AoS/Baselard manip

2025-02-25T04:05:35Z

Halgorithm:

The Baselard manip is a [[AoS/RNG_manipulation | manip]] to obtain the Baselard weapon drop from a Zombie in the first corridor after starting the game. The Baselard is useful because of its high base damage compared to all other weapons available early on in the game.

= Cutscene skip version =
{{#ev:youtube|mKplgAWgrN4|550}}

This is the standard version of Baselard manip, performed at the beginning of every standard route for non-NG+ Soma categories. It requires having beaten the game once in order to be able to skip the intro cutscene, which would otherwise make RNG calls.

# Slash 3 times anywhere in the first room.
# After the door closes, short hop and throw a spear anywhere on the slope to kill the first Zombie. The timing of the first spear throw doesn't matter much as long as the first Zombie dies.
# At the middle of the pyramid-shaped pile of bricks in the background, roughly when the front of Soma's head touches the dark vertical line separating the top two bricks, short hop and immediately throw a second spear.
# As soon as you land from the hop, quickly hop again and throw a third spear at the edge of the brick pile.
# The farthest Zombie should die to the third spear just before the closer Zombie dies to the second spear, which should drop the Baselard.

For the [[AoS/Soma_Any%25 | Any%]] and [[AoS/Soma_All_Bosses | All Bosses]] categories where gaining XP early on is important, it can be useful to also throw a fourth spear when Soma's head touches the edge of the column in the background, potentially killing one or two Zombies which always spawn there. An earlier throw will kill one Zombie, whereas a later throw will kill both. Too late of a throw will miss both.

== Troubleshooting ==
You can hold up+right the entire time to make the inputs for walking and throwing the spears simpler.

If the closer Zombie doesn't die from your second spear because the spear vanished, that means you threw it too early from too far left of the bricks pile midway line.

Similarly, if the closer Zombie doesn't die from your second spear landed because it landed too far to the right of it and missed, that means you threw it too late from too far right of the bricks pile midway line.

If both Zombies die but no Baselard drops, it's because your third spear throw was too late and the farther Zombie didn't die on the first possible frame.

AoS/Creaking Skull manip

Halgorithm: mention Soma categories that use this manip

The Creaking Skull manip is a [[AoS/RNG_manipulation | manip]] performed in the [[AoS/Soma_Any%25_No_0HP | Any% No 0HP]], [[AoS/Soma_Glitchless | Glitchless]] and [[AoS/Soma_Debug | Debug]] categories to obtain the Creaking Skull soul early in the game. Creaking Skull is a versatile soul for combat, movement and manips throughout runs due to its long reach, high damage and low mp cost.

= 5-backdash version =
{{#ev:youtube|rKIvUEXK8wY|||||start=60}}
''Timestamped video with input display''

This version has fewer inputs, but can fail if the player takes too long to perform the first backdash, as looking at the Axe Armor for a while will cause its AI to call RNG more often.

= 4-backdash version =
{{#ev:youtube|Ouj6GGswDpY|||||start=231}}
''Timestamped tutorial video with input display by Chewy4u''

This version avoids the risk of failure from taking too long to do the first backdash, but requires an extra whiffed slash in each room.

= Soulverlap ending =
{{#ev:youtube|k4se8XCojW0|||||start=75}}
''Timestamped video of a soulverlap on the 5-backdash version''

Both versions of the manip can optionally finish with a [[AoS/Glitches#Soulverlap | soulverlap]] to save roughly 1 second, at the cost of 59 HP. Before the killing blow, walk to the right far enough to that when you are knocked to the right when you jump. The instant you land after the knockback, jump and slash to the left. The final slash must connect before Creaking Skull's bone slam attack hits the floor and creates stone particles, which advance RNG.

It is possible for Soma to level up and collect a new soul on the same frame, usually by standing inside of the enemy which drops the soul when killed. If this happens, the soul description text box will be visually distorted during the levelup pause, and once the game unpauses the soul description text box will be automatically dismissed, saving a small amount of time.

AoS/RNG manipulation

2025-02-25T01:26:45Z

Halgorithm:

Most Soma categories make heavy use of RNG manipulation sequences (commonly called "manips") to guarantee that specific items always drop from certain enemies. This allows runners to utilize routes which would otherwise require impossibly low drop odds to succeed.

= Overview =
Whenever a new game is started or a save file is loaded, the RNG seed will always be reset to the same value. From that point, a runner can perform movements and actions which deterministically advance the RNG value to one that produces the desired drop.

Julius mode is unable to perform manips, as it has no method to suspend and reload the game.

= List of manips by category =
[[AoS/Baselard_manip | Baselard manip]] is used in the standard route for every category except NG+. It is performed at the very start of the game, and is a fundamental manip Soma runners should know.
