Itemization in Risk of Rain speedruns can be divided into three subcategories: the absolutely necessary items for fast movement (named here as Core Items), the bundle of common, uncommon and rare items you pick up besides those (named here as General Items), and the use item you pick up in the later stages, before fighting Providence (named here as Use Items).

#Core Items ##Gigantic Amethyst Use item (orange). Necessary to execute the Bandit Smokebomb glitch, to build up speed. This item should be kept until the later stages, or until your character is at a considerably fast speed (this is not a well defined threshold and it varies from runner to runner; once you start having trouble opening small containers and chests, it's a good time to stop stacking speed). ##Hopoo Feathers and Rusty Jetpacks Uncommon items (green). A bunch of these are necessary to execute the Out-Of-Bounds skip to Providence's room in the final stage. Also very helpful to move around stages and skipping over large gaps. The recommended amount of items is 3 Feathers and 2 Jetpacks, or 4 Feathers and 1 Jetpack; these will consistently allow you to jump to the top of the final stage and be able to perform OOB (Having extra Feathers/Jetpacks can make it easier, but you should be saving those for the item builds; likewise, cutting down on these to setup the item builds may leave you stuck trying to climb the ship or unable to OOB).

#General Items ##Attack Speed Requirements: (up to) 13 Soldier's Syringes, 1+ Laser Turbine Execution: Just keep shooting. (With high attack speed, mashing the button is better than holding it down) Pros:

• Consistency (not reaching 13 Syringes doesn't automatically mean you fail to execute the Prov kill)
• Doable with fewer syringes (only a tad bit slower)
• High attack speed charges Turbine faster, letting you time the kill on Wurms Cons:
• Overall slower than other strats

##One-Shot Requirements: 9 Crowbars, (up to) 10 Atg Missile Mk.1, 1 Ancient Scepter, 1 Brilliant Behemoth, 1+ Laser Turbine Execution: Position yourself on the spot where Providence spawns (inside his hitbox), then use Lights Out Pros:

• Fastest strat (with proper timing, you can kill Prov 1 and 3 on the first vulnerable frame)
• Even without Turbine, Wurms can be dealt with fast
• Doable with fewer Missiles (but riskier) Cons:
• Reasonable amount of items required (easier in Monsoon)
• Requires accurate positioning inside the hitbox where Prov spawns
• Requires missiles to proc (each missile stack grants you a 10% chance of spawning them)
• Not having enough crowbars means the damage dealt won't be enough to kill Prov in one shot

##Fire Shield Requirements: 10 Fire Shields, 9 Crowbars, 1 Infusion/Guardian's Heart, 1+ Laser Turbine Execution: Get hit by Providence to trigger Fire Shield damage, instantly killing him Pros:

• High amount of damage dealt
• Can be useful during the run to clear large groups of enemies
• Dealing on-contact damage and having a safety item can help in tight situations Cons:
• Large amount of common items required (easier in Monsoon)
• Have to wait until Prov attacks to deal damage (stick close to it to avoid losing extra time)
• Not picking up a safety item (Infusion, Heart, etc) means certain death to Prov

#Use Items ##Explorer's Key Execution: Around 1 second after Providence's Phase 3 starts spawning, trigger Key on the left side of the boss room to open the chests on the upper-left part of the screen; let Providence teleport to the left side to tank the missiles Pros:

• Consistency (missiles usually kill Prov, even if he's still alive it only takes a few hits to get him down)
• After Prov teleports to tank the missiles you can go straight to the panel to finish the game, hitting it as soon as you can Cons:
• Requires at least 2 Bundles of Fireworks to fully kill Prov
• Mistiming the Key or having Prov teleport a bit further away easily leaves him alive, which loses time and can get you killed

##Glowing Meteorite Execution: Trigger as soon as Providence's Phase 1 dies Pros:

• Turbine is no longer required
• Damages Wurms even before they appear (by hitting them on a lower platform, below the boss room)
• Often kills one of the Wurms, sometimes even kills both Cons:
• Meteors can kill you as well (painful way to end a run)
• No fast kill on Prov 3 if you're using attack speed build

##Marble Gate Execution: Set gate outside the boss's room, trigger when Providence's Phase 1 ends Pros:

• Fast kill on Wurms (by dropping down to the lower platform below the boss room, where they spawn)
• Fast kill on Prov 3 by baiting him to teleport to you while you're outside of the room, killing him instantly Cons:
• Requires better movement outside and around the boss room (prone to errors)
• Have to perform OOB again to get back in the boss room, losing some time
