How this is calculated
Stats are taken at full investment (level and star template, personal growth ratio, awakening and exclusive gear). Over a 30-second fight every skill casts on its cooldown, the first cast at its initial delay. Survivability = (HP + shields + healing) / (1 − damage reduction, capped at 75%). Defense and troops are computed server-side and are outside the model. Index 100 = the best squad built from all heroes in the game.
How to use the builder
Mark the heroes you own: a tap on a portrait turns the hero on, the “Select all” button takes the whole list. The builder runs through every five-hero squad from the marked ones and shows the best line-ups with a breakdown: roles, faction bonus, damage reduction, shields and healing, each hero’s contribution. From ten heroes on it also builds pairs of squads for modes that need two marches. The roster is stored in your browser, and after signing in it also follows you between devices.
The tabs above the list switch the measure: efficiency, survivability, damage per second or might. Under each squad the builder explains who can be swapped for a bench hero without loss and who carries the result. The “Open in the arena” button passes the best five to the team picker against a specific opponent.
Frequently asked questions
What is the best squad in Last Asylum?
A run through all 169,911 five-hero squads shows one shape: three tanks, with the two remaining slots taken either by two damage dealers or by a damage dealer and a support. Five tanks score 77 out of 100 efficiency points, five damage dealers only 15. The builder runs the same maths for the heroes you mark and shows the best squads made of them.
Which hero should I raise first?
Arthur. Without him the best squad of the remaining heroes reaches 64 out of 100: he alone brings the largest shield in the game and two sources of damage reduction. Without Billy, Ulfrid or Annie the score stays at 98, without Joker at 99. Arthur is also the cheapest UR to buy. The swap breakdown under each squad names the hero your roster cannot replace.
What does the faction bonus give?
Three heroes of one faction give +5% health, attack and defence to the whole squad, three plus two of another faction +10%, four of one faction +15%, all five +20%. Among the multipliers that depend on the line-up alone this is the largest. Counters work separately: Warrior beats Sorcerer, Sorcerer beats Ranger, Ranger beats Warrior, with a 20% damage difference.
How do I unlock the third squad?
A five-hero line-up can be assembled at any time and needs no buildings. The third squad in this question is the “Squad 3” building, a march queue: it unlocks at Sanctuary level 20. The second queue opens at level 8, and the fourth is visible from level 5 but needs an active monthly pass.
Does the builder account for my hero levels?
No: stats are taken at full upgrade, so the builder answers “what to invest in”, not “who to play tonight”. Two well-raised SSR heroes will beat five bare UR heroes. Spare heroes still work from the bench: the support skill gives the whole team +20% attack, health and defence for UR, +10% for SSR and +5% for SR, unlocked at 40 stars and level 30.
