Guildrun Modifier Pool

What Modifiers Are

In Guildrun, a modifier is a run-level rule applied when you start or advance a difficulty tier. Modifiers can increase enemy health, add elemental resistances, reduce healing effectiveness, limit shop rerolls, or inject special relic variants into your draft options. Multiple modifiers stack on higher tiers, which is why difficulty eight feels dramatically different from difficulty three even with the same hero roster.

Modifiers are distinct from relics and items. They are not choices you pick — they are constraints the game imposes. Your job is to read them before committing to a build direction. The difficulty guide explains unlock order; this page catalogs how modifiers interact with loot pools.

Difficulty Tier Progression

The demo ships eight standard difficulty tiers before endless mode unlocks. Early tiers introduce one modifier at a time so you learn mechanics: reduced gold, tougher elites, or limited healing. Mid tiers combine two or three modifiers simultaneously. Top tiers stack aggressive enemy scaling with player restrictions such as fewer shop slots or increased reroll costs.

Endless mode adds rotating modifiers each cycle, which refreshes relic and item relevance for leaderboard chasers. If you plan to push endless, favor flexible relic themes from the best relics page rather than brittle single-element plans.

• Tiers 1–2: tutorial modifiers, mostly enemy stat bumps.
• Tiers 3–4: economy and healing restrictions appear.
• Tiers 5–6: combined enemy buffs plus shop limitations.
• Tiers 7–8: maximum standard modifiers before endless unlock.
• Endless: rotating modifier sets per cycle with leaderboard tracking.

Modifier Effects on Relic and Item Pools

Some modifiers add rare or cursed relic variants to your draft pool. Cursed relics trade a penalty — reduced max health, slower shops — for a powerful bonus. These appear more frequently when the active modifier explicitly mentions relic chaos or greed mechanics. Other modifiers filter shops toward defensive items when enemy damage modifiers are active, subtly steering your purchases.

Understanding pool changes prevents misreads. If a modifier says elites drop bonus relics, route toward elite encounters even if they cost health. If a modifier reduces item rarity in shops, prioritize relic power instead. Cross-reference the relics guide and items guide when planning around pool shifts.

Building Against Specific Modifiers

Healing reduction modifiers demand sustain relics and shield items rather than raw healing. Armor bypass modifiers require health pools and damage mitigation relics instead of block-heavy setups. Elemental resistance modifiers on enemies push you toward physical damage or alternate elements — a reason hybrid pivot builds remain popular. Read the pivot mid-run guide before abandoning an element plan; sometimes one item swap suffices.

Economy modifiers that shrink gold income reward early gold relics and flawless victory bonuses. Combat modifiers that spawn extra enemies favor area damage and scaling relics over single-target burst. Defensive modifiers on your heroes — such as reduced starting health — mean you should draft sustain earlier than usual.

Tracking Modifiers Across Runs

The in-run modifier panel lists every active rule with tooltips. Before each relic draft or shop visit, scan for changes — endless mode rotates modifiers without restarting the client. Our difficulty tracker tool lets you log which tiers you cleared and which modifiers appeared, helping you prepare for repeat attempts.

Community notes on modifier interactions update frequently during the demo period. If a modifier description seems ambiguous, test in a save-scummed run using the save and resume feature before committing to a leaderboard attempt. Full release late 2026 may expand the modifier catalog beyond demo scope.
