WoW Forever Horizontal Progression: Biome Buffs, Situational Gear, and How It Works

Updated September 17, 2026: WoW Forever is built around horizontal progression: items with biome and creature-specific effects, gear you swap based on the situation, and power increases meant to be "responsible" instead of replacing everything you earned. Details come from two BlizzCon interviews: IGN Nordic sat down with Senior Game Designer Michael Nuthals and Lead Game Designer Tim Jones, and MMORPG.com talked with Senior Game Designer Josh Greenfield and Senior Art Director Jeff Parrott.

1. What Horizontal Progression Means in Forever

Forever keeps the level 60 cap and Classic-era structure, so the team needs a different reason for players to chase new gear. In the IGN Nordic interview, Nuthals described the goal directly: "Forever really is a promise to create a forever home for our Classic players." The answer is horizontal progression, where new items make you stronger in specific situations instead of a straight item level climb.

The system has three parts per the two interviews:

Items with biome effects, such as a speed buff while in desert areas.
Items with creature effects, such as extra damage against dragons or dwarves.
Gear you collect and switch between depending on what you are fighting.

That gives players a reason to run new content and to go back to older raids for pieces that fit a specific zone or enemy type.

2. Biome and Creature-Specific Item Effects

Nuthals described the itemization system in the IGN Nordic interview. Some items carry biome buffs, and the map is divided into different biomes such as desert zones. A raid item might grant a speed buff while you are in a desert. A trinket might grant extra damage against dragons or dwarves, and you could collect it first and use it later in a dungeon or raid.

Greenfield gave MMORPG.com a concrete example: Whitemane's Chapeau, which decreases the time it takes to use rez spells. He said the team has hundreds of these effects, so an item like a dragon-slaying set can stay desirable years after its own raid tier:

Effect type	Example from the interviews	Why it matters
Biome buff	Speed buff while in desert zones	Makes you faster in specific regions
Creature trinket	Extra damage against dragons or dwarves	Stronger against chosen enemy types
Class utility item	Whitemane's Chapeau lowers rez spell cast time	Useful in specific group scenarios

Greenfield added that a blue item can beat an epic for a specific purpose: "I don't think that there's anything saying we will never have a blue item that's better than an epic. And you might have a blue item that is better for a specific purpose than an epic, and I think that's great."

3. Gear Swapping and Old Raid Tiers

Collecting situational gear means players keep older pieces around. Nuthals said this encourages players to return to older content and switch between different pieces of gear depending on the situation. Instead of vendoring last tier's drops, you hold onto the set with the dragon bonus for the next dragon fight.

Greenfield framed this as taking cues from original WoW, where even in the move from raid tier to raid tier there were always things in the previous tiers you wanted. The original game had a failure mode too: by the time players reached Naxxramas, everything was already well optimized, so the new design aims for more incremental power steps.

4. How Much Vertical Power Remains

Forever is not removing vertical progression. Tim Jones told IGN Nordic that a Tier 2 raid will not arrive without better loot, and the team is focused on increasing player power in a responsible way. The reference point is Season of Discovery, which Jones said went too far: in Naxxramas, players were doing Wrath of the Lich King levels of damage at certain points, and that is not happening again.

The plan, per both interviews:

Design goal	What the devs said
Modest power gains per tier	More nominal power per step-up instead of big jumps
Old gear stays useful	Previous raid gear should remain relevant, like the Onslaught Girdle
No repeat of SoD scaling	Naxxramas-era Wrath-level damage is called out as the mistake
Horizontal items keep value	Hundreds of biome and creature effects planned

Jones noted that gear from previous raids should still be useful, naming the Onslaught Girdle as an example of an item worth keeping. The framing is that Forever stays a vertical progression game at its core, per Greenfield: "World of Warcraft is a vertical progression game, and that's part of the power fantasy, and we're never really going to take that away."

5. Storage: The 96 Slot Bank

Situational gear needs space, and Greenfield confirmed in the MMORPG.com interview that storage is being addressed. The default bank is much larger than Classic, roughly 96 slots, either twice or four times the original size depending on the comparison. Bags themselves start at the same size as the original game.

Greenfield explained the reasoning: players fill whatever space they are given, so the team does not want to expand bags too aggressively. Additional storage options are planned down the road, with nothing announced for launch.

6. Legacy as the Horizontal Layer

Greenfield also tied the Legacy system into horizontal progression in the MMORPG.com interview. Legacy gives bonuses and incentives for going down a certain path in its perk trees and for leveling multiple characters, much of which is not raw power gain and instead speeds up the leveling process for alts.

The caution is about grind. Greenfield said the team wants to avoid a situation where players feel forced to grind an alternate advancement system just to be effective, because that becomes a barrier for players coming in later or for alts. For now the plan is to steer clear of endgame power in the Legacy system, while leaving room to lean into it later.

7. Frequently Asked Questions

What is horizontal progression in WoW Forever?

Items give situational bonuses tied to biomes or creature types, so new gear makes you stronger in specific contexts instead of replacing everything you already own.

Is there still vertical progression in Forever?

Yes. New raid tiers will have better gear, but the power gains are meant to be modest and old gear like the Onslaught Girdle stays useful, per the BlizzCon interviews.

What are biome-specific item effects?

Buffs that only apply in certain regions, like a speed buff while in desert zones, described by Senior Game Designer Michael Nuthals to IGN Nordic.

Can a blue item beat an epic in Forever?

Yes for specific purposes. Josh Greenfield told MMORPG.com a blue item can be better than an epic for one specific situation, and that is intentional.

How big is the bank in Forever?

Roughly 96 slots for the default bank, much larger than Classic, with bags starting at the original size.

When does WoW Forever launch?

November 4, 2026, with the beta already running from September 17 and a subscription or Game Time required at launch.

Bottom Line

Horizontal progression gives Forever its identity: hundreds of biome and creature-specific effects, gear you stockpile and swap by matchup, and a 96 slot bank to hold it all. Vertical power is not gone, but the devs promise gentler steps and no repeat of Season of Discovery's runaway scaling. Plan to hoard situational sets, keep your Onslaught-style pieces, and treat mid-tier blues as real competitors for niche fights.
