To unseal a kekkai, the player must place "runes" in a specific order and is given a number of attempts to try to unseal it. Just think of this as Mastermind.
Strategies on unsealing the kekkai
- Select only 1 type of rune and put two of the same runes in the kekkai.
- Repeat Step 1 for each type of rune until two known runes are found for the kekkai.
- Using the two known runes, make a random selection of those two runes.
- If a random selection has 2 misplaced runes, Reverse the implaced runes
- Select only 1 type of rune and put three of the same runes in the kekkai.
- Repeat Step 1 for each type of rune until three known runes are found for the kekkai.
- Using the three known runes, make a random selection of those three runes.
- If a random selection has 1 correct rune but 2 misplaced runes, keep one of the runes in the same slot but swap the other two runes. If this doesn't occur, skip to Step 5.
- If all of the known runes are misplaced, then move then all in different slots.
- Repeat Step 5. This counts only for every the 3 misplaced-rune attempts.
- try use rune
- To start off, do 2 Green Runes, then 3 Red Runes. If 2 runes are correctly placed, its fine and go to Step 3. If only 1 rune is known and is placed or misplaced, see Step 2. If 1 rune is correct but 1 rune is misplaced, see Step 4. If 2 runes are known but are both misplaced, then they would be on the opposite side.
- If only one rune is known (either correct or misplaced), put all Green/Blue Runes for the next attempt to see if the Green Rune or Red Rune / Blue or Black Rune is not a chosen rune. If not, then skip this part.
- Repeat Step 1 but with 2 Blue Runes and 3 Black Runes. If the attempt ends up similar to Step 2, go back to Step 2, then skip this part after completing Step 2 after going back.
- During Step 1 or Step 3, if there is two known runes for the attempt but one of them is misplaced while the other is correct, put one rune of the two runes in the first slots to figure out where they should be added.
- If Step 1 and Step 3 are correct the first time, place an Orange or White Rune in the end to figure out the fifth rune.
- Now that you have every known rune, figure out the first two slots by checking your attempts. The rune that isn't going to be used to unseal the 5-Rune Kekkai will be used to figure out the other runes slot without giving another slot. So figure out the first two slots, then place the non-known rune in the other three slots. If the first two runes are not in the correct slot, then you should know that you will swap around them later.
- Next, put the non-known rune in the first three slots, then place one rune in the last two slots that you know that are going to be on the right side. If the rune is misplaced, then that rune will appear in the middle slot. If not, repeat this step with the next rune. TIP: The non-known rune DOES take place in this method for finding out the positions of the known runes.
- Now you can complete this. With the known first three slots for the runes, place them there. Then, finish with the other two runes. If 3 runes are correct but if the last 2 runes are misplaced, flip the last two runes on your next attempt.
- First, the player placed two Green Runes in the first two slots, then the Red Runes in the other three slots. Since the runes are known and correct (or if they were both misplaced) the player skipped to Step 3 in the above strategy.
- For the second attempt, the player placed two Blue Runes in the first two slots and three Black runes in the other slots.
- Since there is only one rune known and it was correct (or if it was misplaced), the player then selected all Blue runes for the next rune to see which of the two runes doesn't belong in the Kekkai and that would be the Black Rune.
- Since there are two more runes that needs to be known, the player did the same method (See Step 1 or Step 2 in this example) using the Orange and White Runes. They were both misplaced which means that both the Orange Rune and the White Rune will have to go on the opposite side.
- The player knows that White Rune and the Red Rune will have to go on the left side but to figure out which slots on the left side they go, the player placed one of each of those two runes in the first two slots. Since the player only wants to know the first two slots, the player then takes the Black Rune, which isn't a known rune for the example to help the player find out which slots the known runes are suppose to be in. If they were both misplaced, the player would flip them later.
- Then, to figure out the middle rune, the player placed the Black Rune (that is the not-known rune) into the first three slots (even the middle slot) and the Green Rune in the last two slots, since the player knows that the Green Rune is going to be either on the right slots or in the middle slot. It was in the middle slot though, which makes it easier. If not, then the player would have tried another rune color, which would have been a Gold Rune or White Rune.
- Now that the player knows the first three correct slots, the player put the runes in their correct slots but then with the last two slots, the player makes a guess (50% chance to get it correct in one shot) and puts the Blue Rune first, then the Gold Rune last.
- But since the Kekkai wasn't sealed from it (3 correct runes and 2 misplaced runes), the player simply flipped the last two runes.
