Skeleton Tech (Advanced Guide)

This section will cover the basics of Skeleton's tech and then all of the intricate details for Update 100. It overlaps with the daily sheet page and builds off of mechanics explained there.

Note: Much of this information is pedantic and is only useful in the most niche or extreme circumstances.

Normal Leveling	Melting and Skeleton will both start from Set 1. Hitting Ultra, taking Detachment and Vault Skips as Melting will not affect what Skeleton sees at all. Vault Skipping works as normal on Skeleton, skipping over a set. If Melting takes Heavy Heart then it will not reappear for Skeleton. Example: As Skeleton sees the same sets he can route differently based on what mutations he's seen as Melting. In this case Strong Spirit and Trigger Fingers are both in set 1, but Strong Spirit reappears in Set 3, meaning that Skeleton's route takes Trigger Fingers knowing that Strong Spirit will reappear.
Last Wish	If Melting takes Last Wish and then transforms into Skeleton on 5-1 in any loop, the Jungle Flower can still be entered. This will grant Skeleton an extra set allowing him to have 9 mutations. Jungle set ordering will not be reset if Melting transforms. This means that if Melting saw Jungle 1, then Skeleton would start on Jungle 2. Example: On the Melting route he enters Jungle in preloop, seeing the Jungle 1 set. Last Wish is taken a second time later in the route and Jungle is entered again in L1 after transforming. Skeleton then sees the Jungle 2 set, and will receive 9 mutations.
Patience	If Melting transforms into Skeleton while having Patience active (not yet granting the reroll), this will not grant Skeleton an extra mutation, but rather change the order of the mutations he sees. The first level up will grant Skeleton the Patience set, and then Sets 1-7 normally. Skeleton can then take Patience which will grant him the same set a second time, allowing him to siphon off a second mutation from the same set. Example: Melting takes Patience in Set 3 while entering Labs, but does not see the Patience set. The first set Skeleton sees is the Patience set upon leveling up, and then sees Sets 1-7 normally. In Set 3 he takes Patience which gives him the same set a second time, allowing him to get a second choice from it.
Redemption	Skeleton transforms back into Melting and is given 9 mutations with a choice of ultra. If Skeleton takes Patience and then Redemption in the same level up screen this will grant an extra mutation for Melting. The sets that Melting sees continues two sets after the one Skeleton left off on. If Skeleton ends on Set 8, then Set 9 is skipped, and Melting sees Sets 10-17. Detachment on this version skips the next set after then gives the three following sets. This would be sets 19-21 normally without any Vault Skips on Skeleton. On the extreme end, the max set number reachable in this version is Set 24. If Skeleton sees up to Set 11 with vault skips, then Melting sees Sets 13-20, and then Detachment sees sets 22-24. Example: Skeleton's route stops at Set 8 which is typical, thus Set 9 is skipped. Melting starts to see mutations from Set 10, which would end on Set 18 in this case.
Destiny	Crown of Destiny works for Skeleton starting with update 100. Skeleton will not see the Destiny set ever, but rather start on Set 1 and end on Set 9. This can be combined with Last Wish tech above, allowing Skeleton to get 10 total mutations. The odds of Skeleton getting an optimal set out of this is extremely unlikely in a vanilla run, however. As the same above if Patience is active when transforming, then Skeleton will see the Patience set first, then Set 1-8. Example: There are three example routes of a Weekly using Crown of Destiny. Route 1: Melting sees his Destiny set, and then sets 1-8 normally. As he sees Heavy Heart this permanently removes it from the pool, thus neither Skeleton route sees it. Route 2: Skeleton's normal route that skips the Destiny set, instead seeing Sets 1-9. Route 3: Patience is taken while Melting enters labs, so Skeleton's first set he sees the first slot from Patience which is Trigger Fingers. Patience is then taken in this route which uncovers the second mutation slot, Open Mind in this instance.
