View source for 13%

13% is the lowest amount of items needed to beat the game by defeating all major bosses while staying in-bounds, but possibly with use of [[L+R Walljumping]] or [[Yellow Suit Glitch#Draygon *CF|Draygon ammo underflow]].

== Completed Categories ==

There are currently four 13% categories that have been completed RTA, which are [[13% xCharge]], [[13% PbPb]], [[13% IcePb]], and [[13% xPb]]. See these pages for a discussion of these specific categories. Also see [https://docs.google.com/spreadsheets/d/1WViqg4XGGtGQo0uQ16SogENdTBAaqPqqZUYoZJbu7Pk/edit?gid=1386063460#gid=1386063460 this spreadsheet] for a current list of all 14% and 13% records. Completed categories use tech such as 10 missile zebs, underwater walljumping without L+R, everest slopespark, and 10pb underflow.

== Theoretical Other Categories ==

Here, some other theoretical options for itemsets in 13% are considered, though these are likely too difficult to ever be completed by a human.

=== 13% Speed (TAS) ===

This is the fastest TAS option. Sniq authored the [http://tasvideos.org/5291S.html currently published TAS] for the category, obsoleting the previous two Low% branches, which used the item sets from [[14% Ice]] and [[14% Speed]]. The following are the colledted items:

*[[Morphing Ball]]
*[[Bomb|Bombs]]
*[[Charge Beam]] (for bosses)
*[[Speed Booster]] (for Zebetite skip, and building Spike Suits for Mt Everest, pre-Botwoon Hallway, and for exiting Draygon's room)
*[[Varia Suit]] (to survive [[Mother_Brain#MB2|MB2's]] rainbow beam)
*2 [[Energy Tank|Energy Tanks]] (to survive MB2's rainbow beam)
*1 [[Reserve Tank]] (to survive MB2's rainbow beam, and to make the Everest Spark possible)
*2 [[Missile]] Packs ([[List of Missiles#Brinstar 1|Awakening]] and [[List of Missiles#Crateria 2|Moat]]) (to open red doors and defeat [[Mother_Brain#MB1|MB1]])
*2 [[Super Missile]] Packs ([[List of Super Missiles#Brinstar 2|Early]] and [[List of Super Missiles#Wrecked Ship 1|Wrecked Ship (Left)]]) (to open green doors and defeat MB1)
*1 [[Power Bomb]] Pack ([[List of Power Bombs#Brinstar 1|Red Brinstar Elevator (Lower)]]) (to open orange doors)

The biggest obstacle towards human completion of the TAS branch of 13% is the spikesuit generation in Colosseum, given that it involves multiple instances of speedkeep movement in order to maintain dash speed in building the short charge.

It should be noted that this is one of the most likely categories for an RTA completion without [[L+R Walljumping]] or underflow. There are five hangups:

# Getting to Fish Tank. This is solved by a gravity jump from the broken tube with a flash suit.
# Climbing Mt. Everest. This is solved by Everest Slopespark, which has a triple frame perfect RTA setup.
# Getting to Botwoon. There is a TAS method (used to make 13% Speed possible on PAL) done by clipping into the ground, and then using double knockback from a Puyo and a bomb to destroy the ground you are clipped into to "slopespark" in [[Botwoon Hallway]], destroying the speed blocks while maintaining a flash suit. This has not been looked at RTA, but would at best be as difficult as Everest Slopespark.
# Getting past Botwoon ETank. The current RTA setup for Everest Slopespark needs 1+2 Energy+Reserve Tanks. Thus, this either requires an RTA setup for Everest Slopespark with fewer tanks (by lining up health drops), or a suitless slopespark setup in [[Botwoon Energy Tank Room]] to clear the speed blocks.
# Climbing Halfie Climb Room and getting out of Draygon. With the above setups, you can either spark up [[Halfie Climb Room]] or use [[L+R Walljumping]] and then spark out of Draygon. So either a slopespark setup needs to be found to get to the top of Halfie Climb Room (potentially using Zoa and the closing door), or an RTA method for charging a spark in [[Colosseum]] needs to be found.

The combination of these things would make this category multiple times as hard as 13% PbPb, and by far the hardest category ever completed by a human.

=== 13% SpeedPb ===

This would be an amalgamation of the IcePb and the Speed options. The spikesuit in Colosseum would not be needed, since a flash suit is gotten from the crystal flash at Draygon. Thus this is technically more humanly viable, but is much harder than the Pb-Pb option. It requires everything that makes 13% speed difficult except for the colosseum shortcharge and the double puyo knockback thing.

== Hypothetical Categories without L+R or Underflow ==

There are no theoretical categories at this time that can avoid both L+R and underflow. There are three options for this that still have a road block preventing it from being possible. All of the following categories would utilize the 10 missile Zebetite kill.

* '''13% GravCharge:''' This would be similar to 14% Ice, except Ice Beam would be skipped. However, there isn't a known way to get through [[Botwoon Hallway]] without Ice, Speed, X-Ray, or a Power Bomb. Moondance in a 2-tile opening will eventually gain too much speed to fall back into the opening and continue moondance, but won't gain enough speed to clip through the pipes below. TAS dance is a subpixel away from clipping through, but again can't gain enough speed. This is the second least likely category to be solved without L+R.

* ''' 13% xCharge:''' If a way can be found to ascend [[Halfie Climb Room]] in Maridia with only X-Ray and Bombs, the current 13% xCharge could be done without L+R. However, there isn't a way to do this, since all means of traversing the room require either Gravity, Ice, Grapple, a spark, or L+R. The only way is if some odd form of R-mode, G-mode, or X-mode is found to get up. A solution has yet to be discovered and this is the least likely category to be solved without L+R

* ''' 13% Speed:''' A human version of the 13% Speed TAS is another option, but it still has barriers from even being theoretically possible. The biggest obstacle for is the colosseum shortcharge (on NTSC) or a weird double knockback thing with a bomb and a puyo (on PAL), which aren't humanly possible yet. A triple frame perfect slopespark in Mt. Everest is required and to avoid L+R, the resulting sparksuit would need to be converted into a bluesuit. That means that pre-maridia spikesuit, tube grav jump, fish tank underwater walljumps no L+R, slopespark → bluesuit conversion, and pitless Colosseum need to be done in one go without saving. This may be the most likely to become possible for humans, but would be the hardest category ever completed by a human.
