Party Progression: Early to Late Game

Recommended core

Crusader + Healer + Archer + Mage is the recommended balanced campaign core once all four are available: protection, recovery, ranged focus and elemental coverage. The same core remains useful late in progression; a new paid hero is not automatically an upgrade.

These are role-based recommendations for the installed build, not a measured live tier list or a guaranteed clear. Current skill coefficients, unlocks, enemy scaling and pet bonuses can change. Use only skills and slots you have unlocked; keep an available skill until its suggested replacement opens.

Early game — establish a stable four

Use Crusader + Healer + Archer + Berserker from the heroes you have unlocked. If Mage is available sooner or waves favor magic, use Mage in the Berserker slot. If you have fewer than four deployed slots, preserve protection and recovery while building toward the full party; do not spread resources over all eight heroes at once.

Put Crusader in front, with Berserker as the second melee when present. Keep Healer and Archer behind cover.
Spread enough to reduce area damage while keeping the party within group-heal range: the formation tutorial describes three hexes. Do not strand the Healer at the edge.
First fix deaths: tank durability and enough healing. Then invest in the damage source that improves clears. Avoid deep upgrades on short-lived equipment simply to chase rarity.
Bring an unlocked source of burning before Hydra. Fire Arrow, Fireball or Seismic Slam are candidates according to your roster.

Move to the next phase when the team survives ordinary waves reliably and encounter mechanics, rather than missing basic equipment, are your main obstacle.

Mid game — use the elemental core

Default to Crusader + Healer + Archer + Mage. Use fire and cold deliberately, rather than equipping every unlocked skill and hoping for a useful reaction. Keep Berserker available for fast wave clears or a second melee when it actually performs better.

Choose four usable skills per hero from Hero Loadouts; adapt them to each boss.
Improve the main damage dealer's weapon and relevant stats after the front line is stable. Healer benefits from Intelligence and Magic Power; tank durability still matters when damage dealers become stronger.
Use Commander Doctrine and hero talents for the role you need. Read the current node and its requirements; no fixed talent path or numerical breakpoint is implied here.
Socket Legendary and better gear when the bonus and cost justify it. The installed preview uses one socket on Legendary, two on Unique and three on Mythic; check the current piece because the server can override those counts. Select gems by the actual stat and compatible piece, not their color alone.

Late game — specialize by encounter

Keep the balanced core for unfamiliar campaign stages and higher difficulties. A successful Normal clear does not prove that the same offensive setup is safe on Madness.

Campaign progression: keep Crusader + Healer, then choose Archer + Mage for ranged and elemental coverage. Change defensive tools and resistances before replacing the support core.
Fast wave farming: try Crusader + Healer + Berserker + Mage. If this clears more slowly than Archer + Mage, use the latter. Once the stage is safe, a second offensive change is an experiment, not the progression default.
Single-target / World Boss: start Crusader + Healer + Archer + Mage. If owned and geared, compare Assassin in the Mage slot when the encounter does not need Mage's element or area coverage. Judge total damage over the full attempt, including deaths.
Abyss: start with the durable core and recovery tools. Medic in a damage slot is an optional poison-and-recovery variant after Transfusion unlocks; keep the Healer until the run demonstrates that less recovery is safe.
PvP: start from the core, then counter the opponent. Assassin may add back-line pressure, Paladin melee utility, and Medic poison pressure. They are matchup options, not a proven global ranking or a reason to buy a hero.

Change one thing at a time

When the team fails, identify the cause before spending resources: front-line death means protection, back-line death means positioning or target control, Hydra healing means burn uptime, a protected boss means timing or element, and a safe but slow fight means damage. Repeat a comparable encounter after one adjustment. Replays and current result screens are more informative than the largest displayed power number.
