William in Last Asylum: Plague
William is an SR Warrior damage dealer, and every one of the 5 tier lists that cover him puts him in tier C. He swings a sword and sends wind blades at enemies, and he belongs to the starter group that carries the opening chapters. The page covers his skill numbers, which skills to level and when to replace him.
Do not mix him up with Billy. Billy is a UR Warlock Tank with his own page, and the two names are often confused in search.
William Stats
William belongs to the Warrior faction, has SR rarity and plays as a damage dealer. Level 1 starts at 19 ATK, 1,211 HP and 12 DEF. Command (CMD), the number of troops the hero leads, starts at 50. With level 150 and 50 star steps (10 full stars) done, William climbs to 12,299 ATK, 760,343 HP and 7,986 DEF, with 350 CMD. By these numbers William sits 25th for ATK, 30th for HP and 29th for DEF among 31 heroes. The weakest stat is HP, a place among the last five of 31.
Only level and star upgrades are counted in the table. Ravens, gear and base buildings come on top in battle, which lifts the full build to 524,421 power. Full-build power puts William 29th among 31 heroes, inside the last five. Level 150 on its own, before any star, gives 9,568 ATK, 591,400 HP and 6,213 DEF. Unlocking William takes 10 shards, the 50 star steps take 975 more. Each SR Hero Omni Shard is worth 1 hero shard. Full stars open the way into the Hall of Honor, with an honor level cap of 600.

William Skills
William swings Sword Gale every 0.87 seconds. His kit has three skills that take badges and a support skill, and the SR cap is level 30 for each skill. The upgrades column names the star for each step. The skill level and star rules that all heroes share are on the heroes list.

Whirlwind Blade is the area skill: it hits every enemy in its path for 259.35% to 617.5% ATK and recharges in 10 seconds. Twin Wind strikes one target twice and recharges in 5 seconds, and it scales from 165.9% to 395% ATK. The text in the table lists a flat 30 percent for Twin Wind, while the upgrade row shows the real range, 711% ATK at the top. Unyielding gives a flat 5 percent to ATK, HP and DEF after level 30 and star 40.
Skill Priority
The tier lists do not rank William's skills, so this order follows the numbers in the table.
- Twin Wind. With a cooldown of 5 seconds, it is the skill he fires most. Upgrades at stars 15, 35, 50 lift it to 711% ATK at star 50.
- Whirlwind Blade. It is his area hit, and it reaches 1,111.5% ATK at the top. Level it second, because a monster wave is the one place where William is useful.
- Sword Gale. It upgrades at stars 5, 25, 50 and tops out at 315%. Auto attacks matter least while the two skills are recharging.
At the top, Twin Wind works out to 142.2% ATK per second and Whirlwind Blade to 111.15%. The area skill hits more than one enemy, so the first number understates it against groups.
William Build and Upgrades
A full William is not a good use of resources, so build him in steps. The shard bill reads 75 for star 20 (skill level 5), 475 for star 40 (Unyielding) and 975 for star 50. Badges are a separate bill: 170,200 per skill to reach level 30.
| Skill level | Hero star needed | Badges for that step |
|---|---|---|
| 5 | 20 | 300 |
| 10 | 30 | 1,200 |
| 20 | 40 | 6,900 |
| 30 | 50 | 18,400 |
Keep him at the level that clears the current stage. One beginner list says to hold SR heroes at exactly the level you need right now and to send the rest to the main squad. William has no exclusive weapon or awakening, so gear is the only extra. Armor goes on first when you have spare pieces, and the gear page lists the slots.
The video below is a walkthrough of the start of the game, where the starter heroes are used. It is no William guide.
How to Get William
Ten William Shards unlock him, and nothing about the server age blocks it. The story text has the clinic bring him in. Shards drop from Tavern recruits, with SR Omni Shards as a substitute. What to do during the opening days is in the beginner guide.
William vs Claire
Claire is the SSR Warrior damage dealer who usually takes William's slot, and she is available from the start.
| Stat | William | Claire |
|---|---|---|
| Rarity, faction, role | SR Warrior Damage dealer | SSR Warrior Damage dealer |
| Power at full build | 524,421 | 685,150 |
| Attack interval | 0.87 s | 1 s |
| Skill level cap | 30 | 40 |
| Auto attack at the top | Sword Gale: 315% ATK | Holy Banner: 594% ATK |
| Strongest skill | Whirlwind Blade: 1,111.5% ATK | Celestial Judgment: 2,266.29% ATK |
| Passive | None | Call of the Brave: the 3 highest-ATK Warriors deal up to 24% more damage to monsters |
| Support skill | +5 percent ATK, HP and DEF | +10 percent ATK, HP and DEF |
| Tier list rating | C in 5 of 5 lists | A in 3 of 5 lists |
Claire has 160,729 more power at full build, a higher skill cap and a passive for monsters. William only wins in the first days, when Claire has not dropped yet. After that, move his shards and badges to her.
Best Team for William
No ranking lists William in a recommended squad. The squads below are stopgap examples built from roles, and none of them comes from a ranking. William is a stand-in Warrior damage dealer, so a Warrior squad can take him until the real carry arrives.
| Stage | Heroes | Why |
|---|---|---|
| First days | Arthur or Bella, William, Celia | All Warriors, so the faction bonus works, and Celia is free at the start. |
| Starter Warriors | Arthur, Bella, Marlena, Claire, Celia | William steps out when Claire and Marlena arrive. |
| With a tank partner | Durant, William, Celia | The two SR Warriors cover tank and damage for the opening stages. |
All three squads stay in one faction, which is why William fits so easily. Compare the lineups that the rankings test on the best team page, and see where each partner stands in the tier list.
Frequently Asked Questions
Is William good in Last Asylum Plague?
He is a placeholder. William gets a C from 5 of 5 lists, and they treat him as a damage dealer for the first chapters only. He is fine while you have no SSR or UR Warrior damage dealer, and he is not worth the upgrade materials once you do.
Which William skill should I level first?
Start with Twin Wind, which recharges every 5 seconds, then Whirlwind Blade, then Sword Gale. Twin Wind is cast twice as often as Whirlwind Blade, so each badge returns damage sooner. Unyielding is a support skill and costs no badges.
How do I get William?
Ten William Shards unlock him, whatever the server age. His story text puts the clinic first. He is a starter hero, so he needs no pack. Billy is a different hero, a UR Warlock Tank who unlocks once the server is 83 days old.
Who should replace William?
Any SSR or UR Warrior damage dealer. Claire is available from the start and Marlena is the UR choice. The Warrior damage dealers above SR are Marlena, Zoya, Claire, Kesso, Sivir. All of them play the same faction, so the faction bonus stays when William leaves.
William or Durant, which Warrior SR is better?
They do different jobs. William is a damage dealer with 524,421 power, and Durant is a Tank with 596,226. Their auto attacks use the same numbers, 73.5% to 175% ATK. Pick the one your squad lacks: Durant for the front row, William for damage.
