KR Battles Vault

Any-arena deck

One deck that holds up in all 5 arenas, for when you don't know where you'll play. You pick the cards before the match. Once the map loads, you decide how many of each tower to build.

The deck

TowerCodeRoleWhy it's in
Fuerte de BallesterosFBBoss killer (physical)Kills the bosses with magic armor or flying: Krum'Thak, Einar, Lord Malagar. Fast shots, hits fliers, and Aluvión fires 20 hits of 471–538 every 15 s.
Gema LlameanteGLMain damage + magic boss killerYour best tower. Melts high-health units with physical armor or none, and handles Ulguk-Hai, Gigante and Fortaleza Voladora.
Tesla x104TSArea damage (physical)Cheap opener near the gates. Its chain hits ground and flying packs: wasps, helicopters, crows, bats and the rival's flying boosters.
Mecha de BatallaMESupport (anti-stun)Its aura stops nearby towers from being stunned or disabled: boss tar, Triturador's rocks, and probably the rival's freeze boosters (Ventisca, Torre de Granja, Piedra Fundida). Misil Avispa does true damage.

The key idea: every boss has either magic armor, physical armor or none. With Fuerte de Ballesteros (physical) and Gema Llameante (magic) in the deck, you always have the right boss killer, even though you don't know which boss will come. Tesla covers flying packs, and Mecha protects your towers from the freezes and stuns that bosses and your rival's boosters throw at you.

Once the map loads: split by arena

Each map has 8 spots. Recognize the arena by how the map looks, then build this many of each tower.

ArenaThe map looks likeWhy
Arena 3
Bosque de Silveroak
green fields and farms×3×2×2×1Both bosses need physical (Krum'Thak has magic armor, Gul'Thak none) and Helicóptero, Gárgola and the rival's Globos Goblin fly. Lean on Fuerte; Gema handles Ogro and Campeón Orco.
Arena 6
Montañas Tormentosas
snow and ice×1×4×2×1Both bosses fall to magic (Ulguk-Hai blocks physical), so go Gema heavy. Tesla handles troll packs and the rival's flying golems; Mecha stops J.T.'s freeze and the rival's Ventisca.
Arena 9
Guarida de Bandidos
brown dirt with red tents×3×2×2×1Einar has magic armor and Capo none, so Fuerte is the boss killer; Gema melts the physical-armor brutes. Mecha answers Torre de Granja and Triturador.
Arena 12
Valle Desolado
dark rock and lava×1×4×2×18 of 11 enemies and both bosses have physical armor, so go Gema heavy. Tesla hits the dragon, bats and crows; Mecha stops Fortaleza's tar and Piedra Fundida.
Arena 15
Fronteras de Hammerhold
yellow desert sand×3×2×2×1Lord Malagar has magic armor and flies, so Fuerte is the boss killer. Tesla clears the wasp swarms in the air, and Gema covers Inmortal and Escorpión.

Build & upgrade order

  1. Stages 1–2: build Tesla x104 at NIV1 on a spot near the gates. It's cheap (90), hits groups and fliers. Then put one Gema Llameante on the best middle spot.
  2. Stage 2–3: look at the map to see which arena you're in (snow, lava, desert…) and follow that arena's split in the table above. Build Mecha de Batalla on the most central spot before the rival's freeze boosters show up. Take Gema #1 to NIV3 and buy Llamado Eldritch.
  3. Stage 3–4: fill the middle spots and take Tesla to NIV3. Buy Rayo first, or Sobrecarga first in the desert. Mecha to NIV3 with Misil Avispa.
  4. Stage 4–5: you don't know which boss is coming, so have Fuerte de Ballesteros (with Aluvión) next to the exit and your Gemas at NIV3 before stage 6. That's a physical and a magic boss killer.
  5. Stage 6: cast Sabotaje on the boss first. It lowers armor or magic resistance, so it works on every boss. Then use Golpe Definitivo while your boss killers fire.

Level-3 upgrades to buy

TowerBuy firstThenWhy
Fuerte de BallesterosAluvión (220)Vista Corta (180)Aluvión fires 20 hits of 471–538 physical damage every 15 s, about 10,000 damage in one burst. That's your best boss killer for magic-armored bosses. Vista Corta sends hawks to the same spot on your opponent's side and cuts the range of the tower built there by 17% and its damage by 20%. Buy it second, or first if your opponent has a dangerous tower on that spot.
Gema LlameanteLlamado Eldritch (180)Gema de Multiplicación (210)Eldritch blocks the path and does true damage. Multiplicación splits the beam across 2 targets, which is worse against a lone boss and better against swarms. In Arena 15, buy Multiplicación first.
Tesla x104Rayo (130)Sobrecarga (160)Rayo stuns 1 target for 4.5 s and is the cheapest. Sobrecarga has a 50% chance to hit everything around the tower. In Arena 15, buy Sobrecarga first for the wasps.
Mecha de BatallaMisil Avispa (205)Descarte de Residuos (160)Misil Avispa does 1,649–1,915 true area damage. Descarte slows by 40%. The anti-stun aura is automatic.

Spells

Golpe Definitivo

Save it for stage 6. It hits the strongest enemy in the area for 6,484–9,078, so it works on every boss.

Sabotaje

The flexible spell. It lowers armor or magic resistance by 76% for 14 s, so it helps against both kinds of boss. Use it on tough packs during the waves (18 s cooldown), and always on the boss right before Golpe Definitivo.

Ráfaga Solar

Your area damage for swarms (wasps, goblins, trolls, knights). Aim it down the longest straight road. Kills also send fire elementals to your opponent.

Hero

Bonehart

The best all-round hero. Fuerza de Aguja gives all 8 towers +3% damage in every arena, and Depleción de invasores cuts enemy magic armor by 5%, which helps your Gema towers. He flies, so blocking doesn't stop him.

Where to keep him: Early on, put him where the entry routes meet and use Nova de Enfermedad on the biggest pack. From stage 5, move him toward the exit to help your boss killers. In the desert, keep him away from Lord Malagar, who traps heroes.

Placements on every map

Open an arena to see where each tower goes on each of its maps. G is a gate, X is the exit, C is a rock mound.

How I picked it

I scored every possible 4-tower combination from your 18 towers against the enemies of every arena. Each arena score adds up:

Armor (28%)
How many of the arena's enemies a tower in the deck hits with the right damage type. The units your rival can send with boosters count at half weight.
Bosses (28%)
Whether each possible boss has a strong single-target tower of the right type that can reach it.
Fliers (15%)
Whether at least 2 towers can shoot flying enemies.
Area damage (14%)
Area damage for packs, and in arenas with 3 or more fliers it must hit the air too.
Card power (9%)
How strong the towers are on the tier list.
Anti-stun (6%)
In arenas where bosses or your rival's boosters can freeze or disable your towers, a deck with Mecha de Batalla scores higher.

6 Mago Arcano, Dominios del Genio, Mecha de Batalla, Cuartel de Mosqueteros0.9200.858

I picked the deck with the best worst-arena score (it is never weak, whichever arena you get), even though one deck has a slightly higher average: Fuerte + Gema + Mago Arcano + Mecha, which is weaker in the desert because it has no area damage that hits the air. These weights are my own, not tested in matches, and the anti-stun bonus assumes Mecha's aura also blocks booster freezes, which still needs a test. The arena-specific decks can be a little better when you know the arena.
