Mad King Redemption Upgrades Guide: Brotherhood, Corruption, and Meta Progression

Why Mad King Redemption Upgrades Decide Every Run

Mad King Redemption upgrades are the quiet engine behind every good run in Aldermere. On the surface the game is a 2.5D brawler — you punch, dodge, throw, and clear a room the way you would at a coin-op cabinet. Underneath, it is a roguelite, and the power that carries you past Baron Morgrim and into the Shadowmere Desert is earned in the Brotherhood hall, not on the battlefield.

That is exactly why Mad King Redemption upgrades matter more than a lucky run. Death is not a reset. Every failed attempt feeds the Brotherhood, and the Brotherhood feeds you back. Understanding which upgrades persist, which ones expire when you die, and which ones actively hurt you is the single highest-value lesson a new player can learn during Early Access.

This guide breaks down the upgrade economy piece by piece: where upgrades come from, how hero progression differs from shared meta progression, and how the Corruption mechanic turns raw power into a gamble.

The Brotherhood Hub: Every Upgrade Source Explained

The Brotherhood is where every run begins — described by the developers as a last resort of sanity. It is a hub populated by NPCs who unlock through quests, and those NPCs are your upgrade vendors. Some sell gear, some expand the archive, some unlock mounts, and all of them contribute to upgrades that outlast a single run.

The pattern here is important: none of these vendors are simple vending machines. They unlock through quests, which means the upgrade tree is gated behind play, not just currency. If an NPC is standing silent in the hall, the answer is usually a quest you have not finished yet.

For the full roster and current state of the hub, the official Mad King Redemption website is the most reliable reference, since Early Access patches shift details month to month.

Hero Progression vs. Shared Meta Upgrades

One of the most common points of confusion for new players is the difference between leveling a hero and upgrading the Brotherhood. They are two separate systems, and they scale differently.

The practical consequence is that hero progression rewards specialization while Brotherhood upgrades reward breadth. If you main Valraven, the Swordmaster, you will feel his block timing and tempo improve as his arc unlocks biome by biome. But the Brotherhood upgrades you buy with Brogan or Kael will also benefit Branok, Darkblade, and Elowen the next time you swap.

Here is how each hero's kit suggests you direct those shared upgrades:

Elowen is the clearest example of why shared upgrades matter. He is weak in melee with only his staff, so any Brotherhood upgrade that boosts his summoned minions or his healing effectively patches his biggest weakness. A player who only ever bought upgrades for a brawler will find Elowen unplayable until they invest in the caster side of the tree.

Corruption and Forbidden Powers: Paying for Power

Not every upgrade in Mad King Redemption is a straight improvement. Forbidden Powers are the spells the Pact forbade, and you choose one for the run. Each cast fills a Corruption Bar. When that bar breaks, you enter a Corrupted Phase — and then you crash, standing exposed.

That risk-reward loop is the most distinctive mechanic in the game, and it changes how you value upgrades. A build that ignores Corruption entirely plays safe but caps its ceiling. A build that leans into it deletes rooms but hands the enemy a free punish window at the worst possible moment.

Because Corruption is run-scoped, the smartest approach is to treat it as a resource with a known cost, not a mystery. If you know a boss phase is coming and your Corruption Bar is nearly full, holding back a cast is often worth more than the damage you would gain.

Practical Upgrade Priorities by Run Stage

Knowing the systems is one thing; spending well is another. The table below is a general framework, not a rigid rule set — the developers actively invite balance feedback through the game's Discord, so priorities can shift between patches.

A few actionable habits that pay off quickly:

• Finish quests before farming. A locked NPC is a closed upgrade branch. Quest completion is the real bottleneck in the early game.
• Buy breadth before depth. Shared Brotherhood upgrades are the only purchases that help when you switch heroes.
• Test one Forbidden Power family per hero. Bones plays differently on Branok than Shadows does on Darkblade.
• Track your Corruption crashes. If you are crashing more than once per room, you are over-casting for your current build.
• Re-check the shop after every major patch. Early Access updates ship frequently, and the official roadmap notes a major patch cadence since launch.

What the 1.0 Roadmap Means for Your Upgrades

The key takeaway: four more heroes arrive with version 1.0. Every shared Brotherhood upgrade you buy now becomes more valuable later, because the same purchase will apply to eight characters instead of four.

Frequently Asked Questions

Do Mad King Redemption upgrades carry over between runs? Yes — the core meta layer does. Brotherhood upgrades and hero progression persist across deaths. Only in-run pickups and your Corruption state reset when a run ends. That split is what makes the roguelite loop work: you always walk back into Aldermere slightly stronger than last time.

Which NPC should I unlock first? Brogan the Blacksmith and Kael the Master Mage are the most direct upgrade vendors, so prioritize the quests that bring them online. After that, Seraphina and Garrett open risk-and-reward branches that suit players who already understand the Corruption system.

Is Corruption ever worth maxing out on purpose? Community discussion around the Corrupted Phase generally treats it as a burst tool rather than a permanent state. The crash leaves you exposed, so the safe pattern is to push the bar during a boss's vulnerable window and hold back when you are surrounded by elite enemies.

Are Mad King Redemption upgrades pay-to-win? No. The upgrade paths described here are earned through quests, currency from runs, and progression — not purchased with real money. The current Kickstarter funds a Founder's Edition with cosmetics, physical rewards, and a possible SEGA Mega Drive port, not gameplay advantages.

The Bottom Line

Mad King Redemption upgrades are not a side system bolted onto a brawler — they are the spine of the roguelite loop. The Brotherhood hall, its quest-gated vendors, the shared meta tree, and the Corruption gamble all feed the same idea: every run should leave you better prepared than the last. Learn where upgrades come from, spend wide before you spend deep, and treat Corruption as a tool with a price tag rather than a trap. Aldermere rewards the patient sinner.
