4-Cost Carry Guide: From Win Streak to Secured Victory

1. Stage 2 Opening: Best early traits, key low-cost carries, and item crafting logic for the first 3 PvE rounds (win-streak vs loss-streak items)

The 4-cost carry compositions in this set (e.g., Mage, Gunner, or Oracle) generally need high HP when entering Stage 4, so the quality of the Stage 2 transition is crucial.

Best early traits: Prioritize traits that transition smoothly into your mid-game core. For example, if your final goal is Mage, keep cheap Mage units (e.g., Taliyah or Swain). If Gunner, keep Gunner units (such as Lucian or Jinx). Combine them with frontline traits like Sentinel, Bruiser, or Bastion to strengthen tanking. Common versatile early traits are 3 Noxus or 2 Juggernaut.naut + 2 Challenger provides AD and HP bonuses for early pressure.

Key low-cost carries:

• 1-cost: Cassiopeia – deals consistent damage over time, good for AP transitions. Poppy – an excellent frontline tank. Vi – Bruiser + Enforcer, can build tanky and deal damage.
• 2-cost: Swain – strong healing on the AP frontline. Jinx – Gunner trait, fast attack speed; Sett – Bruiser + Juggernaut, sturdy damage.
• 3-cost: Lux – Mage + Scholar, large AoE skill, mid-game core; Darius – Noxus + Juggernaut, high single-unit power.

Item crafting logic for the first three PvE rounds:

• Win-streak items: If your early drops let you craft a strong early item (e.g., Infinity Edge, Rabadon's, or Warmog's), craft it immediately to secure a win streak. For example, with BF Sword + Sparring Gloves, prioritize IE on Jinx or Darius. With Recurve Bow + Chain Vest, craft Titan's Resolve for the frontline. The goal is to strengthen immediate power to avoid losing Sta.2.
• Loss-streak items: If your early items are bad (e.g., all MR or Belts) and your composition needs specific items (e.g., Blue Buff or Guinsoo's), consider open fort or intentional loss streak, keeping only components instead of crafting items and saving gold for interest. However, loss streaking is riskier in this set. Only do it if your HP is healthy (e.g., 90+) and you're sure it will be perfect.CT items.
• General logic: For items in the first 3 PvE rounds (1-1 to 1-3), crafting priority is damage items (Rabadon's, IE, etc.) > frontline items (Warmog's, Thornmail, etc.) > utility items (Zeke's, Chalice, etc.). If your final carry isn't certain, hold components, but failing to craft a strong item by 2-1 can cost you HP.

2. Stage 3 HP leveling and stabilization: Should you level to 6 at 3-2? When should you roll down to lock HP? How do you transition smoothly from early to mid-game?

Level to 6 at 3-2?: In this set, leveling to 6 at 3-2 is standard, except when your economy is poor (e.g., loss streaking at low HP). Leveling gives an extra unit slot, increases power, and raises your 4-cost hit chance (5% at level 6). If your economy is strong and you're win streaking, consider leveling at 3-1. However, 3-2 is safer.

When to roll down to lock HP:

• 4-cost carry componentsSince it relies on 4-cost carries, avoid heavy rolling in Stage 3 unless your HP is very low (below 50) or your composition is collapsing. General strategy: after leveling to 6 at 3-2, roll a small amount (20-30 gold) to hit key 2-stars (e.g., 2-star Swain or Lux) or complete your mid-game traits (e.g., 4 Mage) to stabilize.
• Lock points: If you're losing too many fights or can't win PvE by mid Stage 3 (3-3/3-4), roll down to level 3-5 (down to 30 gold) to find a key 3-cost 2-star or 4-cost 1-star that can secure HP before Stage 4. But don't roll to 0. Keep at least 20 gold for interest.

Smooth transition to mid-game:

• AP transition: Early on, use "3 Mages + 2 Sentinels" or "3 Noxus + 2 Mages" as a bridge. In mid Stage 3, add Lux and Swain to get 4 Mages or 3 Noxus + 3 Mages, with Poppy or Sett on the frontline.
• AD transition: Early on, use "3 Noxus + 2 Challenger" or "2 Gunner + 2 Bruiser." At stage 3 mid, add Darius and Jinx, place Vi or Sett in the frontline, and get 4 Challengers or 4 Gunners.
• General tips: The key to transition comps is 'frontline + backline damage.' Prioritize frontline tanking such as Warmog's or Thornmail and backline damage (Jinx or Lux with damage items, etc.). At stage 3, if you reach a 4-cost with appropriate items (e.g., Azir or Aphelios), you can swap directly without rolling.

3. Pivot rhythm at 4-1/4-2: When to level to 7/8 and sell your carry for a full swap? Alternatives when you can't find core 4/5-costs

When to level to 7/8:

• To level 7 at 4-1: If your economy is healthy (50+ gold), level to 7 at 4-1 and look for key 4-costs (e.g., Azir, Aphelios, Lux). If your economy is poor (under 30), level at 4-2, but you must roll.
• To level 8 at 5-1: If you've hit your key 4-costs and they're 2-star at stage 4, level to 8 at 5-1 and add a trait (e.g., 4 Mages or 4 Gunners). If they're not 2-star, keep rolling at 7 but assess your HP.

Selling your carry for a full swap:

• At 4-1/4-2: Once you hit your key 4-cost (e.g., Azir or Aphelios), immediately sell your temporary carry (e.g., Swain or Jinx) and swap in the key unit to adjust traits. For example, AP comp: sell Swain and add Azir and Ahri for 4 Mages. AD comp: sell Jinx and add Aphelios and Zeri for 4 Gunners.
• Timing: If your temporary carry is 2-star and has matching items, you can keep it a bit longer, but if you don't swap by 4-2 at the latest, your power will fall off.

Alternatives when you can't find core 4/5-costs:

• AP carry fallback: If Azir doesn't come, use Lux or Veigar (if you have Rabadon's) as a temporary carry. Damage will be lower, though. If Ahri doesn't come, use Twisted Fate or Sylas.
• AD carry fallback: If Aphelios doesn't come, use Zeri or Xayah (if you have IE). If Jinx doesn't come, use Lucian or Caitlyn.
• 5-cost substitutes: If your key 5-cost (e.g., Senna or KSante) doesn't appear, use a 4-cost instead (e.g., Aphelios for Senna, Tahm Kench for KSante).
• Frontline substitutes: If your key frontline (Tahm Kench or KSante, etc.) doesn't appear, use Poppy, Sett, or Vi to maintain tanking.

4. Economy management: Win-streaking to level 9 and chasing 3-star 4-cost vs. lose-streaking for top 4 - economic thresholds

Win-streaking (high HP, high economy):

• Economic threshold: If your HP is 70+, gold is 50+, and your core 4-cost is 2-star, consider leveling to 9 (usually 5-5 or 6-1) to chase a 3-star 4-cost. At level 9, you can add a 5-cost (such as Senna or KSante) to raise your ceiling.
• Chasing 3-star strategy: After leveling to 9, if your economy is strong (50+ gold) and you have many copies of your key 4-cost (8+), roll while maintaining 50 gold interest to chase the 3-star. If you have few copies (5 or fewer), don't force it. Preserve your economy to avoid a power drop.
• Note: In this set, chasing a 3-star 4-cost is risky. If other players hold many copies, consider giving up and going for 5-costs or just preserving HP.

Lose-streaking (low HP, low economy):

• Economic threshold: If your HP is 40 or below or your gold is 30 or below, stop leveling and roll at 7-8 to secure a top 4 finish.
• Top 4 strategiesPrioritize 4-cost 2-star units and complete key traits such as 4 Mages + 4 Oracles or 4 Gunners + 4 Bruisers. If HP is very low (below 20), go all-in to improve quality and compete for better positioning.
• Whether to level to 9: In a losing position, unless your economy suddenly improves (e.g., consecutive loss interest and gold) and your HP is still at a decent level (40+), generally do not level to 9 and instead consider adding 5-cost units at your current level.

General Economy Principles:

• Interest: Keep at least 10 gold each round to earn interest, ideally 30-50 gold.
• Rolling Rhythm: When ahead, roll while maintaining 50 gold interest. When behind, you can roll down to 30 or 20.
• HP vs Economy Tradeoff: If HP is high but economy is poor, you can trade HP to build economy. If HP is low but economy is good, spend to preserve HP. The pace of this set is fast and HP matters, so don't be greedy with economy and don't lose too much HP.

This is the complete guide to this set's 4-cost carry strategy. Flexibly use early traits, item crafting, rolling timing, and economy management to steadily climb the ladder.
