Dan Heng's ultimate ascended form. Permansor Terrae is the finest shielding sustain in Honkai: Star Rail, providing stackable team-wide shields that scale on his ATK stat, summoning the autonomous Souldragon who acts independently to cleanse debuffs and refresh shields every turn, and passively amplifying his Bondmate's ATK and damage output every cycle.
Deals Physical DMG equal to 100% of Permansor Terrae's ATK to one designated enemy. Rarely used in practice since his Skill generates shields and Skill Points are generally spent on the DPS, but a functional damage filler during phases where shields are already maxed.
Designates one ally as the "Bondmate" and provides all allies with a Shield that offsets DMG equal to 20% of Permansor Terrae's ATK + 400 for 3 turns. Shields stack up to 300% of the current Shield value when reapplied. The Bondmate tag transfers to the most recently targeted ally. Summoning the Souldragon and enabling the Empyreanity ATK buff are triggered when this skill is used.
Costs 135 Energy. Deals Physical DMG equal to 300% of ATK to all enemies and provides a fresh Shield to all allies equal to 20% ATK + 400 for 3 turns (stackable). Also enhances Souldragon: while enhanced, Souldragon's actions launch a Follow-up ATK dealing 80% of Permansor Terrae's ATK as Physical DMG to all enemies plus 80% of the Bondmate's ATK as their element type DMG. Enhancement lasts for 2 Souldragon actions (4 at E2).
When an ally becomes the Bondmate, Permansor Terrae summons Souldragon (initial SPD 165). Souldragon takes independent turns: each action dispels 1 debuff from all allies and provides a Shield equal to 10% ATK + 200 for 3 turns. The combined shield cap is 300% of the Skill's shield value. Souldragon disappears if Permansor Terrae or the Bondmate is knocked down. When enhanced, Souldragon additionally deals bonus DMG to the enemy with the highest HP equal to 40% of the Bondmate's ATK.
After using Technique, gains the "Bondmate" buff and inflicts Daze on nearby enemies for 10 seconds; dazed enemies will not actively attack allies. When switching the active character, Bondmate transfers to that character. At the start of the next battle, automatically uses Skill once on the Bondmate character without consuming any Skill Points, immediately setting up Souldragon and shields for free.
Permansor Terrae excels in hypercarry teams focused on a single ATK-scaling DPS. His Bondmate can only be assigned to one ally, so maximizing value means choosing a DPS who takes many turns per cycle. Avoid HP-loss carries like Blade, Mydei, or Castorice, as his shields counteract their mechanics.
