account.
    • Death and/or pressure seems to weigh more than utilizing "secondary" effects.
  • AI does not seem to think [active nor passive] energy management is an important task on its own and will sooner activate skills that can be afforded for other purposes.
    • Heroes with an abundance of energy management will generally outperform heroes with theoretically-sufficient energy management due to the low priority of managing energy.
  • AI does often not seem to care about the potential of area of effect damage and other effects, nor will they decide to change targets to use such skills more effectively.
    • Whereas a player might consider saving area of effect skills for area of effect use, heroes most usually will not and therefore waste the potential of such skills almost by default.

Skills that heroes use that could be used more efficiently[edit]

Axe Mastery
Skill Usage
Agonizing Chop Agonizing Chop Although heroes will not use this skill if the target is not suffering from deep wound, they will not always wait on a skill to interrupt.
If heroes have applied a Deep Wound via another skill but the condition is removed before they start queuing up this skill, they may still queue it as if the condition for it is met.
Occasionally heroes will postpone this skill if the target has recently activated a skill (as long as it remains visible in the skill activation window of the target).
Axe Rake Axe Rake Heroes will use this skill sparingly when the conditional effect cannot be met, but with lower priority than skills with greater/additional effect(s).
Critical Chop Critical Chop Heroes will often activate this skill on recharge, even if the target is not using a skill at that time.
Heroes will not attempt to increase their critical hit rate prior to using this skill.
Occasionally heroes will postpone this skill if the target has recently activated a skill (as long as it remains visible in the skill activation window of the target).
Furious Axe Furious Axe Heroes will use this skill on recharge on the target, even if another nearby target could block the attack to fuel other adrenaline skills.
Lacerating Chop Lacerating Chop Heroes will use this skill on recharge on the target even when the target is not knocked down, often wasting the additional effect.
Swift Chop Swift Chop* Heroes will use this skill on recharge on the target, even if another nearby target could block the attack to apply Deep Wound.

Hammer Mastery
Skill Usage
Earth Shaker Earth Shaker Heroes will use this skill whenever it is charged, but will not change targets to apply the knock down to more foes via the area of effect.
Enraged Smash Enraged Smash Heroes will use this skill whenever it is charged, but will not postpone the use of this skill to counter likely kiting.
Fierce Blow Fierce Blow Heroes will use this skill sparingly, but will not wait for Weakness on the target even if the condition can be applied by themselves or via party members. If the target is suffering from Weakness, this skill appears to take priority over other skills.
Irresistible Blow Irresistible Blow Heroes will use this skill whenever it is charged, but will not change targets to apply the secondary effect on targets that are blocking.
Renewing Smash Renewing Smash Heroes will use this skill whenever it is charged, but only when the target is knocked down. Unfortunately successful use of this skill is often followed-up with another use of this skill, even if the target will have gotten back up before the attack lands, causing the skill to recharge.

Conclusion[edit]

Heroes are like toddlers, give them skills that either can't be used incorrectly or skills that focus on a single target without conditional secondary effects. While they can auto-pilot their way through enemies with the correct skills, more often than not will they power through them less effectively than a human team might. When using heroes, directing them will always increase their use. Fortunately the list of fail-safe skills is sufficient enough to create an effective hard mode set-up.
