The Elder Tree has two parts. The trunk goes to level 340, costs Flawless Droplets and gives flat HP, ATK and Defense to every hero you own. The five Dura's Virtues branches go to level 330, cost Twisted Essence and only boost heroes of one class, each adding percentage stats and three skills. The trunk opens after stage 8-40. The branches open once you've cleared chapter 12 and the trunk is at level 15.
The trunk
| Trunk level | Flawless Droplets to get there | HP | ATK | Defense | Branch level cap |
|---|---|---|---|---|---|
| 1 | 1 | 200 | 0 | 0 | 0 |
| 5 | 10 | 400 | 40 | 8 | 0 |
| 10 | 42 | 800 | 80 | 20 | 0 |
| 15 | 98 | 2,070 | 180 | 40 | 5 |
| 20 | 188 | 4,170 | 330 | 70 | 10 |
| 30 | 428 | 8,370 | 630 | 130 | 20 |
| 50 | 908 | 16,770 | 1,230 | 250 | 40 |
| 100 | 2,108 | 37,770 | 2,730 | 550 | 90 |
| 150 | 3,308 | 58,770 | 4,230 | 850 | 140 |
| 200 | 4,508 | 79,770 | 5,730 | 1,150 | 190 |
| 250 | 5,708 | 100,770 | 7,230 | 1,450 | 240 |
| 300 | 6,908 | 121,770 | 8,730 | 1,750 | 290 |
| 340 | 7,868 | 138,570 | 9,930 | 1,990 | 330 |
The first level-ups cost 1 droplet each and the price rises in steps to 18 for each level from 16 to 20. Every level after 20 costs 24 droplets and adds exactly 420 HP, 30 ATK and 6 Defense.
The trunk's real job past the opening levels is the branch cap. From level 15 on, no branch can go higher than the trunk level minus 10, so a branch at 100 needs the trunk at 110.
Flawless Droplets
Droplets come from collecting and ascending heroes. You get them the first time each hero reaches a tier, and duplicates of a hero you've already ascended give nothing. Only Elite and gold heroes pay droplets, and Dimensional heroes never do.
| Tier reached | Droplets |
|---|---|
| Elite (first copy) | 1 |
| Elite+ | 1 |
| Legendary | 4 |
| Legendary+ | 2 |
| Mythic | 8 |
| Mythic+ | 8 |
| Ascended | 4 |
| Each Ascended star, 1 to 5 | 2 |
One hero taken all the way to Ascended 5-star is worth 38 droplets, and most of them arrive before Ascended: reaching Mythic+ banks 24 of the 38. A gold hero pays its first 6 the moment you get it, since it starts at Legendary.
Right now 195 heroes pay droplets, so a roster with every one of them at Ascended 5-star holds 7,410. That's enough for trunk level 320, which caps branches at 310. Trunk level 340 costs 7,868, so with the current roster the last 20 trunk levels and the last 20 branch levels stay out of reach.
Dura's Virtues branches
Each branch boosts one Elder Tree class. A hero's Elder Tree class isn't always the class on its hero card: many Strength heroes count as Tanks and many Intelligence heroes count as Supports. Common and Rare heroes have no Elder Tree class and get nothing from the branches.
| Branch | Class | Heroes in the class |
|---|---|---|
| Dura's Might | Warrior | 40 |
| Dura's Fortitude | Tank | 43 |
| Dura's Celerity | Ranger | 52 |
| Dura's Sorcery | Mage | 52 |
| Dura's Sustenance | Support | 42 |
Twisted Essence costs
Every branch uses the same cost curve, paid in Twisted Essence from the Twisted Realm.
| Branch level | Twisted Essence to get there |
|---|---|
| 5 | 360 |
| 15 | 2,460 |
| 25 | 7,410 |
| 30 | 11,360 |
| 50 | 27,360 |
| 100 | 67,360 |
| 107 | 72,960 |
| 150 | 107,360 |
| 200 | 147,360 |
| 250 | 187,360 |
| 300 | 227,360 |
| 330 | 251,360 |
The first level costs 50 and the price climbs every level until it reaches 800 for each level after 26, where it stays to the cap. All five branches at 330 add up to 1,256,800 Twisted Essence.
A branch can be reset with a Dura's Virtues Reset Scroll or 300 diamonds.
Branch stats
All branch stats are totals at that level. The percentage stats and the secondary stats stop growing at level 107. Past that point a branch adds only flat HP, ATK and Defense, plus a skill level every 15 levels.

Branch skills
Each branch unlocks a skill at levels 5, 15 and 25. Each skill gets its second level five branch levels later (10, 20 and 30), then another every 15 levels: the first skill at 35, 50, 65 and so on to 320, the second at 40, 55 and so on to 325, the third at 45, 60 and so on to 330. That's 22 levels per skill.
| Branch | Skill | Unlocks at | At skill level 1 | At max level |
|---|---|---|---|---|
| Might | Shattering Force | 5 | Enemies you hit lose 24% of their health recovery rate and take 15% more damage for 3 seconds | 40% and 35.5% |
| Might | Shield of Fortitude | 15 | Shield worth 15% max HP for 5 seconds when an enemy casts an ultimate, once every 16 seconds | 38.5% max HP, once every 12 seconds |
| Might | Blood Thirst | 25 | Life Leech +14 for 5 seconds after the first ultimate | Life Leech +35.5 |
| Fortitude | Clawback | 5 | Below 30% HP for the first time, recover 2.5% max HP per second for 10 seconds | 3.9% per second for 25 seconds |
| Fortitude | Sundering Slam | 15 | Each 30% of max HP lost releases a shockwave: 3% of each enemy's max HP as damage and Haste -30 for 3 seconds | 10% of max HP, Haste -50 for 6 seconds |
| Fortitude | Life Flash | 25 | Extra 9% max HP whenever an ally heals you, once every 11 seconds | 22.5% max HP, once every 7 seconds |
| Celerity | Impending Danger | 5 | Below 50% HP for the first time, Dodge +80 and Haste +10 for 6 seconds | Dodge +150, Haste +50 for 11 seconds |
| Celerity | Maim | 15 | Hitting an enemy under 50% HP adds 140% damage that can't be dodged, once every 3 seconds | 335% |
| Celerity | Rapid Surge | 25 | Damage an enemy in the 5 seconds before it dies: recover 4% max HP and Haste +80 for 4 seconds | 27% max HP, Haste +140 for 6 seconds |
| Sorcery | Astral Focus | 5 | ATK +10% for 3 seconds after each ultimate | ATK +29.5% |
| Sorcery | Astral Tide | 15 | First ultimate gives every ally 30 energy | 195 energy |
| Sorcery | Power Surge | 25 | First time below 30% HP, recover 40 energy and ignore control for 1.5 seconds | 235 energy |
| Sustenance | Savior's Gift | 5 | First ultimate shields the most injured ally for 220% of the hero's ATK for 7 seconds | 610% of ATK |
| Sustenance | Life Kindle | 15 | Healing an ally also heals the most injured ally for 100% of the healer's ATK, once every 10 seconds | 330% of ATK |
| Sustenance | Defiance | 25 | 15 seconds into battle, recover 60 energy and ignore control for 1.5 seconds | 315 energy |
Astral Tide loses 60% on every repeat that reaches the same ally within 10 seconds, so several Mages casting their first ultimate together gain less than the numbers suggest. Rapid Surge tops out at skill level 21 at branch level 315. At branch level 330 the third Celerity slot holds a second copy of Impending Danger instead of a 22nd level of Rapid Surge, so a Celerity branch at 330 loses Rapid Surge.
What to level first
The trunk mostly takes care of itself, because droplets only come from ascending new heroes. Spend them as they arrive. The trunk's flat stats are small next to a late-game branch, and its main value is lifting the branch cap.
Branches are where the choices are. Getting a branch to 25 costs 7,410 Twisted Essence and unlocks all three skills, which is under 3% of the 251,360 a maxed branch costs. Bring every branch your main team uses to 25 before pushing any one of them higher.
Level 107 is the next checkpoint. It costs 72,960 Twisted Essence per branch and finishes every percentage and secondary stat. Beyond it, each 15 levels buys one skill level for 12,000 essence, plus flat stats.
When deciding which branch to push, count the heroes in your regular lineups by Elder Tree class, not by the class on their cards. A branch only pays off for heroes of its own class, so the class that covers your damage dealers and the most lineup slots should get the essence first.
