Bertram - Dread Cavalier: Basic Information
| Color / Weapon Type / Move Type | |
|---|---|
| Rarity | |
| What Kind of Character Are They? | ・Refined Clouded Blade grants Bertram Canto, adaptive damage, bonus stats, true damage, true damage reduction, healing per attack, and inflicts stat debuffs, Guard, and a forced guaranteed follow-up attack on all foes within 3Rx3C of Bertram. |
Bertram Skills at 5★
|
Might: 16 Range: 1 Enables 【Canto (Rem. +1; Min 2)】. Calculates damage using the lower of foe's Def or Res. If unit initiates combat or the number of allies adjacent to unit ≤ 1, grants Atk/Spd/Def/Res+5 to unit and reduces damage from foe's attacks by X × 4 (excluding area-of-effect Specials), and reduces damage from foe's Specials by an additional X × 4 during combat (excluding area-of-effect Specials; X = number of spaces from start position to end position of whoever initiated combat; max 3), and also, when unit deals damage to foe during combat, restores 7 HP to unit. |
|
Cooldown Count = 4 Boosts damage dealt by 80% of unit’s Def. |
|
If foe uses sword, lance, axe, dragonstone, or beast damage, neutralizes foe's bonuses (from skills like Fortify, Rally, etc.) during combat. |
|
At start of turn, if unit is not adjacent to an ally, grants Atk/Def+6 for 1 turn. |

◯ = Stat gains +4 with a superboon, ✕= Stat goes down by -4 with a superbane, - = No assets or flaws
| See the IV Checker for All Units | Trait Fruits—How to Change IVs |
When using an Ascendant Floret, we recommend getting the next superboon if it fits the hero. If not, consider what stat your hero needs most.
Neutral IVs by default!
As a hero obtainable only through Grand Hero Battle, Bertram will always have neutral IVs by default. The only way to access IVs for this unit is through using Trait Fruits.
+Def/-Spd
The best IVs for Bertramh are +Def and -Spd. Bertram's role is a physical tank, and he excels in that role and that role alone. Boosting his Def is the highest priority in making Bertram a viable unit.
Both his Spd and Res stats are the lesser important stats for Bertram, but we chose to go with -Spd due to his role as a tank; he may need to absorb a magical hit or two.
+Def for a +10 Merge
We recommend a +Def IV when merging Bertram to +10 for the same reasons mentioned above. Bertram's role is a physical tank, and Def is the most important stat for that role.

How to Use, Explanation
This premium build focuses on Atk/Def stats and allowing Bertram to deal significant damage while retaining physical bulk. Emblem Sigurd ring and Shadow Shift 4 provide additional mobility.
Bertram Best Weapon Refine
Effect of Bertram's Refined Weapon
| Exclusive Weapon Effect from Refining (Special Effect Type) | |
|---|---|
| SP: 400 | |
| Might: 16 Range: 1 HP: 3 Enables 【Canto (Rem. +1; Min 2)】. Calculates damage using the lower of foe's Def or Res. If unit initiates combat or the number of allies adjacent to unit ≤ 1, grants Atk/Spd/Def/Res+5 to unit and reduces damage from foe's attacks by X × 4 (excluding area-of-effect Specials), and reduces damage from foe's Specials by an additional X × 4 during combat (excluding area-of-effect Specials; X = number of spaces from start position to end position of whoever initiated combat; max 3), and also, when unit deals damage to foe during combat, restores 7 HP to unit. For foes within 3 rows and 3 columns centered on unit, inflicts Atk/Spd/Def/Res-5 on foe, inflicts Special cooldown charge -1 on foe per attack (only highest value applied; does not stack), and foe suffers guaranteed follow-up attacks during combat. At start of combat, if unit's HP ≥ 25%, deals damage = 20% of unit's Def during combat (excluding area-of-effect Specials).  ：500  ：200 |
|
We recommend the Special Effect Refine for Clouded Blade
Refined Clouded Blade inflicts long-distance debuffs to all foes within 3 rows and 3 columns centered on Bertram and also grants Bertram bonus true damage during combat.
These effects are significant enough to warrant refining Clouded Blade instead of keeping it in its base form.

Bertram Roles, Strengths, and Weaknesses
Bertram Roles
Bertram is a close physical attacker (range = 1). Therefore, when not accounting for the Weapon Triangle, the amount of damage he deals will be equivalent to his Atk minus the foe's Def stat.
Bertram Strengths
Refined Clouded Blade provides offense, defense, and support
Bertram's refined Clouded Blade provides multiple effects that help both Bertram and his allies in battle.
Below is a summary of these effects:
| Condition(s) | Effect |
|---|---|
| Always |
・Enables 【Canto (Rem. +1; Min 2)】. ・Deals adaptive damage to Bertram's foe. |
| Bertram initiates combat OR the number of allies adjacent to Bertram ≤ 1 |
・ Grants Atk/Spd/Def/Res+5 to Bertram. ・ Heals Bertram 7 HP per attack. ・ Grants Bertram up to +12 bonus true damage reduction based on distance travelled. ・ Grants Bertram up to +12 bonus true damage reduction on Specials based on distance travelled. |
| For all foes within 3 rows and 3 columns centered on Bertram |
・ Inflicts Atk/Spd/Def/Res-5 on these foes during combat. ・ Inflicts a Guard effect on these foes during combat. ・ Foe suffers a guaranteed follow-up attack during combat. |
| Bertram's HP ≥ 25% at start of combat | Grants Bertram bonus true damage equal to 20% of his Def. |
Refining Clouded Blade makes Bertram a versatile unit, capable of going on offense or defense while also providing support for his allies.
Bertram Weaknesses
Stats other than HP and Def are all mediocre
Bertram may have high HP and Def, but all of his other stats are rather low, especially for a 5th generation unit. His Atk at base 37 can be salvaged with the correct passive skills, but his Spd and Res are too low to make good use of at base 27 and 26 respectively.
Needs investment
Since Bertram was not released as a 5★ unit, he does not possess premium fodder. For him to be able to make an impact in competitive maps, Summoners will have to invest on him quite extensively.

Bertram as a Source Hero
| Value of Skills | ★★☆☆☆ |
|---|
Bertram really only has Instant Sword+ as desired fodder. His other skills are either very niche or could be obtained elsewhere more easily.
Instant Sword+ is a good inheritable weapon, so save your Bertram copies as combat manuals in case you need it.
