- Out Of Date
Introduction
Due to the latest balancing changes, we do not recommend playing this build anymore, as it does not meet the high standards we apply to our guides in terms of fun and performance. We are leaving it up as a reference and it might be revived in a later patch.
The build will still function, but as it’s claim to fame was its ability to very quickly, effectively and most importantly cheaply farm Legion we have deemed it too expensive for its purpose and sadly had to legacy it. If you are willing to spend the currency to play the build, it is still fully functional.
Be advised though, it will be far more expensive and other similar builds that outscale it.
In recent years Corrupting Fever has been a steady choice among mapping focused players for Leaguestart. It’s fast, relatively sturdy and not too difficult to get going. As a bonus, it can be scaled into a true late-game monster if you are willing to invest, through a transition over to Gladiator.
In many ways, it has a play style similar to that of bleedbow, where you rapidly spread a high damage DoT onto every enemy you meet and watch them explode.
We’re not a Gladiator I hear you say, how do we achieve explosions without explode chest, forbidden Flame and Flesh jewels or a specific cluster notable? 
Haemophilia gloves is your answer. These babies will functionally do the same for us.
As Spellslinger has been horribly nerfed over the years, we rely on The Poet's Pen to alleviate that issue for us. This can be a bit expensive on Leaguestart, but the build does not need the wand until it is ready to move into red maps. That said we want to get this as early as possible.
Build Assesment
Pros
- Excellent clear speed and movement speed
- Very good League starter
- Fairly straightforward gear progression
- Long-range playstyle provides innate safety
Cons
- Relies heavily on a few select Uniques. Some of these can be expensive early on.
- Namesake skill can not be played from the start and needs to be transitioned into
- Can feel a little clunky to level until midway through the campaign
Playstyle and Build mechanics
Corrupting Fever itself is just a Damage Over Time effect that is applied by other things. This means we need a delivery system, in order to get our DoT going on targets. This is where Kinetic Blast comes in. It fires projectiles that explode on impact. Once we combine this with 
Greater Multiple Projectiles Support, we have multiple projectiles fired in rapid succession that all explode on impact. Thus we very rapidly stack our DoT on targets and watch them explode through the use of Haemophilia.
This takes care of our clear needs, and it does decent damage to single targets. But our single target damage would still be lacking if this was all we had going for us.
Through Spellslinger early on, and later on through The Poet's Pen, we have Exsanguinate and 
Reap going off automatically when we attack with Kinetic Blast.
Some of you may have noticed that Corrupting Fever only has a duration of 7 seconds. Pressing this every 7 seconds to refresh the buff would be incredibly annoying. Thankfully, Corrupting Fever is refreshed when we pay a certain ammount of life. Thus we can keep it active by simply attacking targets with Kinetic Blast linked to 
Lifetap Support.
This means at the end of the day, that we are a one-button build while mapping. Exluding movementskill, ofc. Many people, myself included, value this highly.
Defensive Layers and Damage Scaling
This build utilises a combination of the core defenses in the form of Armour, Evasion and Spellblock. We combine this with high chaos resistance, a Glorious Vanity in the name of Xibaqua and decently high regeneration. Overall this package keeps us quite safe.
The damage is scaled entirely through Damage Over Time Multipliers, Damage Over Time and Physical Damage modifiers. We spread DoTs around, and things die. Very straight forward.

Leveling
Unfortunately we cannot directly level our Champion with the skills the build is intended to play with. Most of them become available fairly early, but we sadly cannot access them until we are past Library as Gladiator does not get to have acces to all of these spesific toys. As a result, we level with physical damage skills until we can make the swap. Our choice here is, as will surprise nobody, Spectral Helix.
Spectral Helix
- Spectral Helix
- Lifetap Support
- Vicious Projectiles Support
- Brutality Support
Spectral HelixTotem Support
- Ancestral Protector
- Maim Support
- Culling Strike Support
Auras
- Determination
- Pride
- Vitality
