Best Skills and Equipment for Gaius in King Arthur Legion IX

Gaius Julius Mento is with you from the start in King Arthur: Legion IX and, as your leader, he offers more flexibility than most of the other characters. Gaius is a melee DPS who also has a range of support options, plus heavy armor that allows him to operate on the front line as well as in the margins. He is not affected by morality or Loyalty, as he is the boss, so decisions of this kind do not affect him.

The Agile trait gives Gaius +1 movement AP each turn, while he also gets +1 Skill Point every five levels thanks to the Skilled trait. This extra movement makes Gaius perfect for getting around the battlefield fast and taking advantage of game effects such as backstab. Once you have settled in Roma Nova, placing Gaius in the War Council will give him another +1 Movement AP.

Best Gaius Skills in King Arthur Legion IX

You can start to play with your Gaius skill setup as soon as you’ve cleared the first quest in King Arthur: Legion IX. Note that resetting your skills is free and you can do it any time that you’re between quests. After a skill reset, you will always have the basic melee skill Strike along with Barbed Blade (attacks cause Bleeding for 2 turns).  

Level TakenSkill PointsSkill NameDescription
62Jumping AttackJumping Attack does double damage (versus Strike), costs just one more AP, and gives you a free move up to 4  spaces to the target. You can use it every second turn and its only downside is having to place yourself correctly to get to a target. 
62ExecutionThis has a long cooldown (5 turns) but can be devastating—for just 2 AP it kills an adjacent enemy under 40 percent vitality. It's amazing how many times you find yourself 1 AP short of a Strike, so having this in your locker is a great backup. 
62Quick FootedThis makes you immune to Opportunity Attacks, so you can move to wherever you want when you want. If you find an item that gives you this ability, even in a limited way (such as Ancile Sigil below), you can trade this in for Strength (+10 percent Weapon Damage).
61Long Rush (Jumping Attack upgrade)This increases your Jumping Attack range to five squares, giving you unprecedented movement range compared to any other unit. 
72All ResistanceIncreases both Mental and Physical Debuff Resists by 30 percent. This is handy as you'll often find yourself targeted due to your quick movement. 
82JuggernautYou gain +3 percent (cumulative) damage for each tile movement during the turn. As you plan to be moving every round, mopping up easy targets, this should benefit you on most rounds.
91Sinister Blow (Strike upgrade)This gives your basic Strike attack +15 percent damage. It's likely you'll be doing an average of 1.5 per round, so free damage is a no-brainer.
91Evasive (All Resistance upgrade)You'll take -2 Damage from all ranged attacks, which are more likely due to your free roaming skill set that can see you out of tank protection range.
101Ruthlessness (All Resistance upgrade)Regain 2 Vitality per kill. As long as you're targeting weak units such as bowmen you'll get a lot of use from this ability. 
101Scout (Juggernaut upgrade)You gain the Perception skill, alongside getting +1 movement AP. Scout allows you to see enemy traps in adjacent tiles and also find hidden treasure while exploring.
111Scout (Juggernaut upgrade)This second Scout ability adds one more movement AP and increases your Perception skill to 2 tiles. 
112BackstabBackstabs deal an extra 15 percent damage. The amount of movement AP you now have, and being immune to Opportunity Attacks makes getting into Backstab position a breeze.
121Unfazed (Jumping Attack upgrade)If a Jump Attack kills the target, you get 2 AP back. This is a great way to assist your allies, as it puts you back with them to finish off an opponent while costing only 2 AP. 
121Extra Vitality (All Resistance upgrade)Gives you 10+ extra Vitality (depending on your level), helping you stay alive when you head off on your own. 

Best Gaius Equipment in King Arthur Legion IX

There seems to be a randomness to item drops in King Arthur: Legion IX, but look out for these on your travels (or any equipment that gives equivalent abilities). If you have enough, it is desirable to send Gaius into each quest with at least one and preferably two Healing Potions

  • Ancile Sigil: Gaius is all about swift movement, so being able to dodge an Opportunity Attack each turn is massive, which is backed up with +1 movement AP. +2 Unbreakable Armor for adjacent allies is also a nice side bonus as if you’re not moving you’re likely in a defensive position, so this item will benefit you on most turns. 
  • Vexillum Rattus: Any item that straight gives you +1 AP is awesome but this also says that any unit you would leave on less than 10 percent vitality is instead killed. As you’re normally outnumbered, this can often mean fewer incoming attacks at the end of the rounds, which is always good. On the downside, it also takes up your accessory space with Rat Trap. I like this ability (place a hidden trap that damages and slows an enemy that stands in the space) but it depends on what you have to give up for it. 

Beyond these or similar effects that boost your core skills, look for any items that increase Armor and Vitality, or that stop incoming ranged damage. Gaius can often find himself isolated and if he’s the furthest forward in a battle, he can draw the attention from your tanks. 

How to play Gaius in King Arthur Legion IX

Jumping Attack and Execution make Gaius a particularly strong and mobile killing machine able to get off more attacks than most units in a single round. He is perfect for getting to annoying casters and bowmen and dispatching them quickly, but this can lead to him being targeted a lot. Try to use abilities such as Balance from Albina Virgilia to keep him upright, and use excess movement to get into cover after killing blows to further mitigate this.
