Walls
Bosses and raids
The two fights that stall most players, and the daily modes that feed your progress.
Frost King (end of Chapter 2)
Get to one kill short of your next level, or hold a completed level-up quest unclaimed. Start the fight. When you're one hit from death, level up: it fully heals you, and you finish him. One player beat him on day six at under 400M power this way.
- Reported kill levels range from 193 to 226. Around 200 with a decent build is typical; 240M power alone only got one player to 40% of his HP.
- Melee: avoid the large red circle, weave in and out, and stay inside the big ring. Ranged players describe standing at the edge and attacking after each swing.
- Before the fight, auto-hunt the mobs around his arena for XP, upgrade your skills, and make sure your traits form a set.
- He's known to spawn the frozen-hero bug; see Protect your save.
Void Lord (end of Chapter 3, level 400)
Hits for around 46B. One player cleared him at about 5T power with no healing; those with S-wand healing say it's doable lower. A player at 450B rating expects to need around 10T. The step from the abyss lord to the void lord is roughly tenfold. Each new chapter release has nerfed the previous chapter's final boss, so if Chapter 4 ships, he gets easier.
Regular mobs worth knowing
- Treasure goblins are on a timer and vanish. Kill them fast; a stunning weapon (mace) helps.
- Frosthold order: Wraiths, then Ice Bones, then Dark Knights. Fall back to Redrock Valley Wolf Riders if needed.
- Chapter 3 skeletons are easy and drop green orbs.
Boss raids and Invasion
- Boss raids: five tickets a day, extra tickets are the one thing worth buying with gems daily. Each boss drops its own element orb; those buy eternal stones and shards in the Exchange shop.
- Invasion: tickets are buyable with gems (top right of the Invasion screen), ten a day maximum. The timer cuts off ten minutes before reset to score. Leagues are "rooms" of the same tier, and lower leagues contain bots and cheaters; a promotion sometimes fails to pay out (known bug).
- Invasion points and raid points are your free path to exotic hero shards. Spend them there.
- Regular Season for Invasion arrives with v26.0.0. Expect the meta to shift.
