Review
Review
Gunnar is an S-Rank Tank who strongly supports his backline by providing shields and linking with a carry to focus down a single target, while suppressing enemy healing and shielding.
Starting from his Ultimate, Annihilation Directive, it has two effects, Passive and Active. With the Passive effect, Gunnar will create a Doomfield to the ally's location behind him at the start of battle, increasing the ally's attack range and ATK. Then, while this ally remains in the Doomfield, Gunnar links to them, becomes steadfast and prioritizes the target the ally is locked on. With its Active effect, it will launch a Doomsday meteor that damages all enemies and ignites the area, dealing DoT and decreases Vitality for the enemies standing on it.
At Mythic+, when the ally inside Gunnar's Doomfield accumulates a set amount of total damage, Gunnar automatically fires a missile at the locked-on target, dealing heavy damage and healing himself for the same amount dealt. At EX+ 15, the ally on Doomfield gains ATK and becomes invincible while Gunnar's HP is above 35%. At Supreme+, if an already burning area is hit again by Doomsday Meteor, it becomes permanently scorched. The flames no longer expire, and enemies inside cannot heal or gain shields.
Bombing Engine fires Gunnar's cannons six times, damaging enemies adjacent to him and his ally are locked-on. If a Doomfield is active, the ally within it performs six coordinated strikes on the locked-on target, dealing damage based on their max HP and briefly stunning them. As for Absolute Defense, Gunnar gains a powerful shield and grants shields to all allies positioned behind him for a short duration. If a Doomfield is active, it is enhanced, increasing the ATK SPD of the ally within it for some seconds.
Performance in Various Game Modes
Story and AFK Stages - Decent hero in this mode, as hypercarries are commonly being used here, even though other strategies remain dominant.
Dream Realm - This is where Gunnar truly shines, as his lock-on mechanic is most effective against a singular enemy, while also granting a hypercarry a massive ATK boost.
PvP - Tanky enough to survive, especially with Alna, while supporting hypercarries with ATK up, ATK SPD up and Invincible when his HP is above 35%. His Supreme+ passive that denies healing and shielding sounds powerful on paper, but it requires casting two Ultimates, which takes a considerable amount of time to activate.
Investment
Legendary+ increases Gunnar's Ranged DEF and Vitality, moreso for each ally standing behind him.
Mythic+ after an ally dealt enough damage to an ally in Doomfield makes Gunnar fire at his target and heal for the damage dealt.
EX+15 the ally on Doomfield gains ATK and becomes invincible while Gunnar's HP is above 35%
Supreme+ makes launching a Doomsday Meteor on an already burning area permanently scorch it, preventing flames from expiring and stopping enemies inside from healing or shielding.
Conclusion
Gunnar is a strong addition for the supportive frontline archetype that is useful in pretty much every gamemode. If you want to invest in Gunnar, you can start with 1 copy, but for maximum utility, you want him at Supreme EX+ 15 for the additional ATK and invulnerability for the ally on the Doomfield.
