His Talent is also worth leveling, as this would improve the conversion rate of his missing health to DMG. Leveling his Ultimate nets you the greatest increase to his damage, so this should be your priority along with his skill. This is how we would prioritize his skills: Swift Harvest (Technique) – Arlan immediately strikes an enemy, dealing Lightning DMG equal to 80% of Arlan’s ATK to all enemies at the start of combat.Arlan’s Talent increases his DMG for every percent of HP below his Max HP, up to a max of 36 to 79% more DMG. Pain and Anger (Talent) – The lower his HP gets, the stronger Arlan becomes.Frenzied Punishment (Ultimate) – Arlan’s Ultimate deals Lightning DMG equal to 192 to 346% of his ATK to a single enemy and 96 to 173% to enemies adjacent to it.If he does not have enough HP when he uses this skill, his HP will be reduced to 1. Shackle Breaker (Skill) – Using Arlan’s skill consumes 15% of his Max HP to deal Lightning DMG equal to 120 to 264% of Arlan’s ATK to a single enemy.Lightning Rush (Basic ATK) – Arlan’s Basic ATK deals Lightning DMG equal to 50 to 110% of Arlan’s ATK to a single enemy.You can get this Light Cone through warping or by buying it in the Starlight Exchange shop for 600 Undying Starlight. Arlan deals more damage the lower his health gets, so anything that lessens the risk of him getting knocked out, the better. Equipping this on Arlan would give him HP recovery along with an overall DMG increase upon defeating an enemy. Most Destruction Light Cones hand their wearer a significant amount of ATK buffs but ‘Something Irreplaceable’ goes a little further. This effect cannot stack and can only trigger 1 time per turn. At the same time, the wearer’s DMG is increased by 24/28/32/36/40% until the end of their next turn.

When the wearer defeats an enemy or is hit, immediately restores HP equal to 8/9/10/11/12% of the wearer’s ATK. Here’s what ‘Something Irreplaceable’ gives to Arlan: It stands above the rest of the Path of Destruction Light Cones because it gives him some much-needed survivability. The 5-Star Light Cone ‘Something Irreplaceable’ is easily Arlan’s best-in-slot (BiS), and the competition is not even close.
